Abstract
Abstract NEOALKYLPOLYOL ESTERS OF MIXTURES OF STRAIGHT CHAIN FATTY ACIDS OR BRANCHED CHAIN FATTY ACIDS WHICH ARE NOT NEO ACIDS, AN NEOALKYL FATTY ACIDS ARE PREPARED BY A NOVEL PROCESS WHICH RESULTS IN A PRODUCT HAVING SUPERIOR LOW TEMPERATURE PROPERTIES AND OXIDATION STABILITY. THE NOVEL PROCESS OF THIS INVENTION COMPRISES PARTIALLY ESTERIFYING A NEOALKYLPOLYOL WITH A MIXTURE OF STRAIGHT CHAIN OR BRANCHED CHAIN CARBOXYLIC ACIDS AND A NEOALKYL FATTY ACIDS, REMOVING UNREACTED ACID FROM THE MIXTURE BEFORE THE ESTERIFICATION IS COMPLETE, AND ADDING STRAIGHT OR BRANCHED CHAIN FATTY ACID SUFFICIENT TO COMPLETE THE ESTERIFICATION.
