Description: Title: ORGANOMETALLIC COMPLEX-ANΗOXTOANT COMBINA- ΗONS, AND CONCENTRATES AND DffiSELFUELS CONTAIN¬ ING SAME 5 Technical Field of the Invention This invention relates to combinations of (A) organometallic complexes and (B) antioxidants. These combinations can be used in diesel fuels for operating diesel engines equipped with exhaust system particulate traps. The combination of (A) and (B) is useful in lowering the ignition temperature of 10 exhaust particles collected in the trap. The organometallic complex (A) is soluble or stably dispersible in the diesel fuel and is derived from (i) an organic compound containing at least two functional groups attached to a hydrocarbon linkage, and (ii) a metal reactant capable of forming a complex with the organic compound (i). The metal can be any metal capable of reducing the ignition 15 temperature of the exhaust particles with Na, K, Mg, Ca, Sr, Ba, V, Cr, Fe, Co, Cu, Zn, Pb, Sb, or a mixture of two or more thereof being useful. Background of the Invention Diesel engines have been employed as engines for over-the-road P ' vehicles because of relatively low fuel costs and improved mileage. However, 20 because of their operating characteristics, diesel engines discharge a larger amount of carbon black particles or very fine condensate particles or agglomer¬ ates thereof as compared to the gasoline engine. These particles or condensates are sometimes referred to as "diesel soot", and the emission of such particles or soot results in pollution and is undesirable. Moreover, diesel soot has been observed to be rich in condensed, polynuclear hydrocarbons, and some of these have been recognized as carcinogenic. Accordingly, particulate traps or filters have been designed for use with diesel engines that are capable of collecting carbon black and condensate particles. Conventionally, the particulate traps or filters have been composed of a heat-resistant filter element which is formed of porous ceramic or metal fiber and an electric heater for heating and igniting carbon particulates collected by the filter element. The heater is required because the temperatures of the diesel exhaust gas under normal operating conditions are insufficient to burn off the accumulated soot collected in the filter or trap. Generally, temperatures of about 450-600°C are required, and the heater provides the necessary increase of the exhaust temperature in order to ignite the particles collected in the trap and to regenerate the trap. Otherwise, there is an accumulation of carbon black, and the trap is eventually plugged causing operational problems due to exhaust back pressure buildup. The above-described heated traps do not provide a complete solution to the problem because the temperature of the exhaust gases is lower than the ignition temperature of carbon particulates while the vehicle runs under normal conditions, and the heat generated by the electric heater is withdrawn by the flowing exhaust gases when the volume of flowing exhaust gases is large. Alternatively, higher temperatures in the trap can be achieved by periodically enriching the air/fuel mixture burned in the diesel engine thereby producing a higher exhaust gas temperature. However, such higher temperatures can cause run-away regeneration leading to high localized temperatures which can damage the trap. It also has been suggested that the particle build-up in the traps can be controlled by lowering the ignition temperature of the particulates so that the particles begin burning at the lowest possible temperatures. One method of lowering the ignition temperature involves the addition of a combustion improver to the exhaust particulate, and the most practical way to effect the addition of the combustion improver to the exhaust particulate is by adding the combustion improver to the fuel. Copper compounds have been suggested as combustion improvers for fuels including diesel fuels. The U.S. Environmental Protection Agency (EPA) estimates that 5 the average sulfur content of on-highway diesel fuel is approximately 0.25% by weight and has required this level be reduced to no more than 0.05% by weight by October 1, 1993. The EPA has also required that this diesel fuel have a minimum cetane index specification of 40 (or meet a maximum aromatics level of 35%). The objective of this rule is to reduce sulfate particulate and 10 carbonaceous and organic particulate emissions. See, Federal Register, Vol. 55, No. 162, August 21, 1990, pp. 34120-34151. Low-sulfur diesel fuels and technology for meeting these emission requirements have not yet been commercially implemented. One approach to meeting these requirements is to provide a low-sulfur diesel fuel additive that can be effectively used in a low- 15 sulfur diesel fuel environment to reduce the ignition temperatures of soot that is collected in the particulate traps of diesel engines. U.S. Patent 3,346,493 discloses lubricating compositions containing metal complexes made of the reaction products of hydrocarbon-substituted succinic acid (e.g., polyisobutylene-substitutedsuccinic anhydride) compounds and 20 alkylene amines (e.g., polyalkylene polyamines), the complexes being formed by reacting at least about 0.1 equivalent of a complex-forming metal compound with the reaction products. The metals are those having atomic numbers from 24 to 30 (i.e., Cr, Mn, Fe, Co, Ni, Cu and Zn).

