Description: THERMALLY STABLE COMPOSITIONS AND LUBRICANTS A FUNCTIONAL FLUIDS CONTAINING THE SAME Technical Field of the Invention This invention relates to compositions which a useful as additives for lubricants and functional fluids These additives provide lubricants and functional flui with thermal stability and improved antiwear, extre pressure, load-carrying and/or corrosion-inhibiting proper ties. Introduction to the Invention Historically antiwear hydraulic fluids have con tained zinc in the form of zinc dithiophosphates. Thes hydraulic fluids typically have excellent thermal stabilit and antiwear properties. However, in recent years ther has been growing concern about the accumulation in the wor place and environment of heavy metals such as zinc. Thi concern has lead to the demand for hydraulic fluids whic contain only ashless antiwear agents. Ashless antiwea agents are available but often fluids containing thes agents lack thermal stability. One test which measures lubricant's thermal stability is the Cincinnati Milicro test. Hydrocarbyl phosphites are antiwear agents whic are useful in replacing zinc dithiophosphates in hydrauli fluids. However, under high temperature operating condi tions, phosphites form products which are corrosive to th yellow metal components in the hydraulic systems. Withou a means to stabilize phosphites, they are ineffective i replacing zinc dithiophosphates in hydraulic fluids. PCT publication WO 89/04358 relates to a composi tion comprising (A) a neutral or basic metal salt or boron containing neutral or basic metal salt of at least on acidic organic compound, (B) a metal deactivator and (C) sulfur- and/or phosphorus-containing compound. Thes compositions are used in lubricants and functional fluids βimm rγ o the Invention This invention relates to a composition, compris ing: (A) at least one basic alkali or alkaline eart metal salt of an acidic organic compound; (B) at least one metal deactivator other tha dimercaptothiadiazole or derivatives thereof; and (C) at least one hydrocarbyl phosphite, wherei the equivalents of (A) based on total base number to th equivalents of (C) based on phosphorus atoms is at leas one, provided that the composition is free of zin dithiophosphate and provided that when (A) is an overbased magnesiu salicylate then the composition contains (D) up to abou 0.40% by weight of a sulfur-, phosphorus-, or sulfur- an phosphorus-containing antiwear agent. These compositions are useful as additives for lubricants and functional fluids, particularly hydraulic fluids, gear oils, greases and the like. The lubricants and fluids having this particular combination of components have improved thermal stability and do not contain zinc dithiophosphate. These lubricants and fluids are also not corrosive to the hydrau¬ lic system components. Description of the Invention The term "hydrocarbyl" includes hydrocarbon, as well as substantially hydrocarbon, groups. Substantially hydrocarbon describes groups which contain non-hydrocarbon substituents which do not alter the predominately hydrocar- bon.nature of the group. Examples of hydrocarbyl groups include the following: (1) hydrocarbon substituents, that is, aliphatic (e.g., alkyl or alkenyl) , alicyclic (e.g., cycloalkyl, cycloalkenyl) substituents, aromatic-, aliphatic- and alicyclic-substituted aromatic substituents and the like a well as cyclic substituents wherein the ring is complete through another portion of the molecule (that is, fo example, any two indicated substituents may together for an alicyclic radical) ; (2) substituted hydrocarbon substituents, tha is, those substituents containing non-hydrocarbon group which, in the context of this invention, do not alter th predominantly hydrocarbon substituent; those skilled in th art will be aware of such groups (e.g., halo (especiall chloro and fluoro) , hydroxy, alkoxy, ercapto, alkylmer capto, nitro, nitroso, sulfoxy, etc.); (3) hetero substituents, that is, substituent which will, while having a predominantly hydrocarbo character within the context of this invention, contai other than carbon present in a ring or chain otherwis composed of carbon atoms. Suitable heteroatoms will b apparent to those of ordinary skill in the art and include for example, sulfur, oxygen, nitrogen and such substituent as, e.g., pyridyl, furyl, thienyl, imidazolyl, etc. I general, no more than about 2, preferably no more than one, non-hydrocarbon substituent will be present for every te carbon atoms in the hydrocarbyl group. Typically, ther will be no such non-hydrocarbon substituents in the hydro carbyl group. Therefore, the hydrocarbyl group is purel hydrocarbon. (A) Basic Metal Salts The lubricating compositions of the presen invention contain (A) at least one basic alkali or alkalin earth metal salt of an acidic organic compound. Thes salts are generally referred to as overbased materials. Overbased materials are single phase, homogeneous Newtonia systems characterized by a metal content in excess of tha which would be present according to the stoichio etry o the metal and the particular acidic organic compou reacted with the metal. The amount of excess metal is commonly express in terms of metal ratio. The term "metal ratio" is t ratio of the total equivalents of the metal to the equiv lents of the acidic organic compound. A neutral metal sa has a metal ratio of one. A salt having 4.5 times as mu metal as present in a normal salt will have metal excess 3.5 equivalents, or a ratio of 4.5. The basic salts of t present invention have a metal ratio of about 1.5, mo preferably about 3, more preferably about 7, up to abo 40, preferably about 25, more preferably about 20. The basicity of the overbased materials of t present invention generally is expressed in terms of total base number. A total base number is the amount o acid (perchloric or hydrochloric) needed to neutralize al of the overbased material's basicity. The amount of aci is expressed as potassium hydroxide equivalents. Tota base number is determined by titration of one gram o overbased material with 0.1 Normal hydrochloric aci solution using bromophenolblue as an indicator. Th overbased materials of the present invention generally hav a total base number of at least about 20, preferably abou 100, more preferably about 200. The overbased materia generally have a total base number up to about 600, prefer ably about 500, more preferably about 400. The total bas number is essential to the invention because the inventor have discovered that the ratio of the equivalents o overbased material based on total base number to th equivalents of hydrocarbyl phosphite based on phosphoru atoms must be at least one to make the thermally stabl lubricating compositions of the present invention. Th equivalents of overbased material is determined by th following equation: equivalent weight = (56,100/total bas number) . For instance, an overbased material with a tota base number of 200 has an equivalent weight of 280.5 (eq « 56100/200) . The equivalents of phosphite are determin by dividing the molecular weight of the phosphite by t number of phosphorus atoms in the phosphite. The overbased materials (A) are prepared reacting an acidic material (typically an inorganic acid lower carboxylic acid, preferably carbon dioxide) with mixture comprising an acidic organic compound, a reacti medium comprising at least one inert, organic solve (mineral oil, naphtha, toluene, xylene, etc.) for sa acidic organic material, a stoichiometric excess of a met base, and a promoter.

Accordingly, is to be understood that the aromatic group as represen by "Ar", as well as elsewhere in other formulae in t specification and in the appended claims, can be mononuc ar such as a phenyl, a pyridyl, or a thienyl, or polynuc ar. The polynuclear groups can be of the fused t wherein an aromatic nucleus is fused at two points another nucleus such as found in naphthyl, anthranyl, e The polynuclear group can also be of the linked t wherein at least two nuclei (either mononuclear or poly clear) are linked through bridging linkages to each oth These bridging linkages can be chosen from the gr consisting of alkylene linkages, ether linkages, k linkages, sulfide linkages, polysulfide linkages of 2 about 6 sulfur atoms, etc. The number of aromatic nuclei, fused, linked both, in Ar can play a role in determining the inte values of a and b.
