Abstract:
A process for the production of complex polyol ester with high yield, which comprises:reacting a polyol with mono- and polybasic acids in the presence of a catalyst to produce a reaction blend containing complex esters, treating the reaction blend with a base to neutralize the acid components in the reaction blend, wherein the base is comprised of a tertiary amine in an organic solvent and the tertiary amine has the formula R1R2R3N, wherein R1, R2 and R3 represent independent alkyl groups with 1-5 carbon atoms, and aryl groups, and R1 and R2 can together form a substituted or unsubstituted ring with 5-10 carbon atoms, and recovering the complex esters from the reaction blend treated in this manner.
