Description: This invention relates to compositions comprising (A) at least one neutral or basic metal salt or boron-containing neutral or basic metal salt of at least one acidic organic compound, (B) at least one metal deactivator, and (C) at least one sulfur- and/or phosphorus-containing compound. These compositions are useful in providing lubricants and functional fluids with thermal stability and improved anti-wear, extreme-pressure, load-carrying and/or corrosion-inhibiting properties. Zinc-containing hydraulic fluids are widely accepted for numerous applications. These hydraulic fluids typically have excellent thermal stability and anti-wear properties due to the use therein of zinc-containing anti-wear agents. In recent years, however, there has been a growing concern about the accumulation in the workplace and environment of heavy metals such as zinc. This concern has led to a demand for hydraulic fluids containing ashless anti-wear agents. Ashless anti-wear agents are available, but hydraulic fluids based thereon typically lack sufficient thermal stability to be acceptable for many uses. The book "Lubricant Additives" by M.W. Ranney, published by Noyes Data Corporation of Parkridge, N.J. (1973), discloses a number of metal salts of various sulfonic and carboxylic acids and of phenols which are useful as detergent/dispersants in lubricating oil products. The book also entitled "Lubricant Additives" by C.V. Smallheer and R.K. Smith, published by the Lezius-Hiles Co. of Cleveland, Ohio (1967), similarly disclosed a number of detergent/dispersants including sulfonates, phenates and carboxylates which are useful as dispersants. U.S. Patent 4,100,082 discloses the use of neutral or basic metal salts of organic sulfur acids, carboxylic acids and phenols as detergent/dispersants for use in fuels and lubricants. U.S. Patent 4,627,928 discloses the use of basic magnesium salts of substituted aromatic hydroxy carboxylic acids as dispersants, detergents, antioxidants, etc., for lubricants and fuels. The use of triazoles such as benzotriazole as metal deactivators in lubricant compositions is disclosed in U.S. Patents 3,413,227; 4,162,225; 4,174,285; and 4,187,186. The use of phosphorus-containing amides as anti-wear agents for use in lubricant compositions is disclosed in U.S. Patents 4,032,461; 4,208,357; 4,282,171; and 4,670,169. The use of phosphorus-containing esters as anti-wear agents for use in lubricating compositions is disclosed in U.S. Patent 3,359,203. The use of such esters as E.P. agents in lubricant compositions is disclosed in U.K. Patent 1,347,845. Compositions prepared by the sulfurization of various organic materials including olefins are known in the art, and lubricants containing these compositions also are known. U.S. Patent 4,191,659 describes the preparation of sulfurized olefinic compounds by the catalytic reaction of sulfur and hydrogen sulfide with olefinic compounds containing from 3 to 30 carbon atoms. The compounds are reported to be useful in lubricating compositions, particularly those prepared for use as industrial gear lubricants. U.S. Patent 4,119,549 describes a similar procedure for sulfurizing olefins utilizing sulfur and hydrogen sulfide followed by removal of low boiling materials from said sulfurized mixture. Sulfur-containing compositions characterized by the presence of at least one cycloaliphatic group with at least two nuclear carbon atoms of one cycloaliphatic group or two nuclear carbon atoms of different cycloaliphatic groups joined together through a divalent sulfur linkage are described in U.S. Reissue Patent Re 27,331. The sulfur linkage contains at least two sulfur atoms, and sulfurized Diels-Alder adducts are illustrative of the compositions disclosed in the reissue patent. The sulfur-containing compositions are useful as extreme pressure and anti-wear additives in various lubricating oils. Dialdehydes containing disulfide groups and represented by the formula wherein both R groups are the same alkyl groups of 1 to 18 carbon atoms and both R¹ groups are the same alkyl or aryl groups are described in U.S. Patent 2,580,695. The compounds are reported to be useful as cross-linking agents and as chemical intermediates. Lubricating compositions containing sulfides having the formula wherein R₁ is a hydrocarbon group, R₂ is hydrogen or a hydrocarbon group, and x is 1 to 2 are described in U.S. Patent 3,296,137. Canadian Patent 1,168,222 discloses the use as additives for lubricants of the combination of (A) at least one benzotriazole or the reaction product of a benzotriazole with at least one aliphatic amine, and (B) at least one sulfurized aliphatic or alicyclic compound containing about 3-30 carbon atoms.

These compositions are useful as additives for lubricants and functional fluids; particularly hydraulic fluids, gear oils, greases and the like. Various preferred features and embodiments of the present invention will now be described by way of non-limiting example. As used in this specification and in the appended claims, the term "hydrocarbyl" denotes a group having a carbon atom directly attached to the remainder of the molecule and having a hydrocarbon or predominantly hydrocarbon character within the context of this invention. Such groups include the following: (1) Hydrocarbon groups; that is, aliphatic, (e.g., alkyl or alkenyl) , alicyclic (e.g., cycloalkyl or cycloalkenyl) , aromatic, aliphatic- and alicyclic-substituted aromatic, aromatic-substituted aliphatic and alicyclic groups, and the like, as well as cyclic groups wherein the ring is completed through another portion of the molecule (that is, any two indicated substituents may together form an alicyclic group) . Such groups are known to those skilled in the art. Examples include methyl, ethyl, octyl, decyl, octadecyl, cyclohexyl, phenyl, etc. (2) Substituted hydrocarbon groups; that is, groups containing non-hydrocarbon substituents which, in the context of this invention, do not alter the predominantly hydrocarbon character of the group. Those skilled in the art will be aware of suitable substituents. Examples include halo, hydroxy, nitro, cyano, alkoxy, acyl, etc. (3) Hetero groups; that is, groups which, while predominantly hydrocarbon in character within the context of this invention, contain atoms other than carbon in a chain or ring otherwise composed of carbon atoms. Suitable hetero atoms will be apparent to those skilled in the art and include, for example, nitrogen, oxygen and sulfur. In general, no more than about three substituents or hetero atoms, and preferably no more than one, will be present for each 10 carbon atoms in the hydrocarbyl group. Terms such as "alkyl-based", "aryl-based", and the like have meanings analogous to the above with respect to alkyl groups, aryl groups and the like. The term "hydrocarbon-based" has the same meaning and can be used interchangeably with the term hydrocarbyl when referring to molecular groups having a carbon atom attached directly to the remainder of a molecule. The term "lower" as used herein in conjunction with terms such as hydrocarbyl, alkyl, alkenyl, alkoxy, and the like, is intended to describe such groups which contain a total of up to 7 carbon atoms. The term "oil-soluble" refers to a material that is soluble in mineral oil to the extent of at least about one gram per liter at 25°C. Component (A): Component (A) is a neutral or basic metal salt, or boron-containing neutral or basic metal salt, of at least one acidic organic compound, the metal in said salt being selected from alkali metals, alkaline-earth metals, zinc, copper, aluminum or a mixture of two or more of said metals. The acidic organic compound from which these salts are derived are one or more carboxylic acids, sulfur-containing acids, phenols, or a mixture of two or more thereof. These acidic organic compounds are discussed in greater detail below. The term "basic" is a term of art which is generic to well known classes of metal salts. These basic metal salts have also been referred to as "overbased", "superbased", "hyperbased", "high-metal containing salts", and the like. Basic metal salts are characterized by a metal content in excess of that which would be present according to the stoichiometry of the metal and the particular acidic organic compound reacted with the metal, e.g., a sulfonic acid. Thus, if a monosulfonic acid, is neutralized with a basic metal compound, e.g., calcium hydroxide, the "neutral" or "normal" metal salt produced will contain one equivalent of calcium for each equivalent of acid, i.e., Processes for making such neutral and basic metal salts are well known in the art. Neutral salts can be made by heating a mineral oil solution of an acidic organic compound with a stoichiometric equivalent amount of a metal neutralizing agent such as the metal oxide, hydroxide, carbonate, bicarbonate, or sulfide at a temperature above about 50°C and filtering the resulting mass. Basic salts are similarly made with the exception that a stoichiometric excess of the metal is used. Also, a "promoter" in the neutralization step to aid the incorporation of the excess metal can be used in making the basic salts. Examples of compounds useful as the promoter include phenolic substances such as phenol, naphthol, alkylphenol, thiophenol, sulfurized alkylphenol, and condensation products of formaldehyde with a phenolic substance; alcohols such as methanol, 2-propanol, octyl alcohol, cellosolve, carbitol, ethylene glycol, stearyl alcohol, and cyclohexyl alcohol; and amines such as aniline, phenylenediamine, phenothiazine, phenyl-beta-naphthylamine, and dodecylamine. A particularly effective method for preparing the basic salts comprises mixing the acid organic compound with an excess of a basic metal neutralizing agent and at least one alcohol promoter, and carbonating the mixture at an elevated temperature such as 60-200°C. Component (A) typically has from 100% to 4000%, preferably from 100% to 3000%, more preferably from 100% to 2800%, more preferably from 200% to 1000% of the metal present in the corresponding neutral salt. In an advantageous embodiment, component (A) has from 110% to 4000%, preferably from 110% to 3000%, more preferably from 110% to 2800%, more preferably from 110% to 1000% of the metal present in the corresponding neutral salt. Preferred metals for the salts (A) include lithium, sodium, magnesium, calcium, potassium, barium, aluminum, zinc and copper. Mixtures of two or more of the foregoing metals can be used. Particularly preferred metals are sodium, magnesium, calcium or mixtures of two or more thereof. Carboxylic Acids : The carboxylic acids useful in making the salts (A) of the invention may be aliphatic or aromatic, mono-or polycarboxylic acid or acid-producing compounds. These carboxylic acids include lower molecular weight carboxylic acids (e.g., carboxylic acids having up to 18 carbon atoms such as fatty acids having 10 to 18 carbon atoms or tetrapropenyl-substituted succinic anhydride) as well as higher molecular weight carboxylic acids. Throughout this specification and in the appended claims, any reference to carboxylic acids is intended to include the acid-producing derivatives thereof such as anhydrides, esters, acyl halides, lactones and mixtures thereof unless otherwise specifically stated. The carboxylic acids of this invention are preferably oil-soluble and the number of carbon atoms present in the acid is important in contributing to the desired solubility of the salts (A). Usually, in order to provide the desired oil-solubility, the number of carbon atoms in the carboxylic acid should be at least 8 carbon atoms, more preferably at least 18 carbon atoms, more preferably at least 30 carbon atoms, more preferably at least 50 carbon atoms. Generally, these carboxylic acids do not contain more than 400 carbon atoms per molecule. The carboxylic acid may contain polar substituents provided that the polar substituents are not present in portions sufficiently large to alter significantly the hydrocarbon character of the carboxylic acid. Typical suitable polar substituents include halo, such as chloro and bromo, oxo, oxy, formyl, sulfenyl, sulfinyl, thio, nitro, etc. Such polar substituents, if present, preferably do not exceed 10% by weight of the total weight of the hydrocarbon portion of the carboxylic acid, exclusive of the carboxyl groups. The lower molecular weight monocarboxylic acids contemplated for use in this invention include saturated and unsaturated acids. Examples of such useful acids include dodecanoic acid, palmitic acid, decanoic acid, oleic acid, lauric acid, stearic acid, myristic acid, linoleic acid, linolenic acid, naphthenic acid, chlorostearic acid, tall oil acid, etc. Anhydrides and lower alkyl esters of these acids can also be used. Mixtures of two or more such agents can also be used. An extensive discussion of these acids is found in Kirk-Othmer "Encyclopedia of Chemical Technology" Third Edition, 1978, John Wiley & Sons New York, pp. 814-871. Examples of lower molecular weight polycarboxylic acids include dicarboxylic acids and derivatives such as sebacic acid, cetyl malonic acid, tetrapropylene-substituted succinic anhydride, etc. Lower alkyl esters of these acids can also be used. Lower molecular weight hydrocarbyl-substituted succinic acids and anhydrides can also be used. Typically, these compounds are represented, respectively, by the formulae wherein in Formulae II and III, R is a hydrocarbyl group of from 8 to 18 carbon atoms. Preferably, R is an aliphatic or alicyclic hydrocarbyl group with less than 10% of its carbon-to-carbon bonds being unsaturated. Examples of such groups include 4-butylcyclohexyl, di (isobutyl) , decyl, etc. The production of such substituted succinic acids and their derivatives via alkylation of maleic acid or its derivatives with a halohydrocarbon is well known to those of skill in the art and need not be discussed in detail herein. Acid halides of the afore-described lower molecular weight mono- and polycarboxylic acids can be used as lower molecular weight carboxylic acids in this invention. These can be prepared by the reaction of such acids or their anhydrides with halogenating agents such as phosphorus tribromide, phosphorus pentachloride, phosphorus oxychloride or thionyl chloride. Esters of such acids can be prepared simply by the reaction of the acid, acid halide or anhydride with an alcohol or phenolic compound. Particularly useful are the lower alkyl and alkenyl alcohols such as methanol, ethanol, allyl alcohol, propanol, cyclohexanol, etc. Esterification reactions are usually promoted by the use of alkaline catalysts such as sodium hydroxide or alkoxide, or an acidic catalyst such as sulfuric acid or toluene sulfonic acid. The monocarboxylic acids include isoaliphatic acids, i.e., acids having one or more lower acyclic pendant alkyl groups. Such acids often contain a principal chain having from 14 to 20 saturated, aliphatic carbon atoms and at least one but usually no more than four pendant acyclic alkyl groups. The principal chain of the acid is exemplified by groups derived from tetradecane, pentadecane, hexadecane, heptadecane, octadecane, and eicosane. The pendant group is preferably a lower alkyl group such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, n-hexyl, or other groups having up to 7 carbon atoms. The pendant group may also be a polar-substituted alkyl group such as chloromethyl, bromobutyl, methoxyethyl, or the like, but it preferably contains no more than one polar substituent per group. Specific examples of such isoaliphatic acids include 10-methyl-tetradecanoic acid, 11-methyl-pentadecanoic acid, 3-ethyl-hexadecanoic acid, 15-methyl-heptadecanoic acid, 16-methyl-hep-tadecanoic acid, 6-methyl-octadecanoic