The reference indicates that fuels containing this I combination are stable upon storage and effective in reducing soot formation in the exhaust gas of an internal combustion engine. A preferred metal compound is a transition metal complex of a Mannich base, the Mannich base being derived 30 from (A) an aromatic phenol, (B) an aldehyde or a ketone, and (C) a hydroxyl- and/or thiol-containing amine.

International Publication No. WO 88/02392 discloses a method for operating a diesel engine equipped with an exhaust system particulate trap to reduce the build-up of exhaust particles collected in the trap. The method comprises operating the diesel engine with a fuel containing an effective amount of a titanium or zirconium compound or complex to lower the ignition tempera¬ ture of the exhaust particulates collected in the trap.

Description of the Preferred Embodiments The term "hydrocarby and cognate terms such as "hydrocarbyl¬ ene", "hydrocarbylidene", "hydrocarbon-based", etc, denote a chemical 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 "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 aromatic groups which are referred to in this specification and in the appended claims relative to the structure of the organometallic complexes of this invention, and in some instances are represented by " Ar" in formulae that are provided herein, can be mononuclear, such as phenyl, pyridyl, 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 about 6 sulfur atoms, sulfuiyl 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 about 6 carbon atoms, amino linkages, polyamino linkages and mixtures of such divalent bridging linkages. i certain instances, more than one bridging linkage can be present 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, the aromatic group will contain only carbon atoms in the aromatic nuclei per se (plus any alkyl or alkoxy substituent present). The aromatic group can be a single ring aromatic group represented by the 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 or nitro group, and m is 0 to 4. Specific examples of when the aromatic group 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 the aromatic group is a polynuclear fused-ring aromatic group, it can be represented by the general formula ar- ar m'ΛQJmm' 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 the aromatic group is a fused ring aromatic group include: 62 Whenthe aromatic group is a linked polynuclear aromatic group it can be represented by the general formula ar- Lng-ar -H-XQ) - * mw wherein is a number of 1 to about 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., O II -CO. sulfide linkages (e.g., -S-), polysulfide linkages of 2 to 6 sulfur atoms (e.g., -S- 2 ^), sulfinyl linkages (e.g., -S(O)-), sulfonyl linkages (e.g., -S(O) 2 -), lower alkylene linkages (e.g., -CH 2 -, -CH 2 -CH 2 - J -CH 2 "CH-, R° etc.), di(lower alkyl)-methylene linkages (e.g., CR° 2 -), lower alkylene ether linkages (e.g., -CH 2 O-, -CH 2 O-CH 2 -, -CH 2 -CH 2 -O-, -CH 2 CH 2 OCH 2 CH 2 -, -CED j CHOCH j CH- R° R° -CH CHOCHCH2- 1 R° R° 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 ^ group), amino linkages (e.g., -N-, -N-, -CH- j N-, -CH j NCE^-, -alk-N-, H R° where alk is lower alkylene, etc.), polyamino linkages (e.g., -N(alk N)ι.ιo 0762 -10- 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 ^Tar^Cm'. Specific examples of when the aromatic group is a linked polynuclear aromatic group include: For such reasons as cost, availability, performance, etc., the aromatic group is normally a benzene nucleus, lower alkylene bridged benzene nucleus, or a naphthalene nucleus.

R 11 and R 12 are independently H or hydrocarbyl groups, of up to about 30 carbon atoms. The "alkylene" group preferably contains up to about 10 carbon atoms, with methylene, ethylene and propylene being preferred. These alkylene amines include methylene amines, ethylene amines, butylene amines, propylene amines, pentylene amines, hexylene amines, heptylene amines, octylene amines, other polymethylene amines, and also the cyclic and the higher homologues of such amines such as piperazines and amino-alkyl-substituted piperazines. 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(trimeΛylene)-triamine, 2-heptyl-3-(2-aιmnopropyl)irniα'azoline, 4-memyl-imidazoline, l,3-bis(2-aminoethyl)imidazoline, pyrimidine, l-(2-amino- propyl)piperazine. l,4-bis(2-aminoethyl)piperazine, and 2-methyl-l-(2-amino- butyl)piperazine.

