Abstract

A thermal oxidatively stable synthetic fluid composition is disclosed. The composition is essentially comprised of an aromatic carboxylic acid ester of general formula (I), wherein Ar is an aromatic moiety, R is a neo hydrocarbyl group containing from about 5 to about 18 carbon atoms, with the proviso that R is not a cycloalkyl substituted neo hydrocarbyl group, R1 is a mono, di, tri or tetra functional hydrocarbyl group containing from 1 to about 18 carbons atoms, n is an integer from about 2 to about 4 and represents the total number of carboxylic acid ester groups on the aromatic moiety, a is an integer from about 1 to about 4, when a is 1 R1 is monovalent, when a is 2 R1 is divalent, when a is 3 R1 is trivalent and when a is 4 R1 is tetravalent, R2 is a hydrocarbyl group derived from a diol containing from about 2 to about 18 carbon atoms and x is an integer from 0 to about 4.
