Method for the preparation of esters of a non-reducing sugar and one or more fatty acids

摘要

Method for the preparation of esters of a non-reducing sugar like sucrose and one or more fatty acids by transesterification of a non-reducing sugar with one or more fatty acid esters in at first a worm shaft reactor operating at elevated temperature and pressure and then in a second reactor operating at reduced pressure and elevated temperature. Such esters of a non-reducing sugar and fatty acids, in particular the monoesters and diesters are valuable solid surfactants, which are non-toxic, odorless, tasteless, non-irritating to the skin and hydrolyze in the human and animal tract to normal good products.
