SYNTHESIS OF HIGHER POLYOL FATTY ACID POLYESTERS

摘要

SYNTHESIS OF HIGHER POLYOL FATTY ACID POLYESTERS Harry M. Taylor and George P. Rizzi A solvent-free transesterification comprising the steps of (1) heating a mixture of a polyol, a fatty acid lower alkyl ester, an alkali metal fatty acid soap, and a basic catalyst to form a homogenous melt; and (2) subsequently adding to the reaction product of step (1) excess fatty acid lower alkyl esters yields polyol fatty acid polyesters.
