摘要：
The antiwear properties of synthetic ester lubricants intended for use at high temperatures (150 DEG C. to 350 DEG 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: wherein Ar is unsubstituted or alkyl (C1-C12) substituted arylene and R is unsubstituted or alkyl (C1-C12) substituted aryl.
