摘要：

The preparation von N-alkanoyl-polyhydroxyalkylamines I in which ##STR1## in which Z stands for the polyhydroxyalkyl radical of a monosaccharide or oligosaccharide,R.sup.1 denotes hydrogen or C.sub.1 -C.sub.8 alkyl andR.sup.2 denotes C. sub.1 -C.sub.21 alkyl, by the reaction of polyhydroxyalkylamines of the general formula IIZ--NH--R.sup.1 (II), with alkyl carboxylates of the general formula III ##STR2## in which R. sup.3 denotes a C.sub.1 -C.sub.4 alkyl radical,in the presence of a basic catalyst, in which(a) all of the ester III is placed in the reactor and is heated to the reaction temperature, and the amine II is metered in in the form of a melt while the reaction proceeds, while alcohol R.sup.3 --OH formed is continuously removed by distillation,(b) the reaction is carried out at a temperature of from 55&deg; to 110&deg; C., and< P>(c) the reaction is carried out in the absence of organic solvents.
