| 摘要 |
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.