Higher homologues such as are obtained by condensation of the above-illustrated alkylene amines or hydroxyalkyl-substituted alkylene amines through amino groups or through hydroxy groups are likewise useful as the reactant (A-3). It will be appreciated that condensation through amino groups results in a higher amine accompanied with removal of ammonia and that condensation through the hydroxy groups results in products containing ether linkages accompanied with removal of water. The preparation of the aromatic Mannichs can be carried out by a variety of methods known in the art. One method involves adding the (A-l) hydroxyl and/or tMoL-containing aromatic compound, the (A-2) aldehyde or ketone, and the (A-3) amine compound to a suitable vessel and heating to carry out the reaction. Reaction temperatures from about ambient to about the decomposition temperature of any component or the Mannich product can be utilized. During reaction, water is drawn off as by sparging. Desirably, the reaction is carried out in solvent such as an aromatic type oil. The amount of the various reactants utilized is desirably on a mole to mole basis of (A-l) and (A-2) for each (A-3) secondary amino group or on a two-mole basis of (A-l) and (A-2)for each (A-3) primary amino group, although larger or smaller amounts can also be utilized. In another method of preparing the aromatic Mannichs, the hydroxyl and/or thiol-containing aromatic compound (A-l) and the amine compound (A-3) are added to a reaction vessel. The aldehyde or ketone (A-2) is generally rapidly added and the exothermic reaction generated is supplemented by mild heat such that the reaction temperature is from about 60°C to about 90°C. Desirably the addition temperature is less than the boiling point of water, otherwise, the water will bubble off and cause processing problems. After the reaction is essentially complete, the water by-product is removed in any conventional manner as by evaporation thereof which can be achieved by applying a vacuum, applying a sparge, heating or the like. A nitrogen sparge is often utilized at a temperature of from about 100°C to about 120°C. Lower temperatures can be utilized.

(19) Borated Acylated Amines Component (i) can be a borated acylated amine. These compounds can be prepared by first reacting a hydrocarbyl-substituted succinic acid-produc¬ ing compound (herein sometimes referred to as the "succinic acylating agent") with at least about one-half equivalent, per equivalent of acid-producing compound, of an amine containing at least one hydrogen attached to a nitrogen group. The nitrogen-containing compositions obtained in this manner are usually complex mixtures. These nitrogen-containing compositions are sometimes referred to herein as "acylated amines". The nitiogen- * -containing composition is then borated by reacting it with a boron compound selected from the group consisting of boron trioxides, boron halides, boron acids, boron amides, and esters of boron acids. The acylated amines have been described in many U.S. patents including 3,172,892 3,341,542 3,630,904 3,215,707 3,346,493 3,632,511 3,272,746 3,444,170 3,787,374 3,316,177 3,454,607 4,234,435 3,541,012 The above U.S. patents are expressly incorporated herein by reference for their teaching of the preparation of acylated amines that are useful herein. i general, a convenient route for the preparation of the acylated . amines comprises the reaction of a hydrocarbyl-substituted succinic acid-pro- ducing compound ("carboxylic acid acylating agent") with an amine containing at least one hydrogen attached to a nitrogen atom (i.e., H-N=). The hydrocarbon- substituted succinic acid-producing compounds include the succinic acids, anhydrides, halides and esters. The number of carbon atoms in the hydrocarbon substituent on the succinic acid-producing compound may vary over a wide range provided that the organometallic complex produced therefrom is soluble or stably dispersible in diesel fuel. The hydrocarbon substituent generally will contain an average of at least about 10 aliphatic carbon atoms, preferably at least about 30 aliphatic carbon atoms, more preferably at least about 50 aliphatic carbon atoms. The sources of the substantially hydrocarbon substituent include principally the high molecular weight substantially saturated petroleum fractions and substantially saturated olefin polymers, particularly polymers of mono-ole- fins having from 2 to 30 carbon atoms. The especially useful polymers are the polymers of 1-mono-olefins such as ethylene, propene, 1-butene, isobutene, 1-hexene, 1-octene, 2-methyl-l-heptene, 3-cyclohexyl-l-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. They are illustrated by 2-butene, 3-pentene, and 4-octene. Also useful are the interpolymers of the olefins such as those illustrated above with other interpolymerizable olefinic substances such as aromatic olefins, cyclic olefins, and polyolefins. Such interpolymers include, for example, those prepared by polymerizing isobutene with styrene; isobutene with butadiene; propene with isoprene; 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-l-butene with 1-octene; 3,3-dimethyl-l-pentene with 1-hexene; isobutene