Abstract
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.