acid, 8-methyl-octadecanoic acid, 10-methyl-octadecanoic acid, 14-methyl-octadecanoic acid, 16-methyl-octadecanoic acid, 15-ethyl-heptadecanoic acid, 3-chloromethyl-nonadecanoic acid, 7,8,9,10-tetramethyl-octadecanoic acid, and 2,9,10-trimethyl-octadecanoic acid. The isoaliphatic acids include mixtures of branch-chain acids prepared by the isomerization of commercial fatty acids of, for example, 16 to 20 carbon atoms. A useful method involves heating the fatty acid at a temperature above 250°C and a pressure between 200 and 700 psi (1379-4826 kPa), distilling the crude isomerized acid, and hydrogenating the distillate to produce a substantially saturated isomerized acid. The isomerization can be promoted by a catalyst such as mineral clay, diatomaceous earth, aluminum chloride, zinc chloride, ferric chloride, or some other Friedel-Crafts catalyst. The concentration of the catalyst may be as low as 0.01%, but more often from 0.1% to 3% by weight of the isomerization mixture. Water also promotes the isomerization and a small amount, from 0.1% to 5% by weight, of water may thus be advantageously added to the isomerization mixture. The unsaturated fatty acids from which the isoaliphatic acids may be derived include oleic acid, linoleic acid, linolenic acid, and commercial fatty acid mixtures such as tall oil acids. The higher molecular weight mono- and polycarboxylic acids suitable for use in making the salts (A) are well known in the art and have been described in detail, for example, in the following U.S., British and Canadian patents: U.S. Patents 3,024,237; 3,087,936; 3,163,603; 3,172,892; 3,215,707; 3,219,666; 3,231,587; 3,245,910; 3,254,025; 3,271,310; 3,272,743; 3,272,746; 3,278,550; 3,288,714; 3,306,907; 3,307,928; 3,312,619; 3,341,542; 3,346,354; 3,367,943; 3,373,111; 3,374,174; 3,381,022; 3,394,179; 3,454,607; 3,346,354; 3,470,098; 3,630,902; 3,652,616; 3,755,169; 3,868,330; 3,912,764; 4,234,435; and 4,368,133; British Patents 944,136; 1,085,903; 1,162,436; and 1,440,219; and Canadian Patent 956,397. As disclosed in the foregoing patents, there are several processes for preparing these higher molecular weight carboxylic acids. Generally, these processes involve the reaction of (1) an ethylenically unsaturated carboxylic acid, acid halide, anhydride or ester reactant with (2) an ethylenically unsaturated hydrocarbon containing at least 18 aliphatic carbon atoms or a chlorinated hydrocarbon containing at least 18 aliphatic carbon atoms at a temperature within the range of 100-300°C. The chlorinated hydrocarbon or ethylenically unsaturated hydrocarbon reactant preferably contains at least 20 carbon atoms, more preferably at least 30 carbon atoms, more preferably at least 40 carbon atoms, more preferably at least 50 carbon atoms, and may contain polar substituents, oil-solubilizing pendant groups, and be unsaturated within the general limitations explained hereinabove. It is these hydrocarbon reactants which provide most of the aliphatic carbon atoms present in the acyl moiety of the final products. When preparing the higher molecular weight carboxylic acids, the carboxylic acid reactant usually corresponds to the formula R o -(COOH) n , where R o is characterized by the presence of at least one ethylenically unsaturated carbon-to-carbon covalent bond and n is an integer from 1 to 6 and preferably 1 or 2. The acidic reactant can also be the corresponding carboxylic acid halide, anhydride or ester. Ordinarily, the total number of carbon atoms in the acidic reactant will not exceed 20, preferably this number will not exceed 10 and generally will not exceed 6. Preferably the acidic reactant will have at least one ethylenic linkage in an alpha, beta-position with respect to at least one carboxyl function. Exemplary acidic reactants are acrylic acid, methacrylic acid, maleic acid, maleic anhydride, fumaric acid, itaconic acid, itaconic anhydride, citraconic acid, citraconic anhydride, mesaconic acid, glutaconic acid, chloromaleic acid, aconitic acid, crotonic acid, methylcrotonic acid, sorbic acid, 3-hexenoic acid, 10-decenoic acid, and the like. Preferred acid reactants include acrylic acid, methacrylic acid, maleic acid, and maleic anhydride. The ethylenically unsaturated hydrocarbon reactant and the chlorinated hydrocarbon reactant used in the preparation of these higher molecular weight carboxylic acids are preferably high molecular weight, substantially saturated petroleum fractions and substantially saturated olefin polymers and the corresponding chlorinated products. Polymers and chlorinated polymers derived from mono-olefins having from 2 to 30 carbon atoms are preferred. Especially useful polymers are the polymers of 1-mono-olefins such as ethylene, propene, 1-butene, isobutene, 1-hexene, 1-octene, 2-methyl-1-heptene, 3-cyclohexyl-1-butene, and 2-methyl-5-propyl-1-hexene. Polymers of medial olefins, i.e., olefins in which the olefinic linkage is not at the terminal position, likewise are useful. These are exemplified by 2-butene, 3-pentene, and 4-octene. Interpolymers of 1-mono-olefins such as illustrated above with each other and with other interpolymerizable olefinic substances such as aromatic olefins, cyclic olefins, and polyolefins, are also useful sources of the ethylenically unsaturated reactant. Such interpolymers include for example, those prepared by polymerizing isobutene with styrene, isobutene with butadiene, propene with isoprene, propene with isobutene, ethylene with piperylene, isobutene with chloroprene, isobutene with p-methyl-styrene, 1-hexene with 1,3-hexadiene, 1-octene with 1-hexene, 1-heptene with 1-pentene, 3-methyl-1-butene with 1-octene, 3,3-dimethyl-1-pentene with 1-hexene, isobutene with styrene and piperylene, etc. For reasons of oil solubility, the interpolymers contemplated for use in preparing the carboxylic acids of this invention are preferably substantially aliphatic and substantially saturated, that is, they should contain at least 80% and preferably 95%, on a weight basis, of units derived from aliphatic mono-olefins. Preferably, they will contain no more than 5% olefinic linkages based on the total number of the carbon-to-carbon covalent linkages present. In one embodiment of the invention, the polymers and chlorinated polymers are obtained by the polymerization of a C₄ refinery stream having a butene content of 35% to 75% by weight and an isobutene content of 30% to 60% by weight in the presence of a Lewis acid catalyst such as aluminum chloride or boron trifluoride. These polyisobutenes preferably contain predominantly (that is, greater than about 80% of the total repeat units) isobutene repeat units of the configuration. The chlorinated hydrocarbons and ethylenically unsaturated hydrocarbons used in the preparation of the higher molecular weight carboxylic acids can have number average molecular weights of up to 100,000 or even higher, although preferred higher molecular weight carboxylic acids have molecular weights up to 10,000, more preferably up to 7500, more preferably up to 5000. Preferred higher molecular weight carboxylic acids are those containing hydrocarbyl groups of at least 18 carbon atoms, preferably at least 30 carbon atoms, more preferably at least 40 carbon atoms, more preferably at least 50 carbon atoms. The higher molecular weight carboxylic acids may also be prepared by halogenating a high molecular weight hydrocarbon such as the above-described olefin polymers to produce a polyhalogenated product, converting the polyhalogenated product to a polynitrile, and then hydrolyzing the polynitrile. They may be prepared by oxidation of a high molecular weight polyhydric alochol with potassium permanganate, nitric acid, or a similar oxidizing agent. Another method involves the reaction of an olefin or a polar-substituted hydrocarbon such as a chloropolyisobutene with an unsaturated polycarboxylic acid such as 2-pentene-1,3,5-tricarboxylic acid prepared by dehydration of citric acid. Monocarboxylic acids may be obtained by oxidizing a monoalcohol with potassium permanganate or by reacting a halogenated high molecular weight olefin polymer with a ketene. Another convenient method for preparing monocarboxylic acid involves the reaction of metallic sodium with an acetoacetic ester or a malonic ester of an alkanol to form a sodium derivative of the ester and the subsequent reaction of the sodium derivative with a halogenated high molecular weight hydrocarbon such as brominated wax or brominated polyisobutene. Monocarboxylic and polycarboxylic acids can also be obtained by reacting chlorinated mono- and polycarboxylic acids, anhydrides, acyl halides, and the like with ethylenically unsaturated hydrocarbons or ethylenically unsaturated substituted hydrocarbons such as the polyolefins and substituted polyolefins described hereinbefore in the manner described in U.S. Patent 3,340,281. The monocarboxylic and polycarboxylic acid anhydrides can be obtained by dehydrating the corresponding acids. Dehydration is readily accomplished by heating the acid to a temperature above 70°C, preferably in the presence of a dehydration agent, e.g., acetic anhydride. Cyclic anhydrides are usually obtained from polycarboxylic acids having acid groups separated by no more than three carbon atoms such as substituted succinic or glutaric acid, whereas linear anhydrides are usually obtained from polycarboxylic acids having the acid groups separated by four or more carbon atoms. The acid halides of the monocarboxylic and polycarboxylic acids can be prepared by the reaction of the acids or their anhydrides with a halogenating agent such as phosphorus tribromide, phosphorus pentachloride, or thionyl chloride. Hydrocarbyl-substituted succinic acids and the anhydride, acid halide and ester derivatives thereof can be prepared by reacting maleic anhydride with a high molecular weight olefin or a chlorinated hydrocarbon such as a chlorinated polyolefin. The reaction involves merely heating the two reactants at a temperature in the range of 100°C to 300°C, preferably, 100°C to 200°C. The product from this reaction is a hydrocarbyl-substituted succinic anhydride wherein the substituent is derived from the olefin or chlorinated hydrocarbon. The product may be hydrogenated to remove all or a portion of any ethylenically unsaturated covalent linkages by standard hydrogenating procedures, if desired. The hydrocarbyl-substituted succinic anhydrides may be hydrolyzed by treatment with water or steam to the corresponding acid and either the anhydride or the acid may be converted to the corresponding acid halide or ester by reacting with a phosphorus halide, phenol or alcohol. Useful higher molecular weight hydrocarbyl-substituted succinic acids and anhydrides are represented by the formulae wherein in Formulae IIA and IIIA, R contains at least 18 carbon atoms, more preferably at least 30 carbon atoms, more preferably at least 40 carbon atoms, more preferably at least 50 carbon atoms. The number average molecular weight for R will generally not exceed 100,000, preferably it will not exceed 10,000, more preferably it will not exceed 7500, more preferably it will not exceed 5000. A group of carboxylic acid derivatives that are particularly useful in making the salts (A) of the invention are the lactones represented by the formula wherein in Formula IV, R¹, R², R³, R⁴, R⁵ and R⁶ are each independently H or hydrocarbyl groups of from 1 to about 30 carbon atoms; R² and R³ can be linked together to form an aliphatic or aromatic ring; and a is a number in the range of zero to 4. Within this group the lactones represented by the following formula are particularly useful wherein in Formula V, R⁷ and R⁸ are aliphatic hydrocarbyl groups of from 1 to 30 carbon atoms, a and b are numbers in the range of zero to 5 with the proviso that the sum of a and b does not exceed 5, and c is a number in the range of zero to 4. The procedures for preparing lactones of this type through intramolecular cyclization of hydroxy-containing carboxylic acids accompanied by the elimination of water are well known in the art. Generally, the cyclization is promoted by the presence of materials such as acetic anhydride, and the reaction is effected by heating the mixtures to elevated temperatures such as the reflux temperature while removing volatile materials including water. A preferred group of carboxylic acids useful in preparing the salts (A) of the present invention are the aromatic carboxylic acids. These acids can be represented by the formula wherein in Formula VI, R is an aliphatic hydrocarbyl group of preferably 4 to 400 carbon atoms, a is a number in the range of zero to 4, Ar is an aromatic group, X¹ and X² are independently sulfur or oxygen, and b is a number in the range of from 1 to 4, with the proviso that the sum of a and b does not exceed the number of unsatisfied valences of Ar. Preferably, R and a are such that there is an average of at least 8 aliphatic carbon atoms provided by the R groups in each compound represented by Formula VI. The aromatic group Ar in Formula VI may have the same structure as any of the aromatic groups Ar discussed below under the heading "Phenols". Examples of the aromatic groups that are useful herein include the polyvalent aromatic groups derived from benzene, naphthalene, anthracene, phenanthrene, indene, fluorene, biphenyl, and the like. Generally, the Ar groups used herein are polyvalent nuclei derived from benzene or naphthalene such as phenylenes and naphthylene, e.g., methylphenylenes, ethoxyphenylenes, nitrophenylenes, isopropylphenylenes, hydroxyphenylenes, mercaptophenylenes, N,N-diethylaminophenylenes, chlorophenylenes, dipropoxynaphthylenes, triethylnaphthylenes, and similar tri-, tetra-, pentavalent nuclei thereof, etc. These Ar groups may contain non-hydrocarbon substituents, for example, such diverse substituents as lower alkoxy, lower alkyl mercapto, nitro, halo, alkyl or alkenyl groups of less than 4 carbon atoms, hydroxy, mercapto, and the like. Examples of the R groups in Formula VI include butyl, isobutyl, pentyl, octyl, nonyl, dodecyl, docosyl, tetracontyl, 5-chlorohexyl, 4-ethoxypentyl, 4-hexenyl, 3-cyclohexyloctyl, 4-(p-chlorophenyl)-octyl, 2,3,5-trimethylheptyl, 4-ethyl-5-methyloctyl, and substituents derived from polymerized olefins such as polychloroprenes, polyethylenes, polypropylenes, polyisobutylenes, ethylene-propylene copolymers, chlorinated olefin polymers, oxidized ethylene-propylene copolymers, and the like. A group of useful carboxylic acids are those of the formula wherein in Formula VII, R, Ar, X¹, X², a and b are as defined in Formula VI, X³ is oxygen or sulfur, and c is a number in the range of 1 to 4, usually 1 to 2, with the proviso that the sum of a, b and c does not exceed the unsatisfied valences of Ar. Within this group, a useful class of carboxylic acids are those of the formula wherein in Formula VIII, R is an aliphatic hydrocarbyl group preferably containing from 4 to 400 carbon atoms, a is a number in the range of from zero to 4, preferably 1 to 3; b is a number in the range of 1 to 4, preferably 1 to 2, c is a number in the range of 1 to 4, preferably 1 to 2, and more preferably 1; with the proviso that the sum of a, b and c does not exceed 6. Preferably, R and a are such that the acid molecules contain at least an average of 12 aliphatic carbon atoms in the aliphatic hydrocarbon substituents per acid molecule. Also useful are the aliphatic hydrocarbon-substituted salicyclic acids wherein each aliphatic hydrocarbon substituent contains an average of at least 8 carbon atoms per substituent and 1 to 3 substituents per molecule. Salts prepared from such salicyclic acids wherein the aliphatic hydrocarbon substituents are derived from polymerized olefins, particularly polymerized lower 1-mono-olefins