with styrene and piperylene; etc. The relative proportions of the mono-olefins to the other monomers in the interpolymers influence the stability and oil-solubility of the final products derived from such interpolymers. Thus, for reasons of oil-solubility and stability the interpolymers contemplated for use in this invention should be substantially aliphatic and substantially saturated, i.e., they should contain at least about 80%, preferably at least about 95%, on a weight basis of units derived from the alipha¬ tic monoolefins and no more than about 5% of olefinic linkages based on the total number of carbon-to-carbon covalent linkages. In most instances, the percentage of olefinic linkages should be less than about 2% of the total number of carbon-to-carbon covalent linkages. Specific examples of such interpolymers include copolymer of 95% (by weight) of isobutene with 5% of styrene; terpolymer of 98% of isobutene with 1 % of piperylene and 1 % of chloroprene; terpolymer of 95 % of isobutene with 2 % of 1-butene and 3% of 1-hexene, terpolymer of 80% of isobutene with 20% of 1-pentene and 20% of 1-octene; copolymer of 80% of 1-hexene and 20% of 1-heptene; terpolymer of 90% of isobutene with 2% of cyclohexene and 8% of propene; and copolymer of 80% of ethylene and 20% of propene. Another source of the substantially hydrocarbon group comprises saturated aliphatic hydrocarbons such as highly refined high molecular weight white oils or synthetic alkanes such as are obtained by hydrogenation of high molecular weight olefin polymers illustrated above or high molecular weight olefinic substances. The use of olefin polymers having number average molecular weights (Mn) of about 700-10,000 is preferred. In one embodiment the substituent is derived from a polyolefin characterized by an Mn value of about 700 to about 10,000, and an Mw/Mn value of 1.0 to about 4.0. In preparing the substituted succinic acylating agents, one or more of the above-described polyalkenes is reacted with one or more acidic reactants selected from the group consisting of maleic or fumaric reactants such as acids or anhydrides. Ordinarily the maleic or fumaric reactants will be maleic acid, fumaric acid, maleic anhydride, or a mixture of two or more of these. The maleic reactants are usually preferred over the fumaric reactants because the former are more readily available and are, in general, more readily reacted with the polyalkenes (or derivatives thereof) to prepare the substituted succinic acid-producing compounds useful in the present invention. The especially preferred reactants are maleic acid, maleic anhydride, and mixtures of these. Due to availability and ease of reaction, maleic anhydride will usually be employed. For convenience and brevity, the term "maleic reactant" is often used hereinafter. When used, it should be understood that the term is generic to acidic reactants selected from maleic and fumaric reactants including a mixture of such reactants. Also, the term "succinic acylating agents" is used herein to represent the substituted succinic acid-producing compounds. One procedure for preparing the substituted succinic acylating agents of this invention is illustrated, in part, in U.S. Patent 3,219,666 which is expressly incorporated herein by reference for its teachings in regard to preparing succinic acylating agents. This procedure is conveniently designated as the "two-step procedure". This procedure involves first chlorinating the polyalkene, then reacting the chlorinated polyalkene with the maleic reactant. Another procedure for preparing these substituted succinic acid acylating agents utilizes a process described in U.S. Patent 3,912,764 and U.K. Patent 1,440,219, both of which are expressly incorporated herein by reference for their teachings in regard to that process. According to that process, the polyalkene and the maleic reactant are first reacted by heating them together in a "direct alkylation" procedure. When the direct alkylation step is completed, chlorine is introduced into the reaction mixture to promote reaction of the remaining unreacted maleic reactants. Another process for preparing the substituted succinic acylating agents of this invention is the so-called "one-step" process. This process is described in U.S. Patents 3,215,707 and 3,231,587. Both are expressly incorpo¬ rated herein by reference for their teachings in regard to that process. The one-step process involves preparing a mixture of the polyalkene and the maleic reactant containing the necessary amounts of both to provide the desired substituted succinic acylating agents of this invention. This means that there must be at least one mole of maleic reactant for each mole of polyalkene in order that there can be at least one succinic group for each equivalent weight of substituent groups. Chlorine is then introduced into the mixture, usually by passing chlorine gas through the mixture with agitation. The amines which are reacted with the succinic acid-producing compounds to form the acylated amines may be any of the amines (A-3) described above for us in preparing the aromatic Mannichs of this invention. A preferred class of such amines are the alkylene