ABSTRACT:
An improved solvent-free transesterification process for producing polyol fatty acid polyesters is disclosed. In this process, a mixture of a polyol, a fatty acid methyl, 2-methoxy ethyl or benzyl ester, an alkali metal fatty acid soap, and potassium carbonate, sodium carbonate or barium carbonate as a catalyst is heated to form a homogeneous melt. To this melt is subsequently added excess fatty acid methyl, 2-methoxy ethyl or benzyl ester, yielding the desired polyol fatty acid polyesters.
