A method for the production of partial esters of glycerol and condensed glycerols with fatty acids

摘要

Partial esters of glycerol and condensed glycerols with fatty acids with 2 to 18 carbon atoms are obtained by enzymatic esterification using a lipase from Candida cylindracea or from Rhizopus arrhizus in the presence of 5 to 20% by weight of water based on the reactants. When the reaction is carried out in the presence of a fixed oil or mineral oil the resulting esterification mixture is suitable as emulsifier system.
