摘要: The invention is a novel composition of alkylated phenyl phosphate esters comprising by weight 1% to 20% trialkylphenyl phosphate, 10% to 50% dialkylphenyl monophenyl phosphate, 15% to 60% monoalkylphenyl diphenyl phosphate and less than 2% triphenyl phosphate and a process for preparing the composition comprising passing the composition at least once through a thin film evaporator at a temperature of about 200.degree. C. to about 250.degree. C. at a pressure sufficiently less than 5 kPa to evaporate about 5% to about 30% of the composition.

摘要: The antiwear properties of synthetic ester lubricants intended for use at high temperatures (150.degree. C. to 350.degree. C.) are improved by adding to the lubricants a hydrocarbon insoluble, synthetic ester soluble, aryl diphosphate ester composition containing a major amount of an aryl diphosphate ester of the formula: ##STR1## wherein Ar is unsubstituted or alkyl (C.sub.1 -C.sub.12) substituted arylene and R is unsubstituted or alkyl (C.sub.1 -C.sub.12) substituted aryl.