such as polyethylene, polypropylene, polyisobutylene, ethylene/propylene copolymers and the like and having average carbon contents of 30 to 400 carbon atoms are particularly useful. The aromatic carboxylic acids corresponding to Formulae VII and VIII above are well known or can be prepared according to procedures known in the art. Carboxylic acids of the type illustrated by these formulae and processes for preparing their neutral and basic metal salts are well known and disclosed, for example, in U.S. Patents 2,197,832; 2,197,835; 2,252,662; 2,252,664; 2,714,092; 3,410,798; and 3,595,791. Sulfur-Containing Acids : The sulfur-containing acids useful in making salts (A) of the invention include the sulfonic, sulfamic, thiosulfonic, sulfinic, sulfenic, partial ester sulfuric, sulfurous and thiosulfuric acids. Generally they are salts of carbocyclic or aliphatic sulfonic acids. The carbocyclic sulfonic acids include the mono- or polynuclear aromatic or cycloaliphatic compounds. The oil-soluble sulfonates can be represented for the most part by the following formulae: R¹ a -T-(SO₃) b (IX) R²-(SO₃) a (X) In the above Formulae IX and X, T is a cyclic nucleus such as, for example, benzene, naphthalene, anthracene, phenanthrene, diphenylene oxide, thianthrene, phenothioxine, diphenylene sulfide, phenothiazine, diphenyl oxide, diphenyl sulfide, diphenylamine, cyclohexane, petroleum naphthenes, decahydro-naphthalene, cyclopentane, etc.; R¹ is an aliphatic group such as alkyl, alkenyl, alkoxy, alkoxyalkyl, carboalkoxyalkyl, etc.; a is at least 1, and R¹ a +T contains a total of at least 15 carbon atoms. R² is an aliphatic hydrocarbyl group containing at least 15 carbon atoms. Examples of R² are alkyl, alkenyl, alkoxyalkyl, carboalkoxyalkyl, etc. Specific examples of R² are groups derived from petrolatum, saturated and unsaturated paraffin wax, and polyolefins, including polymerized C₂, C₃, C₄, C₅, C₆, etc., olefins containing from 15 to 7000 or more carbon atoms. The groups T, R¹, and R² in the above Formulae IX and X can also contain other inorganic or organic substituents in addition to those enumerated above such as, for example, hydroxy, mercapto, halogen, nitro, amino, nitroso, sulfide, disulfide, etc. In Formula IX, a and b are at least 1, and likewise in Formula X, a is at least 1. The following are specific examples of oil-soluble sulfonic acids within the scope of Formulae IX and X above, and it is to be understood that such examples serve also to illustrate the salts of such sulfonic acids useful in this invention. In other words, for every sulfonic acid enumerated it is intended that the corresponding neutral and basic metal salts thereof are also understood to be illustrated. Such sulfonic acids are mahogany sulfonic acids; bright stock sulfonic acids; sulfonic acids derived from lubricating oil fractions having a Saybolt viscosity from 100 seconds at 37.8°C (100°F) to 200 seconds at 98.9°C (210°F); petrolatum sulfonic acids; mono- and poly-wax-substituted sulfonic and polysulfonic acids of, e.g., benzene, naphthalene, phenol, diphenyl ether, naphthalene disulfide, diphenylamine, thiophene, alpha-chloronaphthalene, etc.; other substituted sulfonic acids such as alkyl benzene sulfonic acids (where the alkyl group has at least 8 carbons), cetylphenol mono-sulfide sulfonic acids, dicetyl thianthrene disulfonic acids, dilauryl beta naphthyl sulfonic acids, dicapryl nitronaphthalene sulfonic acids, and alkaryl sulfonic acids such as dodecyl benzene "bottoms" sulfonic acids. The latter are acids derived from benzene which have been alkylated with propylene tetramers or isobutene trimers to introduce 1, 2, 3, or more branched-chain C₁₂ substituents on the benzene ring. Dodecyl benzene bottoms, principally mixtures of mono- and di-dodecyl benzenes, are available as by-products from the manufacture of household detergents. Similar products obtained from alkylation bottoms formed during manufacture of linear alkyl sulfonates (LAS) are also useful in making the sulfonates used in this invention. The production of sulfonates from detergent manufactured by-products by reaction with, e.g., SO₃, is well known to those skilled in the art. See, for example, the article "Sulfonates" in Kirk-Othmer "Encyclopedia of Chemical Technology", Second Edition, Vol. 19, pp. 291 et seq. published by John Wiley & Sons, N.Y. (1969). Other descriptions of neutral and basic sulfonate salts and techniques for making them can be found in the following U.S. Patents: 2,174,110; 2,174,506; 2,174,508; 2,193,824; 2,197,800; 2,202,781; 2,212,786; 2,213,360; 2,228,598; 2,233,676; 2,239,974; 2,263,312; 2,276,090; 2,276,097; 2,315,514; 2,319,121; 2,321,022; 2,333,568; 2,333,788; 2,335,359; 2,337,552; 2,346,568; 2,366,027; 2,374,193; 2,383,319; 3,312,618; 3,471,403; 3,488,284; 3,595,790; and 3,798,012. Also included are aliphatic sulfonic acids such as paraffin wax sulfonic acids, unsaturated paraffin wax sulfonic acids, hydroxy-substituted paraffin wax sulfonic acids, hexapropylene sulfonic acids, tetra-amylene sulfonic acids, polyisobutene sulfonic acids wherein the polyisobutene contains from 20 to 7000 or more carbon atoms, chloro-substituted paraffin wax sulfonic acids, nitroparaffin wax sulfonic acids, etc.; cycloaliphatic sulfonic acids such as petroleum naphthene sulfonic acids, cetyl cyclopentyl sulfonic acids, lauryl cyclohexyl sulfonic acids, bis-(di-isobutyl) cyclohexyl sulfonic acids, mono- or poly-wax-substituted cyclohexyl sulfonic acids, etc. With respect to the sulfonic acids or salts thereof described herein and in the appended claims, it is intended herein to employ the term "petroleum sulfonic acids" or "petroleum sulfonates" to cover all sulfonic acids or the salts thereof derived from petroleum products. A useful group of petroleum sulfonic acids are the mahogany sulfonic acids (so called because of their reddish-brown color) obtained as a by-product from the manufacture of petroleum white oils by a sulfuric acid process. Generally neutral and basic salts of the above-described synthetic and petroleum sulfonic acids are useful in the practice of this invention. Other patents specifically describing techniques for making basic salts of the hereinabove-described sulfonic acids, carboxylic acids, and mixtures of any two or more of these include U.S. Patents 2,501,731; 2,616,904; 2,616,905; 2,616,906; 2,616,911; 2,616,924; 2,616,925; 2,617,049; 2,777,874; 3,027,325; 3,256,186; 3,282,835; 3,384,585; 3,373,108; 3,365,396; 3,342,733; 3,320,162; 3,312,618; 3,318,809; 3,471,403; 3,488,284; 3,595,790; and 3,629,109. Phenols : The phenols useful in making the salts (A) of the invention can be represented by the formula R a -Ar-(OH) b (XII) wherein in Formula XII, R is a hydrocarbyl group of from 4 to 400 carbon atoms; Ar is an aromatic group; a and b are each independently numbers of at least one, the sum of a and b being in the range of two up to the number of displaceable hydrogens on the aromatic nucleus or nuclei of Ar. Preferably, a and b are independently numbers in the range of 1 to 4, more preferably 1 to 2. R and a are preferably such that there is an average of at least about 8 aliphatic carbon atoms provided by the R groups for each phenol compound represented by Formula XII. While the term "phenol" is used herein, it is to be understood that this term is not intended to limit the aromatic group of the phenol to benzene. Accordingly, it is to be understood that the aromatic group as represented by "Ar" in Formula XII, as well as elsewhere in other formulae in this specification and in the appended claims, can be mononuclear such as a phenyl, a pyridyl, a thienyl, or polynuclear. The polynuclear groups can be of the fused type wherein an aromatic nucleus is fused at two points to another nucleus such as found in naphthyl, anthranyl, azanaphthyl, etc. The polynuclear group can also be of the linked type wherein at least two nuclei (either mononuclear or polynuclear) are linked through bridging linkages to each other. These bridging linkages can be chosen from the group consisting of carbon-to-carbon single bonds, ether linkages, keto linkages, sulfide linkages, polysulfide linkages of 2 to 6 sulfur atoms, sulfinyl linkages, sulfonyl linkages, alkylene linkages, alkylidene linkages, lower alkylene ether linkages, alkylene keto linkages, lower alkylene sulfur linkages, lower alkylene polysulfide linkages of 2 to 6 carbon atoms, amino linkages, polyamino linkages and mixtures of such divalent bridging linkages. In certain instances, more than one bridging linkage can be present in Ar between two aromatic nuclei; for example, a fluorene nucleus having two benzene nuclei linked by both a methylene linkage and a covalent bond. Such a nucleus may be considered to have three nuclei but only two of them are aromatic. Normally, however, Ar will contain only carbon atoms in the aromatic nuclei per se (plus any alkyl or alkoxy substituent present). The number of aromatic nuclei, fused, linked or both, in Ar can play a role in determining the integer values of a and b in Formula XII. For example, when Ar contains a single aromatic nucleus, the sum of a and b is from 2 to 6. When Ar contains two aromatic nuclei, the sum of a and b is from 2 to 10. With a tri-nuclear Ar moiety, the sum of a and b is from 2 to 15. The value for the sum of a and b is limited by the fact that it cannot exceed the total number of displaceable hydrogens on the aromatic nucleus or nuclei of Ar. The single ring aromatic nucleus which can be the Ar group can be represented by the general formula ar(Q) m wherein ar represents a single ring aromatic nucleus (e.g., benzene) of 4 to 10 carbons, each Q independently represents a lower alkyl group, lower alkoxy group, nitro group, or halogen atom, and m is 0 to 4. Halogen atoms include fluorine, chlorine, bromine and iodine atoms; usually, the halogen atoms are fluorine and chlorine atoms. Specific examples of when Ar is a single ring aromatic group include the following: etc., wherein Me is methyl, Et is ethyl, Pr is propyl, and Nit is nitro. When Ar is a polynuclear fused-ring aromatic group, it can be represented by the general formula wherein ar, Q and m are as defined hereinabove, m' is 1 to 4 and represent a pair of fusing bonds fusing two rings so as to make two carbon atoms part of the rings of each of two adjacent rings. Specific examples of when Ar is a fused ring aromatic group include: When the aromatic group Ar is a linked polynuclear aromatic group it can be represented by the general formula ar(Lng-ar) w (Q) mw wherein w is an integer of 1 to 20, ar is as described above with the proviso that there are at least two unsatisfied (i.e., free) valences in the total of ar groups, Q and m are as defined hereinbefore, and each Lng is a bridging linkage individually chosen from the group consisting of carbon-to-carbon single bonds, ether linkages (e.g., -O-), keto linkages (e.g., sulfide linkages (e.g., -S-), polysulfide linkages of 2 to 6 sulfur atoms (e.g., -S-₂₋₆), sulfinyl linkages (e.g., -S(O)-), sulfonyl linkages (e.g., -S(O)₂₋), lower alkylene linkages (e.g., -CH₂-, -CH₂-CH₂-, etc.), di(lower alkyl)-methylene linkages (e.g., CR°₂₋), lower alkylene ether linkages (e.g., -CH₂O-, -CH₂O-CH₂-, -CH₂-CH₂-O-, -CH₂CH₂OCH₂CH₂-, etc.), lower alkylene sulfide linkages (e.g., wherein one or more -O-'s in the lower alkylene ether linkages is replaced with an -S- atom), lower alkylene polysulfide linkages (e.g., wherein one or more -O-'s is replaced with a -S-₂₋₆ group), amino linkages (e.g., where alk is lower alkylene, etc.), polyamino linkages (e.g., where the unsatisfied free N valences are taken up with H atoms or R° groups), and mixtures of such bridging linkages (each R° being a lower alkyl group). It is also possible that one or more of the ar groups in the above-linked aromatic group can be replaced by fused nuclei such as ar ar m'. Specific examples of when Ar is a linked polynuclear aromatic group include: Usually all these Ar groups are unsubstituted except for the R and -O- groups (and any bridging groups). For such reasons as cost, availability, performance, etc., the Ar group is normally a benzene nucleus, lower alkylene bridged benzene nucleus, or a naphthalene nucleus. The R group in Formula XII is a hydrocarbyl group that is directly bonded to the aromatic group Ar. R preferably contains 6 to 80 carbon atoms, preferably 6 to 30 carbon atoms, more preferably 8 to 25 carbon atoms, and advantageously 8 to 15 carbon atoms. Examples of R groups include butyl, isobutyl, pentyl, octyl, nonyl, dodecyl, dodecosyl, tetracontyl, 5-chlorohexyl, 4-ethoxypentyl, 4-hexenyl, 3-cyclohexyloctyl, 4-(p-chlorophenyl)-octyl, 2,3,5-trimethylheptyl, 4-ethyl-5-methyloctyl, and substituents derived from polymerized olefins such as polychloroprenes, polyethylenes, polypropylenes, polyisobutylenes, ethylene-propylene copolymers, chlorinated olefin polymers, oxidized ethylene-propylene copolymers, propylene tetramer and tri(isobutene). The attachment of the hydrocarbyl group R to the aromatic group Ar can be accomplished by a number of techniques well known to those skilled in the art. One particularly suitable technique is the Friedel- Crafts reaction, wherein an olefin (e.g., a polymer containing an olefinic bond), or halogenated or hydrohalogenated analog thereof, is reacted with a phenol. The reaction occurs in the presence of a Lewis acid catalyst (e.g., boron trifluoride and its complexes with ethers, phenols, hydrogen fluoride, aluminium chloride, aluminum bromide, zinc dichloride, etc.). Methods and conditions for carrying out such reactions are well known to those skilled in the art. See, for example, the discussion in the article entitled, "Alkylation of Phenols" in "KirkOthmer Encyclopedia of Chemical Technology", Second Edition, Vol. 1, pages 894-895, Interscience Publishers, a division of John Wiley and Company, New York, 1963. Other equally appropriate and convenient techniques for attaching the hydrocarbyl group R to the aromatic group Ar will be apparent to those skilled in the art. As will be appreciated from inspection of Formula XII, the phenol group of the salt (A) of this invention contains at least one R group, as defined above, and OH. Each of the foregoing must be attached to a carbon atom which is a part of an aromatic nucleus in the Ar group. They need not, however, each be attached to the same aromatic ring if more than one aromatic nucleus is present in the Ar group. Boron-Containing Salts (A) : The boron-containing neutral or basic metal salts (A) of the invention are prepared by the process comprising reacting (1) at least one acidic organic compound or precursor thereof; (2) at least one metal-containing compound selected from alkali metals, alkaline earth metals, zinc, copper, aluminum or a mixture of two or more thereof; (3) at least one boron compound; and (4) at least one promoter. The acid organic compounds are any of the above-discussed carboxylic acids or acid-producing compounds, sulfur-containing acids, or phenols. The acid (1) can also be a mixture of two or more of these. The metal-containing compound (2) is preferably a metal oxide, metal hydroxide, metal halide, metal carbonate or metal borate. It can also be a mixture of two or more of the foregoing. Preferred metals for the metal-containing compounds (2) include lithium, sodium, magnesium, calcium, potassium, barium, aluminum, zinc and copper. Mixtures of two or more of the foregoing metals can be used. Particularly preferred metals are sodium, magnesium, calcium or mixtures of two or more thereof. The boron compounds (3) include boron oxide, boron oxide hydrate, boron trioxide, boron trifluoride, boron tribromide, boron trichloride, boron acids such as boronic acid (i.e., alkyl-B(OH)₂ or