polyamines represented by Formula (A-3-3) above. The acylated amines obtained by reaction of the succinic acid-producing compounds and the amines described above may be amine salts, amides, imides, imidazolines as well as mixtures thereof. To prepare the acylated amines, one or more of the succinic acid-producing compounds and one or more of the amines are heated, optionally in the presence of a normally liquid, substantially inert organic liquid solvent diluent at an elevated temperature generally in the range of from about 80°C up to the decomposition point of the mixture or the product. Normally, temperatures in the range of about 100°C up to about 300°Care utilized provided that 300°C does not exceed the decomposi¬ tion point. The succinic acid-producing compound and the amine are reacted in amounts sufficient to provide at least about one-half equivalent, per equivalent of acid-producing compound, of the amine. Generally, the maximum amount of amine present will be about 2 moles of amine per equivalent of succinic acid-producing compound. For the purposes of this invention, an equivalent of the amine is that amount of the amine corresponding to the total weight of amine divided by the total number of nitrogen atoms present. Thus, octyl amine has an equivalent weight equal to its molecular weight; ethylene diamine has an equivalent weight equal to one-half its molecular weight; and aminoethyl piperazine has an equivalent weight equal to one-third its molecular weight. The number of equivalents of succinic acid-producing compound depends on the number of carboxylic functions present in the hydrocarbon-substituted succinic acid-producing compound. Thus, the number of equivalents of hydrocarbon-substituted succinic acid-producing compound will vary with the number of succinic groups present therein, and generally, there are two equivalents of acylating reagent for each succinic group in the acylating reagents. Conventional techniques may be used to determine the number of carboxyl functions (e.g., acid number, saponification number) and, thus, the number of equivalents of acylating reagent available to react with amine. Additional details and examples of the procedures for preparing these acylated amines are included in, for example, U.S.Patents 3, 172,892; 3,219,666; 3,272,746; and 4,234,435, the disclosures of which are hereby incorporated by reference. The acylated amine is then reacted with at least one boron compound selected from the class consisting of boron trioxides, boron halides, boron acids, boron amides and esters of boron acids. The amount of boron compound reacted with the acylated amine intermediate generally is sufficient to provide from about 0.1 atomic proportion of boron for each mole of the acylated amine up to about 10 atomic proportions of boron for each atomic proportion of nitrogen of said acylated amine. More generally the amount of boron compound present is sufficient to provide from about 0.5 atomic proportion of boron for each mole of the acylated amine to about 2 atomic proportions of boron for each atomic proportion of nitrogen used. The boron compounds that are useful 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., H 3 BO 3 ), tetraboric acid (i.e., H 2 B 4 O 7 ), metabolic acid (i.e., HBO 2 ), 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 cyclohex¬ anol, 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)-sub- stituted 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 reaction of the acylated amine with the boron compounds can be effected simply by mixing the reactants at the desired temperature. The use of an inert solvent is optional although it is often desirable, especially when a highly viscous or solid reactant is present in the reaction mixture. The inert solvent may be a hydrocarbon such as benzene, toluene, naphtha, cyclohexane, n-hexane, or mineral oil. The temperature of the reaction may be varied within wide ranges. Ordinarily it is preferably between about 50°C and about 250°C. Li some instances it may be 25°C or even lower. The upper limit of the temperature is the decomposition point of the particular reaction mixture and/or product. The reaction is usually complete within a short period such as 0.5 to 6 hours. After the reaction is complete, the product may be dissolved in the solvent and the resulting solution purified by centrifugation or filtration if it appears to be hazy or contain insoluble substances. Ordinarily the product is sufficiently pure so that further purification is unnecessary or optional. The reaction of the acylated amine with the boron compounds results in a product containing boron and substantially all of the nitrogen originally present in the acylated amine reactant. It is believed that the reaction results in the formation of a complex between boron and nitrogen. Such complex may involve in some instances more than one atomic proportion of boron with one atomic proportion of nitrogen and in other instances more than one atomic proportion of nitrogen with one atomic proportion of boron. The nature of the complex is not clearly understood. Inasmuch as the precise stoichiometry of the complex formation is not known, the relative