Reaction products of organophosphorus halides with inorganic thiocyanates as load-carrying additives in lubricating oil compositions

DETAILED DESCRIPTION I claim: 1.
A lubricant composition comprising a major proportion of a mineral oil, a synthetic oil or greases thereof and a minor proportion sufficient to impart antiwear and load-carrying characteristics thereto of a product prepared by reacting from about 0.
2 mole to about 1 mole of an organophosphorus halide; having the following generalized formula: ##STR3## where m=3-(n+q), n=3-(m+q) and q=3-(n+m) but not zero, and Y is 0 or S, X is a halide selected from chloride, bromide or iodide and R and R.
sup.
1 may be the same or different and each is a hydrocarbyl group containing from 1 to about 36 carbon atoms selected from alkyl groups having from about 4 to 12 carbon atoms and alkaryl groups comprised of phenyl, naphthyl or anthryl with the alkyl substituents thereof containing from 1 to about 20 carbon atoms; with from about 1 to about 5 moles of an inorganic thiocyanate selected from sodium, potassium or ammonium thiocyanates.
2.
The composition of claim 1 wherein the thiocyanate is ammonium thiocyanate and the organophosphorus halide is an organophosphorus chloride.
3.
The composition of claim 2 wherein the organophosphorus halide is di(nonylphenyl) phosphorochloridate.
4.
The composition of claim 2 wherein the organophosphorus halide is nonylphenyl phosphorochloridite.
5.
The composition of claim 2 wherein the organophosphorus halide is di(nonylphenyl) phosphorochloridite.
6.
The composition of claim 2 wherein the organophosphorus halide is n-octyl phosphorochlorodite.
7.
The composition of claim 2 wherein the organophosphorus halide is dibutyl phosphorochlorodite.
8.
The composition of claim 2 wherein the organophosphorus halide is butyl phosphorochlorodite.
9.
The composition of claim 2 wherein the organophosphorus halide is dioctyl phosphorochlorodite.
10.
The composition of claim 1 wherein the organophosphorus halide is n-octyl phosphorochlorodite and the thiocyanate is potassium thiocyanate.
11.
The composition of claim 2 wherein the organophosphorus halide is dioctyl phosphorochlorodite and the thiocyanate is sodium thiocyanate