aryl-B(OH)₂), boric acid (i.e., H₃BO₃), tetraboric acid (i.e., H₂B₄O₇), metaboric acid (i.e., HBO₂), boron anhydrides, boron amides and various esters of such boron acids. The use of complexes of boron trihalide with ethers, organic acids, inorganic acids, or hydrocarbons is a convenient means of introducing the boron reactant into the reaction mixture. Such complexes are known and are exemplified by boron-trifluoride-triethyl ester, boron trifluoride-phosphoric acid, boron trichloride-chloroacetic acid, boron tribromide-dioxane, and boron trifluoride-methyl ethyl ether. Specific examples of boronic acids include methyl boronic acid, phenyl-boronic acid, cyclohexyl boronic acid, p-heptylphenyl boronic acid and dodecyl boronic acid. The boron acid esters include especially mono-, di-, and tri-organic esters of boric acid with alcohols or phenols such as, e.g., methanol, ethanol, isopropanol, cyclohexanol, cyclopentanol, 1-octanol, 2-octanol, dodecanol, behenyl alcohol, oleyl alcohol, stearyl alcohol, benzyl alcohol, 2-butyl cyclohexanol, ethylene glycol, propylene glycol, trimethylene glycol, 1,3-butanediol, 2,4-hexanediol, 1,2-cyclohexanediol, 1,3-octanediol, glycerol, pentaerythritol diethylene glycol, carbitol, Cellosolve, triethylene glycol, tripropylene glycol, phenol, naphthol, p-butylphenol, o,p-diheptylphenol, n-cyclohexylphenol, 2,2-bis-(p-hydroxyphenyl)propane, polyisobutene (molecular weight of 1500)-substituted phenol, ethylene chlorohydrin, o-chlorophenol, m-nitrophenol, 6-bromo-octanol, and 7-keto-decanol. Lower alcohols, 1,2-glycols, and 1-3-glycols, i.e., those having less than about 8 carbon atoms are especially useful for preparing the boric acid esters for the purpose of this invention. Methods for preparing the esters of boron acid are known and disclosed in the art (such as "Chemical Reviews," pp. 959-1064, Vol. 56). Thus, one method involves the reaction of boron trichloride with 3 moles of an alcohol or a phenol to result in a tri-organic borate. Another method involves the reaction of boric oxide with an alcohol or a phenol. Another method involves the direct esterification of tetra boric acid with 3 moles of an alcohol or a phenol. Still another method involves the direct esterification of boric acid with a glycol to form, e.g., a cyclic alkylene borate. The promoter (4) is a chemical employed to facilitate the incorporation of metal into the basic metal compositions. Among the chemicals useful as promoters are water, ammonium hydroxide, organic acids of up to 8 carbon atoms, nitric acid, sulfuric acid, hydrochloric acid, metal complexing agents such as alkyl salicylaldoxime, and alkali metal hydroxides such as lithium hydroxide, sodium hydroxide and potassium hydroxide, and mono- and polyhydric alcohols of up to 30 carbon atoms. Examples of the alcohols include methanol, ethanol, isopropanol, cyclohexanol, dodecanol, decanol, behenyl alcohol, ethylene glycol, diethylene glycol, triethylene glycol, monomethylether of ethylene glycol, trimethylene glycol, hexamethylene glycol, glycerol, pentaerythritol, benzyl alcohol, phenylethyl alcohol, sorbitol, nitropropanol, chloroethanol, aminoethanol, cinnamyl alcohol, allyl alcohol, and the like. Especially useful are the monohydric alcohols having up to about 10 carbon atoms and mixtures of methanol with higher monohydric alcohols. The boron-containing salts (A) are preferably formed by reacting the organic acid (1) with a portion of the metal-containing compound (2) to form a neutral metal salt of an organic acid. Additional metal-containing compound (2) is then added along with the boron compound (3) and promoter (4). The contents are heated to reflux and held at reflux for several hours. Preferred ratios of components (1), (2), (3) and (4) for the above reaction can be determined by the equation (wherein Eqs. means equivalent): This ratio is preferably in the range of about 0.2 to about 3, more preferably 0.5 to 2. For purposes of the above equation, one mole of boron is equal to the number of moles of the boron compound (3) times the number of borons present in that boron compound. Thus, if 3.2 moles of boric acid H₃BO₃ are used, then the number of moles of boron is 3.2 times 1 or 3.2. If 2 moles of tetraboric acid H₂B₄O₇ are used, the number of moles of boron is 2x4 or 8. For the purposes of the above equation, one equivalent of a metal is equal to the molecular weight of that metal divided by the valence of the metal ion. Thus, an equivalent weight of sodium is 23 (i.e., 23 divided by 1 = 23) while an equivalent weight of calcium is 20 (i.e., 40 divided by 2 = 20). The above reactions may be carried out in the presence of a substantially inert liquid solvent/diluent medium. This solvent/diluent medium desirably serves to maintain contact of the components and facilitates control of the reaction temperature. Examples of suitable solvent/diluent media include aliphatic and aromatic hydrocarbons such as benzene, toluene, naphtha, mineral oil, hexane, chlorinated hydrocarbons such as dichloro-benzene and heptylchloride, and ethers such as methyl n-amylether and n-butylether. Component (B) : The metal-deactivator (B) may be at least one benzotriazole which may be substituted or unsubstituted. In particular, suitable compounds are benzotriazole, alkyl-substituted benzotriazole (e.g., tolyltriazole, ethylbenzotriazole, hexylbenzotriazole, octylbenzotriazoles, etc.) aryl-substituted benzotriazole (e.g., phenylbenzotriazoles, etc.) , an alkaryl- or arylalkyl-substituted benzotriazole, and substituted benzotriazoles wherein the substituents may be hydroxy, alkoxy, halo (especially chloro), nitro, carboxy or carbalkoxy. Preferred are benzotriazole and the alkylbenzotriazoles in which the alkyl group contains 1 to 20 carbon atoms and especially 1 to 8 carbon atoms, most desirably benzotriazole and tolyltriazole. The metal deactivator (B) can also be the reaction product of at least one of the above benzotriazoles with at least one amine to form a nitrogen-containing composition. The amine can be one or more monoamines or polyamines. These monoamines and polyamines can be primary amines, secondary amines or tertiary amines. The amines can be aliphatic, cycloaliphatic, aromatic, or heterocyclic, including aliphatic-substituted cycloaliphatic, aliphatic-substituted aromatic, aliphatic-substituted heterocyclic, cycloaliphatic-substituted aliphatic, cycloaliphatic-substituted aromatic, cycloaliphatic-substituted heterocyclic, aromatic-substituted aliphatic, aromatic-substituted cycloaliphatic, aromatic-substituted heterocyclic-substituted alicyclic, and heterocyclic-substituted aromatic amines and may be saturated or unsaturated. The amines may also contain non-hydrocarbon substituents or groups as long as these groups do not significantly interfere with the reaction of the amines with the acylating reagents of this invention. Such non-hydrocarbon substituents or groups include lower alkoxy, lower alkyl mercapto, nitro, interrupting groups such as -O- and -S- (e.g., as in such groups as -CH₂CH₂-X-CH₂CH₂- where X is -O- or -S-). In general, the amine may be characterized by the formula wherein R₁, R₂ and R₃ are each independently hydrogen or hydrocarbyl, amino-substituted hydrocarbyl, hydroxy-substituted hydrocarbyl, alkoxy-substituted hydrocarbyl, amino, carbamyl, thiocarbamyl, guanyl and acylimidoyl groups. With the exception of the branched polyalkylene polyamine, the polyoxyalkylene polyamines, and the high molecular weight hydrocarbyl-substituted amines described more fully hereafter, the amines ordinarily contain less than 40 carbon atoms in total and usually not more than 20 carbon atoms in total. Aliphatic monoamines include mono-, di- and tri-aliphatic-substituted amines wherein the aliphatic groups can be saturated or unsaturated and straight or branched chain. Such amines include, for example, mono-, di- and tri-alkyl-substituted amines; mono-, di-and tri-alkenyl-substituted amines; and amines having one or more N-alkenyl substituents and one N-alkyl substituents and the like. The total number of carbon atoms in these aliphatic monoamines will, as mentioned before, normally not exceed 40 and usually not exceed 20 carbon atoms. Specific examples of such monoamines include ethylamine, diethylamine, triethylamine, n-butylamine, di-n-butylamine, tri-n-butylamine, allylamine, isobutylamine, cocoamine, stearylamine, laurylamine, methyllaurylamine, oleylamine, N-methyloctylamine, dodecylamine, octadecylamine, and the like. Examples of cycloaliphatic-substituted aliphatic amines, aromatic-substituted aliphatic amines, and heterocyclic-substituted aliphatic amines, include 2-(cyclohexyl)ethylamine, benzylamine, phenethylamine, and 3-(furylpropyl)amine. Cycloaliphatic monoamines are those monoamines wherein there is one cycloaliphatic substituent attached directly to the amino nitrogen through a carbon atom in the cyclic ring structure. Examples of cycloaliphatic monoamines include cyclohexylamines, cyclopentylamines, cyclohexenylamines, cyclopentenylamines, N-ethyl-cyclohexylamine, dicyclohexylamines, and the like. Examples of aliphatic-substituted, aromatic-substituted, and heterocyclic-substituted cycloaliphatic monoamines include propyl-substituted cyclohexylamines, phenyl-substituted cyclopentylamines, and pyranyl-substituted cyclohexylamine. Aromatic amines include those monoamines wherein a carbon atom of the aromatic ring structure is attached directly to the amino nitrogen. The aromatic ring will usually be a mononuclear aromatic ring (i.e., one derived from benzene) but can include fused aromatic rings, especially those derived from naphthalene. Examples of aromatic monoamines include aniline, di-(para-methylphenyl)amine, naphthylamine, N-(n-butyl)-aniline, and the like. Examples of aliphatic-substituted, cycloaliphatic-substituted, and heterocyclic-substituted aromatic monoamines are para-ethoxyaniline, para-dodecylaniline, cyclohexyl-substituted naphthylamine, and thienyl-substituted aniline. The polyamines include principally alkylene amines conforming for the most part to the formula wherein n is a number preferably less than about 10, each R is independently a hydrogen group or a hydrocarbyl group preferably having up to 30 carbon atoms, and the alkylene group is preferably a lower alkylene group having less than 8 carbon atoms. The alkylene amines include principally methylene amines, ethylene amines, butylene amines, propylene amines, pentylene amines, hexylene amines, heptylene amines, octylene amines, other polymethylene amines. They are exemplified specifically by: ethylene diamine, triethylene tetramine, propylene diamine, decamethylene diamine, octamethylene diamine, di(heptamethylene) triamine, tripropylene tetramine, tetraethylene pentamine, trimethylene diamine, pentaethylene hexamine, di-(trimethylene) triamine. Higher homologues such as are obtained by condensing two or more of the above-illustrated alkylene amines likewise are useful. The ethylene amines are especially useful. They are described in some detail under the heading "Ethylene Amines" in Encyclopedia of Chemical Technology, Kirk and Othmer, Vol. 5, pp. 898-905, Interscience Publishers, New York (1950). Such compounds are prepared most conveniently by the reaction of an alkylene chloride with ammonia. The reaction results in the production of somewhat complex mixtures of alkylene amines, including cyclic condensation products such as piperazines. These mixtures find use in the process of this invention. On the other hand, quite satisfactory products may be obtained also by the use of pure alkylene amines. An especially useful alkylene amine for reasons of economy as well as effectiveness of the products derived therefrom is a mixture of ethylene amines prepared by the reaction of ethylene chloride and ammonia and having a composition which corresponds to that of tetraethylene pentamine. Hydroxyalkyl-substituted alkylene amines, i.e., alkylene amines having one or more hydroxyalkyl substituents on the nitrogen atoms, likewise are contemplated for use herein. HIgher homologues such as are obtained by condensation of the above illustrated alkylene amines or hydroxy alkyl-substituted alkylene amines through amino radicals or through hydroxy radicals are likewise useful. It will be appreciated that condensation through amino radicals results in a higher amine accompanied with removal of ammonia and that condensation through the hydroxy radicals results in products containing ether linkages accompanied with removal of water. The metal deactivator (B) can also be the reaction product of at least one of the above benzotriazoles with at least one nitrogen-containing ashless dispersant of the type described below under the heading "Lubricants and Functional Fluids". Particularly preferred are the nitrogen-containing carboxylic dispersants, amine dispersants and Mannich dispersants described below. The benzotriazole-amine and benzotriazole-ashless dispersant reaction products may be prepared by merely blending the reagents and allowing the reaction to proceed. The reaction may be effected in a substantially inert, normally liquid organic diluent (which may be the oil or diluent constituent of the lubricant or concentrate containing the composition of this invention) such as mineral oil, benzene, toluene, xylene, petroleum naphtha, an aliphatic ether or the like, whereupon it may take place at a temperature as low as 15°C. Ordinarily, it is preferred to carry out the reaction at temperatures of up to 160°C, with temperatures in the range of 60°C to 140°C being useful. The proportions of the benzotriazole and amine or ashless dispersant used for the preparation of the reaction products useful as component (B) may vary widely. In general, it is preferred to incorporate as much of the benzotriazole as possible in an oil-dispersible medium and this can be done by using about one equivalent of amine or ashless dispersant per equivalent of benzotriazole. (The equivalent weight of the amine or ashless dispersant is its molecular weight divided by the number of basic nitrogen atoms therein, and that of the benzotriazole is its molecular weight divided by the number of triazole rings therein.) In some instances, however, it may be desirable to use more or less than one equivalent of amine or ashless dispersant per equivalent of benzotriazole. The precise molecular structures of the benzotriazole-amine and benzotriazole-ashless dispersant reaction products are not known with certainty and are not critical. It is believed, however, that the benzotriazoles are generally more acidic than the amines or ashless dispersants and thus the compositions may comprise amine salts of the benzotriazoles. Phosphorus-Containing Amides (C-1) : The phosphorus-containing amides (C-1) comprise at least one compound represented by the formula: wherein in Formula XIII: X¹, X², X³, X⁴ and X⁵ are each independently oxygen or sulfur; R¹ and R² are each independently hydrocarbyl groups; R³, R⁴, R⁵, R⁶ and R⁷ are each independently hydrogen, halogen or hydrocarbyl groups; a and b are independently zero or 1; n is zero or 1; n' is 1, 2 or 3; with the proviso that: (1) when n' is 1, R⁸ is hydrogen, -R, -ROH, -ROR, -RSR or (2) when n' is 2, R⁸ is a coupling group selected from -R-, -R*-, -R-O-R-, -R-S-R-, and (3) when n' is 3, R⁸ is the coupling group wherein each R is independently a hydrocarbyl group of 1 to 12 carbon atoms; and R* is a hydrocarbyl or carboxyhydrocarbyl group of 1 to 60 carbon atoms. X¹, X² and X⁵ are preferably oxygen. X³ and X⁴ are preferably sulfur. R¹ and R² are each independently hydrocarbyl groups of from 1 to 50 carbon atoms, more preferably from 1 to 30 carbon atoms, more preferably from 3 to 18 carbon atoms, more preferably from 4 to 8 carbon atoms.

