Abstract

Lubricating oil compositions comprise a major proportion of a hydrocarbon lubricating oil and a minor proportion of an amine salt of general formula <FORM:0916505/III/1> in which m and n are from 0-17, m+n being from 9 to 17, R1 is a dimethylene, vinylene, or sulphurized vinylene group, each of the R2 and R3 is a hydrogen atom or an aliphatic group with 1 to 4 carbon atoms, X is oxygen or sulphur and each of R4 and R5 is an aliphatic or cycloaliphatic group with 1 to 12 carbon atoms (see Group IV(b)) for example oleylamine p and stearylamine o,o-di(1,3-dimethyl butyl) phosphorodithioates and oleylamine o,o-di-isopropylphosphorodithioate. Additional ingredients comprising a chlorinated aliphatic hydrocarbon in which a part only of the chlorine has been replaced by a thiocarbonate group, e.g. a chlorinated naphtha reacted with potassium isopropyl xanthate to give a product with 11% sulphur, 16% xanthate and 34% of chlorine; a metal salt of a dithio acid of phosphorus of general formula <FORM:0916505/III/2> where M is zinc barium calcium or magnesium and X is 1 (phosphoric acids) or O (phosphinic acids); and a phosphorized and sulphurized dicyclic terpene obtained by reacting cacene, pinene, camphene and fenchene with a phosphorus sulphide, e.g. phosphorus penta sulphide are used singly or in admixture.ALSO:The invention comprises amine salts of general formula <FORM:0916505/IV (b)/1> in which m and n are integers from 0 to 17, m + n being from 9 to 17, R1 is a dimethylene, vinylene, or sulphurised vinylene group, each of the R2 and R3 is a hydrogen atom or an aliphatic group of 1 to 4 carbon atoms, X is oxygen or sulphur, and each of R4 to R5 is an aliphatic or cycloaliphatic group containing one to twelve carbon atoms, the minimum number of carbon atoms in the two groups being 3 provided that when m + n is 9, each of R4 and R5 may not contain more than 9 carbon atoms. The salts are prepared by the reaction of amines of general formula <FORM:0916505/IV (b)/2> with one or more thiophosphoric acids of formula, <FORM:0916505/IV (b)/3> Lists of amines and thiophosphoric acids are given and examples describe the preparation of oleylamine and stearylamine O,O-di(1,3-dimethylbutyl)phosphorodithioate, and oleylamine O,O - diisopropylphosphorodithioate which are claimed. The compounds are used in lubricating compositions with hydrocarbon lubricating oils with or without additional ingredients (see Group III). Chlorinated aliphatic hydrocarbons in which part of the chlorine has been replaced by a thiocarbonate group; metal salts such as zinc barium calcium and magnesium of a dithio acid of phosphorus e.g. a zinc salt of O,O-di(1,32-dimethylbutyl) dithiophosphoric acid; and a phosphorised and sulphurised dicyclic terpene obtained by reacting phosphorus sulphide with the terpene, e.g. phosphorus pentasulphide reacted with pinene may be used as the additional additives in the compositions.