proportions of the reactants to be used in the process are based primarily upon the consideration of utility of the products for the purposes of this invention. In this regard, useful products are obtained from reaction mixtures in which the reactants are present in relative proportions as to provide from about 0.1 atomic proportions of boron for each mole of the acylated amine to about 10 atomic proportions of boron for each atomic proportion of nitrogen of said acylated amine that is used. Useful amounts of reactants are such as to provide from about 0.5 atomic proportion of boron for each mole of the acylated amine to about 2 atomic proportions of boron for each mole of acylated amine. To illustrate, the amount of a boron compound having one boron atom per molecule to be used with one mole of an acylated amine having five nitrogen atoms per molecule is within the range from about 0.1 mole to about 50 moles, preferably from about 0.5 mole to about 10 moles. In one embodiment, these borated acylated amines are useful as component (i) in the formation of the organometallic complexes of the invention. In another embodiment, these borated acylated amines are useful as the organometallic complexes of the invention. (20) Phosphorus-Containing Acylated Amines Component (i) can be a phosphorus-containing acylated amine. These compounds are prepared by the reaction of (P-l) at least one carboxylic acid acylating agent, (P-2) at least one amine characterized by the presence within its structure of at least one H-N=group, and (P-3) at least one phospho- rus-containing acid of the formula In Formula (P-3-1) each X 1 , X 2 , X 3 and X 4 is independently oxygen or sulfur, each m is zero or one, and each R 1 and R 2 is independentty a hydrocarbyl group. The carboxylic acylating agent (P-l) and amine (P-2) are described above with respect to the preparation of borated acylated amines. The phosphorus- containing acids (P-3) include the following: 1. Dihydrocarbyl phosphinodithioic acids corresponding to the formula 2. S-hydrocarbyl hydrocarbyl phosphonotrithioic acids corresponding to the formula 3. O-hydrocarbyl hydrocarbyl phosphonodithioic acids corresponding to the formula 4. S,S-dihydrocarbyl phosphorotetrathioic acids corresponding to the formula 5. O,S-dihydrocarbyl phosphorotrithioic acids corresponding to the formula O \ P-SH R^ 6. O,O-dihydrocarbyl phosphorodithioic acids corresponding to the formula Useful acids of the formula are readily obtainable by the reaction of phosphorus pentasulfide (P S 5 ) and an alcohol or a phenol. The reaction involves mixing at a temperature of about 20 to about 200°C, four moles of alcohol or a phenol with one mole of phosphorus pentasulfide. Hydrogen sulfide is liberated in this reaction. The oxygen- containing analogs of these acids are conveniently prepared by treating the dithioic acid with water or stream which, in effect, replaces one or both of the sulfur atoms. Useful phosphorus-containing acids are phosphorus- and sulfur- containing acids. These acids include those acids wherein at least one X 1 or X 2 is sulfur, and more preferably both X 1 and X 2 are sulfur, at least one X 3 and X 4 is oxygen or sulfur, more preferably both X 3 and X 4 are oxygen and m is 1. Mixtures of these acids may be employed. Each R 1 and R 2 is independentty a hydrocarbyl-based group that is preferably free from acetylenic and usually also from ethylenic unsaturation and have from about 1 to aobut 50 carbon atoms, preferably from about 1 to about 30 carbon atoms, and more preferably from about 3 to about 18 carbon atoms. In one embodiment each R 1 and R 2 is the same or different and has from about 4 to about 8 carbon atoms. Each R 1 and R 2 can be, for example, isopropyl, isobutyl, 4-methyl-2-pentyl, 2-ethylhexyl, iso-octyl, etc. Each R 1 and R 2 can be identical to each other, although they may be different and either or both may be mixtures. Each R 1 and R 2 is preferably alkyl, and most desirably branched alkyl. The reaction to form the phosphorus-containing acylated amines may be carried out by mixing the components (P-l), (P-2) and (P-3) in any order. All three reactants may be mixed at room temperature and heated to a temperature above about 80°C to effect acylation. The reaction may likewise be carried out by first reacting components (P-2) and (P-3) and then acylating the intermediate product with component (P-l), or by acylating the component (P-2) with component (P-l) and then reacting the acylated amine with component (P- 3). The preferred temperature for carrying out the acylating is between about 100°C to about 300°C, preferably about 150°C and 250°C. The acylating is accompanied by the formation of water. The removal of the water formed can be effected by heating the reaction mixture to 100° C or higher. It may be facilitated by blowing the reaction mixture with an inert gas such as nitrogen during such heating. It may be facilitated also by the use in the reaction mixture of an inert solvent which forms a co-distillable azeotropic mixture with water. Examples of such solvents are benzene, n- hexane, toluene, xylene, etc. The use of such solvents permits the removal of water at a substantially lower