R³, R⁴, R⁵, R⁶ and R⁷ are each independently hydrogen or hydrocarbyl groups of 1 to 50 carbon atoms, more preferably 1 to 30 carbon atoms, more preferably 1 to 18 carbon atoms, more preferably 1 to 8 carbon atoms. Advantageously, R³, R⁴, R⁵, R⁶ and R⁷ are independently hydrogen; alkyl groups of from 1 to 22 carbon atoms; cycloalkyl groups of from 4 to 22 carbon atoms; or aromatic, alkyl substituted aromatic or aromatic-substituted alkyl groups of from 4 to 34 carbon atoms. When R is a linking group, it is preferably methylene. R* is preferably an alkylene or alkylidene group of 1 to 28 carbon atoms. The phosphorous-containing amides represented by Formula XIII can be made by various alternative routes. In one embodiment, the preparation of these amides involves the reaction of a phosphorous-containing acid reactant having the formula with an acrylamide-type reactant having the formula wherein the various R and X groups are as set forth above in Formula XIII. The reactant (A) is described above under the heading "Phosphorus-Containing Acids". Examples of reactant (B) include acrylamide, methacrylamide wherein R⁵ is methyl, and crotonamide. The reaction between the reactants (A) and (B) is exothermic and hence only slight heat need be applied thereto. The reaction conveniently can be carried out in an inert atmosphere such as nitrogen at from 25°C to 100°C, with from 70°C to 90°C being preferred. The reaction can be carried out in the presence or absence of a solvent. Preferably, the reaction takes place in a solvent medium which typically is a hydrocarbon such as toluene, xylene, hexane, heptane, kerosene, fuel oil, an oil of a lubricating viscosity, and the like or a chlorohydrocarbon such as chloroform, carbon tetrachloride, and the like, or an alcohol such as methanol, ethanol, propanol, butanol, 2-ethylhexanol, and the like. The solvent, in addition to acting as such, preferably imparts favourable processing characteristics such as controlling the exothermic reaction as well as preventing unwanted side reactions. The reaction time, while dependent upon temperature, is usually as short as one or two hours or less. The reaction between the reactants (A) and (B) yields a compound having the formula At this point the R⁸ group of Formula XIII is hydrogen and n is 1. This reaction product XIV is an intermediate. However, it can also serve as an end product for use as the additive (C-1) of the invention. This product is useful in providing lubricants and functional fluids with enhanced load-carrying, extreme pressure, anti-wear and/or corrosion-inhibiting properties. The intermediate reaction product XIV can be coupled in a manner such as described below and/or further reacted in various ways known to those skilled in the art to include other functional groups R⁸ on the nitrogen atom which groups include -ROH, -ROR, -RSR, wherein R is as defined above with respect to Formula XIII. In another embodiment of the invention, the preparation of the phosphorus-containing amides XIII involves reacting reactant (A) with a compound having the formula wherein the various R and X groups and n′ are as set forth in Formula XIII. Reactant (D) is similar to reactant (B) except that it is coupled by an R⁸ coupling group (i.e., one of the above-indicated groups for R⁸ when n′=2 or 3). Accordingly, the definition of R³, R⁴, R⁵ and R⁷ is the same as set forth hereinabove with respect to reactant (B). R⁸ is the same as discussed above with respect to Formula XIII, when n′= 2 or 3, with n′ preferably being 2 and R⁸ preferably being -CH₂-O- CH₂-. The reaction between the reactants (A) and (D) is exothermic and thus requires only a slight amount of heat. It is preferably carried out in an inert atmosphere at a temperature from 25°C to 100°C with from 70°C to 90°C being preferred. The reaction time is generally short, for example, on the order of less than an hour or two. Hydrocarbon solvents such as toluene, xylene, hexane, heptane, kerosene, fuel oil, an oil of a lubricating viscosity, and the like or chlorinated hydrocarbon such as chloroform, carbon tetrachloride, and the like, or an alcohol such as methanol, ethanol, propanol, butanol, 2-ethylhexanol, and the like, can be used. Once the product has been formed, the various solvents can be removed by stripping under a vacuum and the like. Another alternative method of preparing the phosphorus-containing amides of Formula XIII and especially the coupled compounds set forth hereinabove containing an R⁶ group is via a displacement reaction. In this reaction, a metal salt of the reactant (A) is used. That is a metal salt according to the following formula is reacted with a compound of the formula wherein X¹, X², X³, X⁴, X⁵, R¹, R², R³, R⁴, R⁵, R⁶, R⁷ and n are the same as set forth above with respect to Formula XIII. M is an alkali metal (e.g., sodium, potassium and the like) or an alkaline-earth metal (e.g., manganese, calcium and the like) or hydrogen, with sodium and potassium being preferred. X⁶ is a displaceable halogen or carbon group such as Cl, Br, I, tosyl, mesyl, and the like. The reaction between reactants A′ and F proceeds in a manner very similar to that set forth above with regard to the reaction product between reactants (A) and (B). Briefly, the reaction is carried out at a temperature of 10°C to 200°C with from 50°C to 150°C being preferred. An inert atmosphere such as nitrogen is used. Although not required, the reaction can take place in a menstruum. The solvent also renders by-product salts (e.g., KCl, NaCl, NaBr, KBr, etc.) insoluble in the reaction medium and which can be removed by filtration. The amounts of reactants A′ and F are generally equivalent amounts. The resulting product has the formula The reaction product formed by the reaction between reactants (A) and (B) can be coupled by reacting it with a coupling agent (C) which is an aldehyde or ketone (or a reaction synthon equivalent of an aldehyde or ketone) of the formula wherein R⁹ and R¹⁰ are each independently hydrogen, alkyl groups of 1 to 12 carbon atoms, phenyl, or alkyl-substituted phenyl having from 7 to 12 carbon atoms. Preferably, coupling agent (C) is an aldehyde (i.e., R¹⁰ is H) having a total of 1 to 3 carbon atoms therein with one carbon atom being preferred. Formaldehyde and paraformaldehyde are preferred; these can result in methylene and dimethylene ether coupling groups. The coupling reaction preferably takes place in the presence of a strong mineral or organic acid catalyst such as HCl, H₂SO₄, H₄PO₄, CH₃SO₃H, p-toluenesulfonic acid, and the like. The amount of the acid catalyst is generally from 0.3 to 1.5% by weight, preferably from 0.8 to 1.2%, and more preferably from 0.9 to 1.1% by weight based upon the weight of the total product formed. Although lesser amounts of catalyst can be utilized, the reaction is generally slower and a smaller fraction of the desired product is formed. The reaction with coupling agent (C) preferably takes place at an initial temperature of from 80°C to 120°C, more preferably from 80°C to 100°C in an inert atmosphere. The final reaction temperature is generally higher as from 100°C to 150°C and preferably from 125°C to 135°C. If it is desired to stop the reaction at the carbinol stage. (Formula XV where X⁵ is oxygen) the reaction between (A) and (B) is preferably carried out using basic catalysts (i.e., NaHCO₃, KHCO₃, Na₂CO₃, KCO₃, NaOH, KOH, etc.). This reaction mixture can be neutralized with acid and heated to remove water; reacted with H₂S, NaHS or NA₂S or other source of S=; or, NH₃ or R″NH₂ where R″ is alternatively H, alkyl of 1 to about 60 carbon atoms, aryl, alkyl-substituted, aryl or aryl-substituted alkyl of 6 to 30 carbon atoms or acyl of 1 to 22 carbon atoms. The ratio of reactant (A) and to reactant (B) that is employed is preferably a 1:1 equivalent weight ratio although greater or lesser amounts can be utilized. A 1:1 equivalent weight ratio of the two reactants is preferable in that otherwise a higher acid number is obtained than desired or one of the reactants is wasted. The amount of reaction product formed and reacted with coupling agent (C) is from 0.3 to 3 weight equivalents of reaction product per weight equivalent of said coupling agent (C) with a 1:1 equivalent ratio being preferred. The coupling agent (C) may be a mixture of different couplers and preferably includes paraformaldehyde. The combination of formaldehyde and phosphorus containing amide compound as described above may couple two amides or may result in the formation of a -CH₂OH on the nitrogen atom of the amide. Two of such amides with a -CH₂OH group thereon may then be reacted to form a coupled amide with the coupling group being Such a coupling reaction may take place during use of such uncoupled compounds which reaction is endothermic. The endothermic reaction may be beneficial to the load-carrying lubricating properties of the overall oil composition. Other couplers (R⁸ in Formula XIII when n' is 2 or 3) and functional groups (R⁸ in Formula XIII when n' is 1) can be attached to the nitrogen atoms of the phosphorus-containing amides described above by procedures known to those skilled in the art. Phosphorus-Containing Esters (C-2) : The nonmetal-containing phosphorus-containing esters (C-2) of the present invention are characterized by the structural formula wherein in Formula XVI, X¹, X², X³ and X⁴ each are independently oxygen or sulfur; R¹ and R² are each independently hydrocarbyl groups; R³, R⁴ and R⁵ are each independently hydrogen or hydrocarbyl groups; R⁶ is a hydrocarbyl group; and a and b are each independently zero or 1.

