Esters formed from polyol, C-Cbranched chain fatty acid, and/or C-Ccyclic fatty acid are useful as a friction modifier for lubricants. Monomer is a preferred source for these fatty acids.

Fatty acid esters and uses thereof

Secondary alcohol esters of hydroxyacids, e.g., ricinoleate esters of secondary alcohols, are prepared by reacting an ester of a hydroxyacid with a secondary alcohol, in the presence of an organometallic transesterification catalyst. Under these reaction conditions, a high proportion of the starting ester of a hydroxyacid is converted into a secondary alcohol ester of the hydroxyacid, while minimizing the formation of by-products including estolide. The product esters and composition containing same may be used as a lubricity agent or as a friction modifier in a lubricant composition.
