Abstract
The invention relates to a process for the preparation of fatty acid partial esters of polyols, the fatty acid partial esters thus obtainable, and their use. The fatty acid partial esters (I) of polyols having at least 4 C atoms, at least one primary and at least one secondary alcohol group of the starting polyols are obtained in a process, where in a first process step the polyols are reacted with a fatty acid or a fatty acid derivative to give a fatty acid partial ester (II) and in a second process step the fatty acid partial esters (II) obtained are subjected to a selective enzymatic cleavage of primary ester groups.
Claims35
A process for the preparation of fatty acid partial esters of polyols having at least 4 carbon atoms, at least one primary and at least one secondary alcohol of initial polyols, comprising reacting polyols with a fatty acid or a fatty acid derivative to provide a fatty acid partial ester and subjecting said fatty acid partial ester to a selective enzymatic reaction wherein primary ester groups of said fatty acid partial ester are cleaved.