temperature, e.g., 80°C. The relative proportions of reactants to be used in the process are based upon the stoichiometry of the reaction involved in the process and the utility of the products obtained therefrom for the purpose of this invention. The minimum amounts of components (P-l) and (P-3) to be used are about 0.5 equivalent of each of said components (P-l) and (P-3) for each mole of component (P-2). The maximum amounts of components (P-l) and (P-3) to be used are based on the total number of equivalents of component (P-2) used. For purposes of making these phosphorous-containing acylated amines the number of equivalents of an amine (P-2) is based on the number of HN< groups in such amine. An equivalent weight of an amine is the total weight of amine divided by the total number of HN< groups present. Thus, ethylene diamine has an equivalent weight equal to one-half its molecular weight; and tetraethylene pentamine has an equivalent weight equal to one-fifth its molecular weight. Also, for example, the equivalent weight of a commercially available mixture of amines can be determined by dividing the atomic weight of nitrogen (14) by the weight percent of nitrogen contained in the amine. Therefore, an amine mixture having a %N of 34 would have an equivalent weight of 41.2. The number of equivalents of an amine can be determined by dividing its total weight by its equivalent weight. The number of equivalents of acylating agent (P-l) depends on the number of carboxylic functions (e.g., carboxylic acid groups or functional derivatives thereof) present in the acylating agent. Thus, the number of equivalents of acylating agents will vary with the number of carboxy groups present therein. In determining the number of equivalents of acylating agents, those carboxyl functions which are not capable of reacting as a carboxylic acid acylating agent are excluded. In general, however, there is one equivalent of acylating agent for each carboxy group in the acylating agents. For example, there would be two carboxy groups in the acylating agents derived from the reaction of one mole of olefin polymer and one mole of maleic anhydride. Conventional techniques are readily available for determining the number of carboxyl functions (e.g., acid number, saponification number) and, thus, the number of equivalents of acylating agent available to react with amine. The equivalent weight of component (P-3) can be determined by dividing the molecular weight of component (P-3) by the number of -PXXH garoups. These can usually be determined from the structural formula of component (P-3) or empirically through well known titration procedures. The number of equivalents of component (P-3) can be determined by dividing the weight of component (P-3) by its equivalent weight. The maximum combined equivalents of components (P-l) and (P-3) which can react with one mole of component (P-2) is equal to the number of HN< groups. If an excess of components (P-l) and (P-3) is used, this excess will not take part in the reaction. On the other hand, if the total amount of components (P-l) and (P-3) used is less than the maximum amount, the products will contain unreacted free amino nitrogen atoms. Useful products are those obtained by the use of components (P-l) and (P-3) in relative amounts within the limits of ratio of equiavalents from about 0.5:4.5 to about 4.5:0.5. A specific example illustrating the limits of the relative proportions of the reactants is as follows: one mole of a tetraalkylene pentamine is reacted with from about 0.5 to about 4.5 equivalents of a polyisobutene-substituted succinic anhydride and from about 0.5 to about 4.5 equivalents of a phosphorodithioic acid. (21) Pvrrole Derivatives Component (i) can be a pyrrole derivative represented by the formula In Formula (LIJ.T 1 is OH, N^, NR^ COOR, SH, or C(O)H, wherein R is H or a hydrocarbyl group, preferably a lower alkyl group. Each of the ring carbon atoms can be substituted with hydrocarbyl groups, preferably lower alkyl groups. (22) Pprphyrm Component (i) can be one or more porphyrins. The porphyrins are a class of heterocyclic compounds containing 4 pyrrole rings united by methylene groups. These compounds may be represented by the formula In Formula (LU), R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are independentty H or hydrocarbyl groups of preferably up to about 200 carbon atoms, more preferably up to about 100 carbon atoms, more preferably up to about 50 carbon atoms, more preferably up to about 30 carbon atoms, more preferably up to about 10 carbon atoms. In one embodiment each of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 and R 8 are independentty H, lower alkyl, lower alkenyl, lower hydroxy-substituted alkyl, or -COOH-substituted lower alkyl. Examples include: pyrroporphyrin, rhodoporphyrin, phylloporphyrin, phylloerythrin, dueteroporphyrin, etioporphyrin HI, protoporphyrin, hematoporphyrin, mesoporphyrin IX, coproporphyrin, uroporphyrin and bilirubin. (23) Svlfpnic Acids Component (i) can be a sulfonic acid represented by the formula R 1 SO 3 H (LIU) In Formula (LIIT^R 1 is a hydrocarbyl group of preferably up to about 200 carbon atoms, more preferably up to