Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 109 words
A lubricant composition comprising a major proportion of an oil of lubricating viscosity or grease prepared therefrom and a minor effective proportion of a friction reducing additive consisting of monoamine, diamine or triamine salts or mixtures thereof of diol-derived acid phosphates wherein said diol is a long chain vicinal diol having the following general structure: ##STR3## where R 1 =C 8 -C 30 hydrocarbyl and R 2 =hydrogen or C 1 -C 6 hydrocarbyl and wherein said amines have the following general structure; R.sup.3 (NHR.sup.4).sub.x NH.sub.2 where R 3 =C 8 -C 10 hydrocarbyl or hydrocarbyloxy hydrocarbylene, R 4 =C 2 -C 4 hydrocarbylene and x=0, 1, or 2.
Claim 2
Dependent Claim 109 words
A lubricant composition comprising a major proportion of an oil of lubricating viscosity or grease prepared therefrom and a minor effective proportion of a friction reducing additive consisting of monoamine, diamine or triamine salts or mixtures thereof of diol-derived acid phosphates wherein said diol is a long chain vicinal diol having the following general structure: ##STR3## where R 1 =C 8 -C 30 hydrocarbyl and R 2 =hydrogen or C 1 -C 6 hydrocarbyl and wherein said amines have the following general structure; R.sup.3 (NHR.sup.4).sub.x NH.sub.2 where R 3 =C 8 -C 10 hydrocarbyl or hydrocarbyloxy hydrocarbylene, R 4 =C 2 -C 4 hydrocarbylene and x=0, 1, or 2.
