摘要

PURPOSE: A synthetic ester offering a higher degree of hydrolytic stability when compared to Gateway's Syn-ester is provided which is achieved by the incorporation of an additive which is the heptanoic acid ester of cyclohexane dimethanol and other esters embodying similar structures. CONSTITUTION: A various derivatives which are effective as extreme pressure additives include those which fall within the generic description (1), wherein R1 through R4 are independently selected from the group hydrogen and C1-24 hydrocarbyl groups, and R5 and R6 are independently preferably selected from the group C3-6 hydrocarbyl groups.