The phosphorus-containing esters represented by Formula XVI can be prepared by the reaction of the phosphorus-containing acid. with a compound represented by the formula wherein the various R and X groups are as defined with respect to Formula XVI. Reactant (A) is described above under the heading "Phosphorus-Containing Acids". Reactant (B) may be prepared by the reaction of an alcohol represented by the formula R⁶OH with an alpha, beta-unsaturated carboxylic acid represented by the formula wherein R³, R⁴ and R⁵ are as defined above with respect to Formula XVI. The reaction between reactants (A) and (B) can be carried out by adding over a period of time either reactant (A) or (B) to the other with stirring preferably in the presence of an inert organic solvent, such as benzene, toluene or methylene chloride. The addition is preferably carried out at an elevated temperature, for instance at reflux. The reaction mixture is then refluxed over a further period of time, for instance from 1 to 4 hours. The product is then cooled and neutralized, for instance by washing with aqueous sodium carbonate and then, if desired, with brine. The solvent is then removed by evaporation and then, if desired, the product is steam-distilled. The product may afterwards be purified by conventional techniques, for instance by filtering. Sulfur-Coupled Dithiocarbamates (C-3) : The sulfur-coupled dithiocarbamates (C-3) of the present invention are characterized by the structural formula wherein in Formula XVII, R¹, R² and R³ are each independently H or a hydrocarbyl group; R⁴ is H, OH or a hydrocarbyl group; R⁵ and R⁶ are each independently H, a hydrocarbyl group or hydroxyhydrocarbyl group; or R³ and R⁴ together and/or R⁵ and R⁶ together and/or R¹ and R³ together and/or R² and R⁴ together may form cyclic groups, and x is a number from 1 to 8. The hydrocarbyl groups of R¹ through R⁴ may be straight-chain or branched-chain hydrocarbyl groups. Each of R¹ through R⁶ may independently contain from 1 to 100 carbon atoms, preferably from 1 to 30 carbon atoms. The groups R¹ through R⁴ may be aliphatic or aromatic groups such as alkyl, cycloalkyl, alkaryl, aralkyl or aryl groups. R³ and R⁴ together and/or R⁵ and R⁶ together may be alkylene groups containing from about 4 to 7 carbon atoms. In these embodiments, R³ and R⁴ together with the carbon atom bonded to R³ and R⁴ in Formula XVII will form a cycloalkyl group, and R⁵ and R⁶, together with the nitrogen atom bonded to R⁵ and R⁶ in Formula XVII forms a heterocyclic group. Specific examples of hydrocarbyl groups R¹ through R⁶ include methyl, ethyl, isopropyl, isobutyl, secondary butyl, cyclohexyl, cyclopentyl, octyl, dodecyl, octadecyl, eicosyl, behenyl, triacontonyl, phenyl, naphthyl, phenethyl, octylphenyl, tolyl, xylyl, dioctadecylphenyl, triethylphenyl, chlorophenyl, methoxyphenyl, dibromophenyl, nitrophenyl, 3-chlorohexyl, etc. In one embodiment of the present invention, the sulfur-coupled dithiocarbamate is characterized by the structural formula S x ( CH(R³)-CH(R⁴)S(S)CNR⁵R⁶)₂ (XVII-A) wherein in Formula XVII-A, x is a number of from 1 to 2, R³ and R⁴ are hydrogen or a hydrocarbyl group, and R⁵ and/or R⁶ are each individually hydrocarbyl groups. The hydrocarbyl groups in Formula XVII-A may be any of the hydrocarbyl groups described above with respect to Formula XVII. Generally, R⁵ and R⁶ will contain from 1 to 50 carbon atoms, and R³ and R⁴ are hydrocarbyl groups containing from 1 to 100 carbon atoms. In another embodiment of the present invention, the dithiocarbamates are characterized by the structural formula wherein in Formula XVII-B, R¹, R², R³, R⁵, R⁶ and x are as defined above with respect to Formula XVII. In one embodiment the sulfur-coupled dithiocarbamates are prepared by a process comprising the steps of (A) reacting a sulfur halide with about a stoichiometric equivalent of (i) at least one olefinic hydrocarbon or (ii) an aldehyde or ketone at a temperature and for a period of time sufficient to produce a di(halohydrocarbyl)sulfur intermediate or dialdehyde or diketo sulfur intermediate, and (B) reacting the intermediate with a salt of a dithiocarbamate in an amount sufficient generally to replace both halo groups with the dithiocarbamate groups or to react with both carbonyl groups of the dialdehyde or diketone. When the starting material is (i) at least one olefinic hydrocarbon, the resulting product is characterized by either Formula XVII or Formula XVII-A or the product is a mixture comprising principally materials characterized by Formulae XVII and XVII-A. When the starting material is (ii) an aldehyde or a ketone, the product is characterized primarily by Formula XVII-B. The sulfur halide utilized in the first step (A) may be sulfur monochloride (i.e., S₂Cl₂), sulfur dichloride, sulfur monobromide, sulfur dibromide, or mixtures of any of the above sulfur halides with elemental sulfur in varying amounts. Various olefins and olefin mixtures may be used as the starting material in step (A). Olefin mixtures resulting from the oligomerization of ethylene and/or propylene are available at low cost. The olefinic hydrocarbons contain at least one olefinic double bond which is defined as a non-aromatic double bond. That is, the double bond connects two aliphatic carbon atoms. In its broadest sense, the olefin may be defined by the formula R¹R³C=CR²R⁴ wherein each of R¹, R², R³ and R⁴ is hydrogen or a hydrocarbyl group as defined above with respect to Formulae XVII, XVII-A or XVII-B. Although diolefinic hydrocarbons may be utilized, it is preferred that the olefin be a monoolefin and the olefin may be a terminal monoolefinic hydrocarbon; that is, those olefins in which R¹ and R³ are hydrogen and R² and/or R⁴ are alkyl or aryl. Internal olefinic compounds, e.g., where R¹ and R² are alkyl or aryl groups also are useful. Olefinic compounds containing 3 to 100 carbon atoms and more generally from 3 to 30 carbon atoms are particularly desirable. Isobutene, propylene, and their dimers, trimers, tetramers, etc. and mixtures thereof are also useful olefinic compounds. Of these compounds, isobutylene, diisobutylene, triisobutylene and tetraisobutylene are particularly desirable because of their availability. The product which is obtained from the reaction of a sulfur halide with one or more of the above-identified olefinic hydrocarbons is a di(halohydrocarbyl)sulfide intermediate produced by the addition of the elements of the sulfur halide to the unsaturated carbon atoms of the olefin. The reaction proceeds on mixing of the olefin and the sulfur halide although the rate of the reaction is increased by elevating the temperature of the mixture. Thus, the mixture generally is between -20°C and 120°C until the reaction is completed. The reaction temperature is dictated by the reactivity of the starting olefin and the thermal stability of the reaction product. Alternatively, the olefin can be warmed to the desired temperature whereupon the sulfur halide can be added dropwise, generally in an inert atmosphere at a rate sufficient to maintain the desired temperature. Following the completion of the addition of the sulfur halide, the reaction mixture may be heated for an extended period to complete the reaction. The amount of sulfur halide reacted with the olefinic hydrocarbon generally is a stoichiometric equivalent. For example, when a sulfur monohalide is utilized as the sulfur halide source, one mole of sulfur monohalide is reacted with two moles of the olefin or olefin mixture. Catalysts or reaction promoters may be utilized although they are generally found to be unnecessary. Examples of such catalysts or promoters include the lower aliphatic amines and aromatic amines, especially tertiary amines. The aldehydes or ketones which may be utilized as a starting material for reaction with a sulfur halide may be characterized by the following formula R¹R³CHC(O)R² wherein R¹, R² and R³ are each individually hydrogen or hydrocarbyl groups as defined above with respect to Formulae XVII, XVII-A or XVII-B. When the starting material is an aldehyde, the intermediate will contain two aldehyde carbonyl groups, and when the starting material is a ketone, the sulfur intermediate will contain two keto groups. The aldehydes and ketones may be reacted with sulfur halides such as sulfur monochloride, sulfur dichloride, sulfur monobromide, sulfur dibromide, and mixtures of sulfur halide with elemental sulfur. The reaction of an aldehyde or ketone with a sulfur halide may be effected simply by mixing the two reactants at the desired temperature which may range from -30°C to 250°C or higher. A preferred reaction temperature generally is within the range of from 10 to 80°C. The reaction may be carried out in the presence of a diluent or solvent such as benzene, naphtha, hexane, carbon tetrachloride, chloroform, mineral oil, etc. The diluent/solvent facilitates the control of the reaction temperature and a thorough mixing of the the reactants. The relative amounts of the aldehyde or ketone and the sulfur halide may vary over wide ranges. In most instances, the reaction involves two moles of the aldehyde or ketone and one mole of the sulfur halide. In other instances, an excess of either one of the reactants may be used. When sulfur compounds are desired which contain more than two sulfur atoms, (e.g., x is an integer from 3-8) these compounds can be obtained by reacting the aldehydes and ketones with a mixture of sulfur halide and sulfur. This is usually accomplished by reacting the sulfur halide and sulfur prior to reaction with the aldehyde or ketone. Specific examples of aldehydes that can be reacted with sulfur halides include, for example acetaldehyde, propionaldehyde, butyraldehyde, isobutyraldehyde, 2-ethyl-1-hexaldehyde, cyclohexanecarboxaldehyde (C₆H₁₁CHO). Examples of ketones include dimethylketone, methylethylketone, diethylketone, methylisopropylketone, methylisobutylketone, etc. The sulfur-coupled dithiocarbamates of the present invention are prepared by reacting the above-described sulfur intermediates with a salt of a dithiocarbamate in an amount sufficient to replace the halo groups with dithiocarbamate groups or to react with both carbonyl groups of the dialdehyde or diketone intermediate. The dithiocarbamate salts may be represented by the formula R⁵R⁶NC(S)SX wherein R⁵ and R⁶ are each individually hydrogen, hydrocarbyl, or hydroxyhydrocarbyl groups and X is an alkali metal, tertiary amine, or other basic material. The salts of the dithiocarbamic acids may be prepared by the reaction of an amine R⁵R⁶NH with carbon disulfide in the presence of a base, usually an alkali metal hydroxide, generally, at a molar ratio of 1:1:1. Preferably the base is an alkali metal hydroxide such as sodium or potassium hydroxide, and more generally, sodium hydroxide. However, the base can be a tertiary amine or in excess of the amine being used on the reaction. The hydrocarbyl or hydroxyhydrocarbyl groups R⁵ and R⁶ may contain from 1 to 50 carbon atoms. Preferably, R⁵ and R⁶ are lower hydrocarbyl groups. In one embodiment, R⁵ and R⁶ are alkylene groups containing from 4 to 7 carbon atoms, and in this embodiment, R⁵ and R⁶ together with the nitrogen atom bonded to R⁵ and R⁶ will form a heterocyclic group. The heterocyclic group (and the alkylene group) may contain other atoms such as oxygen and sulfur. Specific examples of the amines (R⁵R⁶NH) used to form the dithiocarbamates include, for example, methylamine, propylamine, dimethylamine, diethylamine, dipropylamine, dibutylamine, methylethylamine, methylcyclohexylamine, piperidine, morpholine, dihexylamine, dioctylamine, dicocoamine, methylhydroxyethylamine, di-hydroxyethylamine, piperazine, etc. The metal salts of dithiocarbamates are known in the art and can be prepared readily by one skilled in the art. One method of preparing alkali metal salts of dithiocarbamic acids involves the reaction of an amine, carbon disulfide and an alkali metal hydroxide. Generally, these reactants are mixed and reacted at low temperature such as between about zero and 15°C. In one embodiment, an aqueous amine is cooled to zero to 15°C and carbon disulfide is added dropwise, generally in an inert atmosphere before or during the addition of the alkali metal hydroxide. In another embodiment, the aqueous amine is cooled whereupon the alkali metal hydroxide is added followed by the carbon disulfide. When all of the reactants have been mixed at the low temperature of zero to 15°C, the mixture is allowed to warm to ambient temperature with stirring. The salts of dithiocarbamic acids prepared by the above procedure generally are reacted immediately with the sulfur intermediates which have been described above. Solvents may be included to facilitate the reaction, and alcohols have been found to be satisfactory solvents. The reaction between the sulfur intermediate and the dithiocarbamate salts generally is conducted at from ambient temperature to the reflux temperature of the mixture. The reaction is conducted until the reaction is completed which is generally from 5 to 24 hours. At the end of the reaction, the aqueous phase is separated, and the product is recovered from the organic phase. The product of the reaction of the sulfur monohalide with an olefinic hydrocarbon followed by reaction with the dithiocarbamate generally is a mixture of products which can be represented by the structural Formulae XVII or XVII-A. When the reaction is conducted with an aldehyde or a ketone in lieu of the olefinic hydrocarbon, the reaction product also is a mixture in which the major product is believed to be represented by the structural Formula XVII-B. It is not necessary to isolate the various products since the product mixtures are useful in lubricants and functional fluids. The sulfur-coupled dithiocarbamates (C-3) also may be prepared by a process which comprises the steps of (A) reacting an olefinic hydrocarbon with a halogen to produce a halogen-containing intermediate, and (B) reacting said intermediate with an alkali metal sulfide and a salt of a dithiocarbamate in an amount sufficient to replace the halogen groups present partially with dithiocarbamate groups and/or partially with sulfide groups. Any of the olefinic hydrocarbons and salts of dithiocarbamates described above may be utilized in this process. The reaction of a halogen with an olefinic hydrocarbon is well known in the art, and any procedure for effecting the reaction of a halogen with an olefinic hydrocarbon to produce a halogen-containing intermediate can be utilized. The alkali metal sulfide utilized in the second step may be generally represented by the structural formula M₂S x wherein M is an alkali metal and x is 1, 2 or 3. Sodium sulfide is preferred as the alkali metal sulfide for reasons of economy and effectiveness. In one embodiment, the halogen-containing intermediate is reacted first with the alkali metal sulfide and then with the salt of a dithiocarbamate. Although the above reactants can be reacted at various ratios, it is generally desired to react four equivalents of the halogen-containing intermediate with one mole of the alkali metal sulfide and two moles of the dithiocarbamate salt. The reactions may be conducted at any convenient temperature such as from ambient temperature up to about 100°C or higher in some instances. The product obtained by this reaction generally will be a mixture which comprises primarily sulfur-coupled dithiocarbamates which are useful in lubricants and functional fluids. Sulfur-Containing Compounds (C-4) : The sulfur compounds (C-4) which are useful in the compositions of the present invention are compounds characterized by the structural formula wherein in Formula I, R¹, R², R³ and R⁴ are each independently H or hydrocarbyl groups; R¹ and/or R³ may be G¹ or G²; R¹ and R² and/or R³ and R⁴ together may be alkylene groups containing about 4 to about 7 carbon atoms; G¹ and G² are each independently C(X)R, COOR, C≡N, R⁵-C=NR⁶, CON(R)₂, or NO₂, and G¹ may be CH₂OH, wherein X is O or S, each of R and R⁵ are independently H or a hydrocarbyl group, R⁶ is H or a hydrocarbyl group; when both G¹ and G² are R⁵C=NR⁶, the two R⁶ groups together may be hydrocarbylene group linking the two nitrogen atoms; when G¹ is CH₂OH and G² is COOR, a lactone may be formed by intramolecular combination of G¹ and G²; and x is a number from 1 to 8. R¹, R², R³ and R⁴ in Formula I are each independently hydrogen or hydrocarbyl group. The hydrocarbyl groups may be aliphatic or aromatic groups such as alkyl, cycloalkyl, alkaryl, aralkyl or aryl groups. R¹ and R² and/or R³ and R⁴ together may be alkylene groups containing from about 4 to about 7 carbon atoms. In these embodiments, R¹ and R² together with the carbon atom bonded to R¹ and R² in Formula I will form a cycloalkyl group. Similarly, R³ and R⁴ together with the carbon atom bonded to R³ and R⁴ will form a cycloalkyl group. Also, R¹ and/or R³ may be G¹ or G². The hydrocarbyl groups R¹, R², R³ and R⁴ usually will contain up to 30 carbon atoms. Preferably, the hydrocarbyl groups are alkyl groups containing up to 10 carbon atoms. Specific examples of hydrocarbyl groups include methyl, ethyl, isopropyl, isobutyl, secondary butyl, cyclohexyl, cyclopentyl, octyl, dodecyl, octadecyl, eicosyl, behenyl, triacontonyl, phenyl, naphthyl, phenethyl, octyl-phenyl, tolyl, xylyl, dioctadecyl-phenyl, triethyl-phenyl, chloro-phenyl, methoxy-phenyl, dibromo-phenyl, nitrophenyl, 3-chlorohexyl, etc. The sulfur compound (C-4) represented by Formula I may be thia-aldehydes or thia-ketones. That is, G¹ and G² in Formula I are C(O)R groups. Various thia-bisaldehyde compounds are known, and the synthesis of such compounds have been described in the prior art such as in U.S. Patents 3,296,137 and 2,580,695. Thia-aldehydes and thia-ketones are most conveniently prepared by the sulfurization of a suitable aldehyde or ketone such as one having the structural formula R¹R²CHC(O)R wherein R¹ is hydrogen, hydrocarbyl groups or C(O)R, R² is hydrogen or a hydrocarbyl group, and R is hydrogen or a hydrocarbyl group. In these instances, R³ and R⁴ in Formula I will be the same as R¹ and R², respectively, and both G¹ and G² are C(O)R groups. When R¹ is C(O)R, the sulfurization product contains four C(O)R groups. The sulfurization can be accomplished by reacting the aldehyde or ketone with a sulfur halide such as sulfur monochloride (i.e., S₂Cl₂), sulfur dichloride, sulfur monobromide, sulfur dibromide, and mixtures of sulfur halide with sulfur flowers in varying amounts. The reaction of an aldehyde or ketone with a sulfur halide may be effected simply by mixing the two reactants at the desired temperature which may range from -30°C to 250°C or higher. The preferred reaction temperature generally is within the range of from 10 to 80°C. The reaction may be carried out in the presence of a diluent or solvent such as benzene, naphtha, hexane, carbon tetrachloride, chloroform, mineral oil, etc. The diluent/solvent facilitates the control of the reaction temperature and a thorough mixing of the the reactants. The relative amounts of the aldehyde or ketone and the sulfur halide may vary over wide ranges. In most instances, the reaction involves two moles of the aldehyde or ketone and one mole of the sulfur halide. In other instances, an excess of either one of the reactants may be used. When sulfur compounds are desired which contain more than two sulfur atoms, (e.g., x is an integer from 3-8) these compounds can be obtained by reacting the aldehydes with a mixture of sulfur halide and sulfur. Sulfurization products wherein G¹ and G² are different and may be obtained by sulfurizing mixtures of aldehydes and ketones or mixtures of ketones containing different C(O)R groups. Specific examples of thia-aldehydes and thia-ketones include compounds as represented by Formula I wherein G¹ and G² are C(O)R groups, x is 1 to 4 and R¹, R², R³, R⁴ and R are as follows: R¹ R² R³ R⁴ R CH₃ H CH₃ H H CH₃ CH₃ CH₃ CH₃ CH₃ C₂₅ H C₂H₅ H H CH₃C(O)- H CH₃C(O)- H CH₃ CH₃C(O)- H CH₃C(O)- H H C₂H₅ C₄H₁₁ C₂H₅ C₄H₁₁ H The thia-aldehydes and thia-ketones which can be prepared as described above can be converted to derivatives containing other functional groups which are normally derivable therefrom. Thus, in some of the embodiments of the invention, a thia-aldehyde or thia-ketone is converted to a derivative through contemporneous conversion of the aldehyde or ketone groups to other terminal groups by chemical reactants and/or reagents. In such reactions, the thia group (S x ) and the R¹- R⁴ groups are inert and remain unchanged in the compound. For example, the thia-bisaldehydes can be converted to hydroxy-acid derivatives wherein one of the aldehyde groups (G¹) is converted to a COOH group, and the other aldehyde group (G²) is converted to a CH₂OH group. The hydroxy-acid derivatives are obtainable most conveniently by treating the corresponding thia-bisaldehyde with an alkaline reagent such as an alkali metal hydroxide or alkaline earth metal hydroxide, preferably a dilute aqueous solution thereof containing from 5 to 50% by weight of the hydroxide in water. Such alkaline reagents may be sodium hydroxide, potassium hydroxide, lithium hydroxide, barium hydroxide, calcium hydroxide, strontium hydroxide, etc. The hydroxy-acid is isolated from the reaction mixture by acidification with a mineral acid such as hydrochloric acid. The hydroxy-acid derivatives of thia-bisaldehydes can be represented by Formula I-A below. wherein R¹, R², R³, R⁴ and x are as previously defined. Specific examples of such hydroxy-acid derivatives include 6-hydroxy-2,2,5,5-tetramethyl-3,4-dithiahexanoic acid (i.e., conforming to Formula I-A wherein R¹, R², R³ and R⁴ are methyl and x is 2); 6-hydroxy-2,2-diethyl-5-propyl-5-butyl-3,4-dithiahexanoic acid; 6-hydroxy-2,2,5,5-tetraethyl-3,4-dithiahexanoic acid; etc. By virtue of the presence of the hydroxy group and the carboxylic group in the hydroxy-acids described by Formula I-A above, various other sulfur-containing compounds useful in the present invention can be obtained by the conversion of such hydroxy group and/or the carboxylic group to other polar groups normally derivable thereform. Examples of such derivatives include esters formed by esterification of either or both of the hydroxy group and the carboxylic group; amides, imides, and acyl halides formed through the carboxylic group; and lactones formed through intramolecular cyclization of the hydroxy-acid accompanied with the elimination of water. The procedures for preparing such derivatives are well known to those skilled in the art, and it is not believed necessary to unduly lengthen the specification by including a detailed description of such procedures. More specifically, the carboxylic group (COOH) in Formula I-A can be converted to ester groups (COOR) and amide groups (CON(R)₂) wherein the R groups may be hydrogen or hydrocarbyl groups containing from 1 to 30 carbon atoms and more generally from 1 to about 10 carbon atoms. Specific examples of such R groups include ethyl, propyl, butyl, phenyl, etc. The procedures for preparing lactones through intramolecular cyclization of hydroxy-acids of Formula I-A accompanied by the elimination of water are well known in the art. Generally, the cyclization is promoted by the presence of materials such as acetic anhydride, and the reaction is effected by heating the mixtures to elevated temperatures such as the reflux temperature while removing volatile materials including water. The sulfur compounds characterized by structural Formula I wherein G¹ and/or G² are R⁵C=NR⁶ can be prepared from the corresponding thia-aldehydes and thia-ketones. These mono- and di-imine compounds are prepared by reacting one mole of the dialdehyde (C(O)H) or diketone (C(O)R⁵) with one and two moles of an amine, respectively. The amines may be monoamines or polyamines. When polyamines are reacted with the thia-aldehydes or thia-ketones [-C(O)R⁵], cyclic di-imines can be formed. For example, when both G¹ and G² in Formula I are R⁵C=NR⁶, the two R⁶ groups together may be a hydrocarbylene group linking the two nitrogen atoms. The amines which are reacted with the thia-aldehydes and thia-ketones to form the imines may be characterized by the formula R⁶NH₂ wherein R⁶ is hydrogen, or hydrocarbyl, or an amino hydrocarbyl group. Generally, the hydrocarbyl groups will contain up to 30 carbon atoms and will more often by aliphatic hydrocarbyl groups containing from 1 to 30 carbon atoms. In one embodiment, the hydrocarbyl amines which are useful in preparing the imine derivatives of the present invention are primary hydrocarbyl amines containing from 2 to 30 carbon atoms in the hydrocarbyl group, and more preferably from 4 to 20 carbon atoms in the hydrocarbyl group. The hydrocarbyl group may be saturated or unsaturated. Representative examples of primary saturated amines are the lower alkyl amines such as methyl amine, ethyl amine, n-propyl amine, n-butyl amine, n-amyl amine, n-hexyl amine; those known as aliphatic primary fatty amines and commercially known as "Armeen" primary amines (products available from Armak Chemicals, Chicago, Illinois). Typical fatty amines include alkyl amines such as n-hexylamine, n-octylamine, n-decylamine, n-dodecylamine, n-tetradecylamine, n-pentadecylamine, n-hexadecylamine, n-octadecylamine (stearyl amine), etc. These Armeen primary amines are available in both distilled and technical grades. While the distilled grade will provide a purer reaction product, the desirable amides, imines and imides will form in reactions with the amines of technical grade. Also suitable are mixed fatty amines such as Armak's Armeen-C, Armeen- O, Armeen-OL, Armeen-T, Armeen-HT, Armeen S and Armeen SD. In another embodiment, the amine derived products of this invention are those derived from tertiaryaliphatic primary amines having at least 4 carbon atoms in the alkyl group. For the most part, they are derived from alkyl amines having a total of less than 30 carbon atoms in the alkyl group. Usually the tertiary aliphatic primary amines are monoamines represented by the formula wherein R is a hydrocarbyl group containing from one to 30 carbon atoms. Such amines are illustrated by tertiary-butyl amine, tertiary-hexyl primary amine, 1-methyl-1-amino-cyclohexane, tertiary-octyl primary amine, tertiary-decyl primary amine, tertiary-dodecyl primary amine, tertiary-tetradecyl primary amine, tertiary-hexadecyl primary amine, tertiary-octadecyl primary amine, tertiary-tetracosanyl primary amine, tertiary-octacosanyl primary amine. Mixtures of amines are also useful for the purposes of this invention. Illustrative of amine mixtures of this type are "Primene 81R" which is a mixture of C₁₁-C₁₄ tertiary alkyl primary amines and "Primene JM-T" which is a similar mixture of C₁₈-C₂₂ tertiary alkyl primary amines (both are available from Rohm and Haas Company). The tertiary alkyl primary amines and methods for their preparation are well known to those of ordinary skill in the art and, therefore, further discussion is unnecessary. The tertiary alkyl primary amine useful for the purposes of this invention and methods for their preparation are described in U.S. Patent 2,945,749. Primary amines in which the hydrocarbon chain comprises olefinic unsaturation also are useful. Thus, The R⁶ group may contain one or more olefinic unsaturation depending on the length of the chain, usually no more than one double bond per 10 carbon atoms. Representative amines are dodecenylamine, myristoleylamine, palmitoleylamine, oleylamine and linoleylamine. Such unsaturated amines also are available under the Armeen tradename. The thia-aldehydes and thia-ketones also can be reacted with polyamines. Examples of useful polyamines include diamines such as mono- or dialkyl, symmetrical or asymmetrical ethylene diamines, propane diamines (1,2, or 1,3), and polyamine analogs of the above. Suitable commercial fatty polyamines are "Duomeen C" (N-coco-1,3-diaminopropane), "Duomeen S" (N-soya-1,3-diaminopropane), "Duomeen T" (N-tallow-1,3-diaminopropane), or "Duomeen O" (N-oleyl-1,3-diaminopropane). "Duomeens" are commercially available diamines described in Product Data Bulletin No. 7-10R1 of Armak Chemical Co., Chicago, Illinois. The reaction of thia-aldehydes (and ketones) with primary amines or polyamines can be carried out by techniques well known to those skilled in the art. Generally, the thia-bisaldehyde or ketone is reacted with the amine or polyamine the reaction in a hydrocarbon solvent at an elevated temperature, generally in an atmosphere of nitrogen. As the reaction proceeds, the water which is formed is removed such as by distillation. Sulfur compounds characterized by structural Formula I wherein G¹ and G² may be COOR, C≡N and NO₂ can be prepared by the reaction of compounds characterized by the structural formula wherein R¹ and R² are as defined above, and G is COOR, C≡N or NO₂, or mixtures of different compound represented by Formula I-B with a sulfur halide or a mixture of sulfur halides and sulfur. Generally, about one mole of sulfur halide is reacted with about two moles of the compounds represented by Formula I-B. In one embodiment, R¹ also may be G. In such instances, the sulfur compounds which are formed as a result of the reaction with the sulfur halide will contain four G groups which may be the same or different depending upon the starting material. For example, when a di-ketone such as 2,4-pentanedione is reacted with sulfur mono-chloride, the resulting product contains four ketone groups; when the starting material contains a ketone group and an ester group (e.g., ethylacetoacetate), resulting product contains two ketone groups and two ester groups; and when the starting material contains two ester groups (e.g., diethylmalonate), the product contains four ester groups. Other combinations of functional groups can be introduced into the sulfur products utilized in the present invention and represented by Formula I by selecting various starting materials containing the desired functional groups. Sulfur compounds represented by Formula I wherein G¹ and/or G² and C≡N groups can be prepared by the reaction of compound represented by Formula I-B wherein G is C≡N and R¹ and R² are hydrogen or hydrocarbyl groups. Preferably, R¹ is hydrogen and R² is a hydrocarbyl group. Examples of useful starting materials include, for example, propionitrile, butyronitrile, etc. Compounds of Formula I wherein G¹ and G² are NO₂ groups can be prepared by (1) reacting a nitro hydrocarbon R¹R²C(H)NO₂ with an alkali metal or alkaline earth metal alkoxide to form the salt of the nitro hydrocarbon, and (2) reacting said salt with sulfur monochloride in an inert, anhydrous nonhydroxylic medium to form a bis (1-nitrohydrocarbyl) disulfide. Preferably the nitro hydrocarbon is a primary nitro hydrocarbon (R¹ is hydrogen and R² is hydrocarbyl). The starting primary nitro compounds used in carrying out this synthesis are well known. Illustrative compounds are nitroethane, 1-nitropropane, 1-nitrobutane, 1-nitro-4-methylhexane, (2-nitroethyl) benzene, etc. The nature of the alkanol used in obtaining the alkali or alkaline earth metal salt of the starting primary nitro compound is not critical. It is only necessary that it be appropriate for reaction with the metal to form the alkoxide. Because they are easily obtainable and inexpensive, the lower alkanols (i.e., alkanols of 1 to 4 carbon atoms) such as methanol, ethanol and butanol will usually be employed in the synthesis. The medium in which the salt is reacted with S₂Cl₂ must be inert to both the reactants. It is also essential that the medium be anhydrous and nonhydroxylic for the successful formation of the novel bis(1-nitrohydrocarbyl) disulfides. Examples of suitable media are ether, hexane, benzene, dioxane, higher alkyl ethers, etc. Ordinarily, it is preferable to maintain a temperature of about 0-10°C during the preparation of the metal salt. However, temperatures from 0 to 25°C may be used in this step of the process. In the preparation of the bisdisulfide temperatures in the range of -5 to +15°C may be used. Preferably, temperatures between 0 to 5°C are used in this step of the process. The preparation of various thia-bisnitro compounds useful in the present invention is described in some detail in U.S. Patent 3,479,413, and the disclosure of this patent is hereby incorporated by reference. Representative examples of nitro sulfides useful in the present invention are: bis(1-nitro-2-phenylethyl) disulfide, bis(1-nitrodecyl) disulfide, bis(1-nitrododecyl) disulfide, bis(1-nitro-2-phenyldecyl) disulfide, bis(1-nitro-2-cyclohexylethyl) disulfide, bis(1-nitropentadecyl) disulfide, bis(1-nitro-3-cyclobutylpropyl) disulfide bis(1-nitro-2-naphthylethyl) disulfide, bis(1-nitro-3-p-tolylpropyl) disulfide, bis(1-nitro-2-cyclooctylethyl) disulfide, and the like. The carboxylic ester-containing sulfur compounds (i.e., G¹ is COOR) described above can be utilized to prepare other sulfur compounds useful in the present invention. For example, the ester (COOR) can be hydrolyzed to the carboxylic acid (COOH) which can be converted to other esters by reaction with various alcohols or to amides by reaction with various amines including ammonia in primary or secondary amines such as those represented by the formula (R)₂NH wherein each R is hydrogen or a hydrocarbyl group. These hydrocarbyl groups may contain from 1 to 30 carbon atoms and more generally will contain from 1 to 10 carbon atoms. As mentioned above, R¹ and R² and/or R³ and R⁴ together may be alkylene groups containing from 4 to 7 carbon atoms. In this embodiment, R¹ and R² (and R³ and R⁴) form a cyclic compound with the common carbon atom (i.e., the carbon atom which is common to R¹ and R² in Formula I. Such derivatives of structural Formula I can be prepared by reacting the appropriately substituted saturated cyclic material with sulfur halides as described