Fuel composition comprising triazole-derived acid-esters or ester-amide-amine salts as antiwear additives

An improved fuel composition comprising a major proportion of a liquid hydrocarbon or oxygenated fuel or mixtures thereof and a minor proportion of an additive product of reaction prepared by reacting (1) a triazole or hydrocarbyl substituted triazole with a hydrocarbyl oxide to form a triazole-derived alcohol and thereafter (2) reacting said triazole-derived alcohol with a hydrocarbyl carboxylic anhydride or its acid or acid generating equivalent selected from succinic or phthalic anhydrides or hydrocarbyl substituted succinic or phthalic anhydrides or their acid equivalents to produce substituted hydrocarbyl carboxylic acid-ester derivatives and (3) converting said acid-ester derivatives to their corresponding diester, amide-ester salts by reaction with suitable amine or hydroxy or hydroxyamine compounds and wherein the reactions are carried out at temperatures varying from ambient to about 250.degree. C. under ambient or autogenous pressures, in molar ratios of reactants varying from equimolar to more than molar to less than molar for times sufficient to obtain the desired additive product of reaction.