about 100 carbon atoms, more preferably up to about 60 carbon atoms, more preferably from about 10 to about 60 carbon atoms. The sulfonic acids are characterized by the presence of the sulfo group -SO 3 H (or -SO 2 OH) and can be considered derivatives of sulfuric acid with one of the hydroxyl groups replaced by an organic radical. Compounds of this type are generally obtained by the treatment of petroleum fractions (petroleum sulfonates). Because of the varying natures of crude oils and the particular oil fraction used, sulfonates generally constitute a complex mixture. Useful sulfonates are those having an alkaryl group, i.e., alkylated benzene or alkylated naphthalene. Illustrative examples of sulfonic acids include dioctyl benzene sulfonic acid, dodecyl benzene sulfonic acid, didodecyl benzene sulfonic acid, dinonyl naphthalene sulfonic aicd, dilauryl benzene sulfonic acid, lauryl cetyl benzene sulfonic acid, polyolefin alkylated benzene sulfonic acid such as polybutylene and polypropylene, etc. Further details regarding sulfonic acids may be found in Kirk-Othmer, "Encyclopedia of Chemical Technology", Second Edition, 1969, Vol.19, pp.311 to 319 and in "Petroleum Sulphonates" by R. Leslie in Manuracturing Chemist, October 1950 (XXI, 10) pp. 417-422. (24) EDTA Derivatives Component (i) can be an ethylene diamine tetraacetic acid (EDTA) derivative represented by the formula In Formula (LW),ΕL l , R 2 , R 3 and R 4 are independently H or hydrocarbyl groups of preferably up to about 200 carbon atoms, more preferably up to about 100 carbon atoms, more preferably up to about 50 carbon atoms, more preferably up to about 30 carbon atoms, more preferably up to about 20 carbon atoms. In one embodiment, R 1 , R 2 , R 3 and R 4 are independentty H or lower aliphatic hydrocarbyl groups, preferably H or lower alkyl groups.

Reaction Formine the Oreanometallic Complex The reaction by which the organometallic complexes of this invention are formed from components (i) and (ii) may be effected simply by mixing the reactants at the desired temperature. The reaction can be carried out at a temperature of at least about 80°C. In some instances the reaction temperature may be as low as room temperature such as about 20°C. The upper limit for the reaction temperature is the decomposition point of the reaction mixture although a temperature higher than 250°C is rarely necessary. The reaction is preferably carried out in the presence of a diluent or solvent in which the reactants are soluble or the product is soluble. The solvent may be any fluid, inert solvent such as benzene, xylene, toluene, kerosene, mineral oil, chlorobenzene, dioxane or the like. The relative amounts of the components (i) and (ii) vary within wide ranges. Usually at least about 0.1 equivalent of component (ii) is used per equivalent of component (i). The amount of component (ii) preferably can be from about 0.05 to about 1, more preferably from about 0.1 to about 0.4 equiva¬ lents of component (ii) per equivalent of component (i). The equivalent weight of component (i) is based on the number of functional groups in component (i) that are capable of forming a complex with the metal in component (ii). Thus, the weight of an equivalent of propylene tetramer nitrophenol is equal to one- half its molecular weight. The equivalent weight of component (ii) is based on the number of metal atoms in its molecule. Thus, the weight of an equivalent of cuprous oxide is one-half its molecular weight and the weight of an equivalent of cupric hydroxide is its molecular weight. Also, the relative amount of component (ii) is based to some extent upon the coordination number of the metal of in component (ii) reactant. For instance, as many as six equivalents of component (i) may combine with one equivalent of a metal reactant in which the metal has a coordination number of six. The product obtained by the reaction of component (i) with component (ii) is an "organometallic complex". That is, it results from the combination of the functional groups in component (i) with the metal of component (ii) by means of the secondary valence of the metal. The precise nature of the organometallic complex is not known. For purposes of this invention it is only necessary that such complexes be sufficiently stable in diesel fuel to permit use in a diesel engine equipped with an exhaust system particulate trap to lower the ignition temperature of exhaust particles collected in said trap. The inventive organometallic complex is other than copper dihydrocarbyl thiophosphate, copper dihydrocarbyl dithiophosphate, copper dithiocarbamate, copper sulphonate, copper phenate or copper acetyl acetonate. In one embodiment the organometallic complex is other than a transition metal complex of an aromatic Mannich in combination with a Schiff base, the Mannich being derived from an aromatic phenol, an aldehyde or ketone, and a hydroxyl- and/or thiol-containing amine. In one embodiment the organometallic complex is other than a transition metal complex of an aromatic Mannich in combination with an oxime, the Mannich being derived from an aromatic phenol, an aldehyde or ketone, and a hydroxyl- and/or thiol-containing amine.