above. Examples of such cyclic starting materials include cyclohexane carboxaldehyde (C₆H₁₁CHO), cyclohexane carbonitrile (C₆H₁₁CN), cyclohexane carboxamide (C₆H₁₁CONH₂), cyclohexane carboxylic acid (C₆H₁₁COOH), cyclobutane carboxylic acid (C₄H₇COOH), cycloheptane carboxylic acid (C₇H₁₃COOH), cycloheptyl cyanide (C₇H₁₃CN), etc. The following Example 1 illustrates the preparation of a sulfur composition represented by Formula I. Unless otherwise indicated in this example as well as throughout the specification and the appended claims, all parts and percentages are by weight, and all temperatures are in degrees centigrade. Example 1 Sulfur monochloride (1620 parts, 12 moles) is charged to a 5-liter flask and warmed under nitrogen to a temperature of about 53°C whereupon 1766 parts (24.5 moles) of isobutyraldehyde are added dropwise under nitrogen at a temperature of 53-60°C over a period of about 6.5 hours. After the addition of the isobutyraldehyde is completed, the mixture is heated slowly over a period of 6 hours to a temperature of about 100°C while blowing with nitrogen. The mixture is maintained at 100°C with nitrogen blowing for a period of about 6 hours and volatile materials are removed from the reaction vessel. The reaction product then is filtered through a filter aid, and the filtrate is the desired product containing 31.4% sulfur (theory, 31.08%). The desired reaction product, predominantly 2,2′-dithiodiisobutyraldehyde, is recovered in about 95% yield. Components (A), (B) and (C) of the inventive compositions can be mixed in any order using techniques known to those of ordinary skill in the art. Preferably, the relative weight ratios of components (A):(B):(C) in the compositions of the invention are generally about (1-500):(0.1-10): (1-500). Lubricants and Functional Fluids : The compositions of this invention are useful as additives for lubricants and functional fluids. These compositions can be employed in a wide variety of lubricants and functional fluids based on a wide variety of oils of lubricating viscosity, including natural and synthetic lubricating oils and mixtures thereof. These lubricants and functional fluids include crankcase lubricating oils for spark-ignited and compression-ignited internal combustion engines, including automobile and truck engines, two-cycle engines, aviation piston engines, marine and railroad diesel engines, and the like. They can also be used in gas engines, stationary power engines and turbines and the like. Transmission fluids (including both automatic transmission fluids and manual transmission fluids), transaxle lubricants, gear lubricants, metal-working lubricants, hydraulic fluids and other lubricating oil and grease compositions can also benefit from the incorporation therein of the compositions of the present invention. Natural oils include animal oils and vegetable oils (e.g., castor oil, lard oil) as well as solvent-refined or acid-refined mineral lubricating oils of the paraffinic, naphthenic, or mixed paraffin-naphthenic types. Oils of lubricating viscosity derived from coal or shale are also useful base oils. Synthetic lubricating oils include hydrocarbon oils and halo-substituted hydrocarbon oils such as polymerized and interpolymerized olefins (e.g., polybutylenes, polypropylenes, propylene-isobutylene copolymers, chlorinated polybutylenes, etc. ); alkyl benzenes (e.g., dodecylbenzenes, tetradecylbenzenes, dinonylbenzenes, di-(2-ethylhexyl) benzenes, etc.); polyphenyls (e.g., biphenyls, terphenyls, alkylated polyphenyls, etc.); and the like. Alkylene oxide polymers and interpolymers and derivatives thereof where the terminal hydroxyl groups have been modified by esterification, etherification, etc., constitute another class of known synthetic lubricating oils that can be used. These are exemplified by the oils prepared through polymerization of ethylene oxide or propylene oxide, the alkyl and aryl ethers of these polyoxyalkylene polymers (e.g., methyl-polyisopropylene glycol ether having an average molecular weight of about 1000, diphenyl ether of polyethylene glycol having an average molecular weight of 500-1000, diethyl ether of polypropylene glycol having an average molecular weight of 1000-1500, etc.) or mono- and polycarboxylic esters thereof, for example, the acetic acid esters, mixed C₃-C₈ fatty acid esters, or the C₁₃ oxo acid diester of tetraethylene glycol. Another suitable class of synthetic lubricating oils that can be used comprises the esters of dicarboxylic acids (e.g., phthalic acid, succinic acid, alkyl succinic acid, maleic acid, azelaic acid, suberic acid, sebacic acid, fumaric acid, adipic acid, linoleic acid dimer, malonic acid, alkyl malonic acids, alkenyl malonic acids, etc.) with a variety of alcohols (e.g., butyl alcohol, hexyl alcohol, dodecyl alcohol, 2-ethylhexyl alcohol, ethylene glycol, diethylene glycol monoether, propylene glycol, pentaerythritol, etc.). Specific examples of these esters include dibutyl adipate, di(2-ethylhexyl)-sebacate, di-n-hexyl fumerate, dioctyl sebacate, diisooctyl azelate, diisodecyl azelate, dioctyl phthalate, didecyl phthalate, dieicosyl sebacate, the 2-ethylhexyl diester of linoleic acid dimer, the complex ester formed by reacting one mole of sebacic acid with two moles of tetraethylene glycol and two moles of 2-ethyl-hexanoic acid, and the like. Esters useful as synthetic oils also include those made from C₅ to C₁₂ monocarboxylic acids and polyols and polyol ethers such as neopentyl glycol, trimethylol propane, pentaerythritol, dipentaerythritol, tripentaerythritol, etc. Silicon-based oils such as the polyalkyl-, polyaryl-, polyalkoxy-, or polyaryloxy-siloxane oils and silicate oils comprise another class of useful oils. These include tetraethyl-silicate, tetraisopropyl-silicate, tetra-(2-ethylhexyl)-silicate, tetra-(4-methylhexyl)-silicate, tetra(p-tert-butylphenyl)-silicate, hexyl-(4-methyl-2-pentoxy)-di-siloxane, poly(methyl)-siloxanes, poly-(methylphenyl)-siloxanes, etc. Other useful synthetic oils include liquid esters of phosphorus-containing acid (e.g., tricresyl phosphate, trioctyl phosphate, diethyl ester of decane phosphonic acid, etc.), polymeric tetrahydrofurans, and the like. Unrefined, refined and rerefined oils (and mixtures of each with each other) of the type disclosed hereinabove can be used in the lubricant and functional fluid compositions of the present invention. Unrefined oils are those obtained directly from a natural or synthetic source without further purification treatment. For example, a shale oil obtained directly from a retorting operation, a petroleum oil obtained directly from distillation or ester oil obtained directly from an esterification process and used without further treatment would be an unrefined oil. Refined oils are similar to the unrefined oils except that they have been further treated in one or more purification steps to improve one or more properties. Many such purification techniques are known to those of skill in the art such as solvent extraction, distillation, acid or base extraction, filtration, percolation, etc. Rerefined oils are obtained by processes similar to those used to obtain refined oils applied to refined oils which have been already used in service. Such rerefined oils are also known as reclaimed or reprocessed oils and often are additionally processed by techniques directed toward removal of spent additives and oil breakdown products. Generally, the lubricants and functional fluids of the present invention contain an effective amount of the composition of this invention sufficient to provide said lubricants and functional fluids with improved anti-wear, load-carrying, extreme pressure (E.P.), and/or corrosion-inhibiting properties. Normally the compositions of the present invention will be employed in such lubricants and functional fluids at a level in the range of 0.02% to 20% by weight, preferably 0.05% to 5% by weight of the total weight of the lubricant or functional fluid. Preferably, component (A) is employed at a concentration in the range of 0.01% to 5%, more preferably 0.01% to 2%, more preferably 0.01% to 1% by weight based on the total weight of the lubricant or functional fluid. Component (B) is preferably employed at a concentration in the range of 0.001% to 0.1% by weight based on the total weight of the lubricant or functional fluid. Component (C) is preferably employed at a concentration in the range of 0.01% to 5% by weight based on the total weight of the lubricant or functional fluid. The invention also contemplates the use of lubricants and functional fluids containing other additives in addition to the compositions of this invention. Such additives include, for example, ashless detergents and dispersants, corrosion-inhibiting agents, antioxidants, viscosity improving agents, E.P. agents, pour point depressants, color stabilizers, anti-foam agents, etc. Ashless detergents and dispersants are so called despite the fact that, depending on its constitution, the dispersant may upon combustion yield a non-volatile material such as boric oxide or phosphorus pentoxide; however, it does not ordinarily contain metal and therefore does not yield a metal-containing ash on combustion. Many types are known in the art, and any of them are suitable for use in the lubricants of this invention. The following are illustrative: (1) Reaction products of carboxylic acids (or derivatives thereof) containing at least 34 and preferably at least 54 carbon atoms with nitrogen containing compounds such as amine, organic hydroxy compounds such as phenols and alcohols, and/or basic inorganic materials. Examples of these "carboxylic dispersants" are described in British Patent 1,306,529 and in many U.S. Patents including the following: 3,163,603 3,351,552 3,541,012 3,184,474 3,381,022 3,543,678 3,215,707 3,399,141 3,542,680 3,129,666 3,415,750 3,567,637 3,271,310 3,433,744 3,574,101 3,272,746 3,444,170 3,576,743 3,281,357 3,448,048 3,630,904 3,306,908 3,448,049 3,632,510 3,311,558 3,451,933 3,632,511 3,316,177 3,454,607 3,697,428 3,340,281 3,467,668 3,725,441 3,341,542 3,501,405 4,234,435 3,346,493 3,522,179 Re 26,433 (2) Reaction products of relatively high molecular weight aliphatic or alicyclic halides with amines, preferably oxyalkylene polyamines.

Extreme pressure (E.P.) agents, corrosion-inhibiting agents and antioxidants which may be included in the lubricants and functional fluids of the invention are exemplified by chlorinated aliphatic hydrocarbons such as chlorinated wax; organic sulfides and polysulfides such as benzyl disulfide, bis(chlorobenzyl)disulfide, dibutyl tetrasulfide, sulfurized methyl ester of oleic acid, sulfurized alkylphenol, sulfurized dipentene, and sulfurized terpene; phosphosulfurized hydrocarbons such as the reaction product of a phosphorus sulfide with turpentine or methyl oleate, phosphorus esters including principally dihydrocarbon and trihydrocarbon phosphites such as dibutyl phosphite, diheptyl phosphite, dicyclohexyl phosphite, pentylphenyl phosphite, dipentylphenyl phosphite, tridecyl phosphite, distearyl phosphite, dimethyl naphthyl phosphite, oleyl 4-pentylphenyl phosphite, polypropylene (molecular weight 500)-substituted phenyl phosphite, diisobutyl-substituted phenyl phosphite; metal thiocarbamates, such as zinc dioctyldithiocarbamate, and barium heptylphenyl dithiocarbamate; Group II metal phosphorodithioates such as zinc dicyclohexylphosphorodithioate, zinc dioctylphosphorodithioate, barium di(heptylphenyl)-phoshorodithioate, cadmium dinonylphosphorodithioate, and the zinc salt of a phosphorodithioic acid produced by the reaction of phosphorus pentasulfide with an equimolar mixture of isopropyl alcohol and n-hexyl alcohol. Many of the above-mentioned extreme pressure agents, corrosion inhibitors and antioxidants also serve as antiwear agents. Zinc dialkylphosphorodithioates are a well known example. Pour point depressants are a particularly useful type of additive often included in the lubricants and functional fluids described herein. The use of such pour point depressants in oil-based compositions to improve low temperature properties of oil-based compositions is well known in the art. See, for example, page 8 of "Lubricant Additives" by C.V. Smalheer and R. Kennedy Smith (Lezius-Hiles Co. publishers, Cleveland, Ohio, 1967). Examples of useful pour point depressants are polymethacrylates; polyacrylates; polyacrylamides; condensation products of haloparaffin waxes and aromatic compounds; vinyl carboxylate polymers; and terpolymers of dialkylfumarates, vinyl esters of fatty acids and alkyl vinyl ethers. Pour point depressants useful for the purposes of this invention, techniques for their preparation and their uses are described in U.S. Patents 2,387,501; 2,015,748; 2,655,479; 1,815,022; 2,191,498; 2,666,746; 2,721,877; 2,721,878; and 3,250,715. Anti-foam agents are used to reduce or prevent the formation of stable foam. Typical anti-foam agents include silicones or organic polymers. Additional anti-foam compositions are described in "Foam Control Agents", by Henry T. Kerner (Noyes Data Corporation, 1976), pages 125-162. Components (A), (B) and (C) of the compositions of this invention can be added directly to the lubricant or functional fluid. Preferably, however, they are diluted with a substantially inert, normally liquid organic diluent such as mineral oil, naphtha, benzene, toluene or xylene, to form an additive concentrate. These concentrates usually contain from 10% to 90% by weight of the inventive compositions and may contain, in addition, one or more other additives known in the art or described hereinabove. The remainder of the concentrate is the substantially inert normally liquid diluent. Examples of hydraulic fluids within the scope of the invention are as follows (all numerical values being parts by weight): The lubricant compositions of the present invention may be in the form of greases in which any of the above-described oils of lubricating viscosity can be employed as a vehicle. Where the lubricant is to be used in the form of a grease, the lubricating oil generally is employed in an amount sufficient to balance the total grease composition and generally, the grease compositions will contain various quantities of thickening agents and other additive components to provide desirable properties. A wide variety of thickening agents can be used in the preparation of the greases of this invention. Included among the thickening agents are alkali and alkaline earth metal soaps of fatty acids and fatty materials having from 12 to 30 carbon atoms. The metals are typified by sodium, lithium, calcium and barium. Examples of fatty materials include stearic acid, hydroxy stearic acid, stearin, oleic acid, palmetic acid, myristic acid, cottonseed oil acids, and hydrogenated fish oils. Other thickening agents include salt and salt-soap complexes as calcium stearate-acetate (U.S. Patent 2,197,263), barium stearate acetate (U.S. Patent 2,564,561), calcium stearate-caprylate-acetate complexes (U.S. Patent 2,999,065), calcium caprylate-acetate (U.S. Patent 2,999,066), and calcium salts and soaps of low-, intermediate- and high-molecular weight acids and of nut oil acids. Particularly useful thickening agents employed in the grease compositions are essentially hydrophilic in character, but which have been converted into a hydrophobic condition by the introduction of long chain hydrocarbon radicals onto the surface of the clay particles prior to their use as a component of a grease composition, as, for example, by being subjected to a preliminary treatment with an organic cationic surface-active agent, such as an onium compound. Typical onium compounds are tetraalkylammonium chlorides, such as dimethyl dioctadecyl ammonium chloride, dimethyl dibenzyl ammonium chloride and mixtures thereof. This method of conversion, being well known to those skilled in the art, and is believed to require no further discussion. More specifically, the clays which are useful as starting materials in forming the thickening agents to be employed in the grease compositions, can comprise the naturally occurring chemically unmodified clays. These clays are crystalline complex silicates, the exact composition of which is not subject to precise description, since they vary widely from one natural source to another. These clays can be described as complex inorganic silicates such as aluminum silicates, magnesium silicates, barium silicates, and the like, containing, in addition to the silicate lattice, varying amounts of cation-exchangeable groups such as sodium. Hydrophilic clays which are particularly useful for conversion to desired thickening agents include montmorillonite clays, such as bentonite, attapulgite, hectorite, illite, saponite, sepiolite, biotite, vermiculite, zeolite clays, and the like. The thickening agent is employed in an amount from 0.5 to 30, and preferably from 3% to 15% by weight of the total grease composition.
