ABSTRACT:
The present invention relates, generally, to a high temperature stable mixed polyol ester lubricant composition partly containing an aromatic carboxylic acid ester and a process of making the same. Typically, the aromatic acid ester is benzoic acid, and the lubricant composition preferably comprises a mixture of linear C5, i-C9, and linear C7-10aliphatic carboxylic acid. The esters are preferably formed from an aliphatic polyol. These mixed polyol esters are useful in aero-derived gas turbine engines.
