Abstract:
Process for preparing .beta.-hydroxyalkylamides of the general formula IV: ##STR11##where A is a chemical bond or a polyvalent organic group or, if n'=0, hydrogen or a monovalent group, where the monovalent or polyvalent organic group is selected from amonG saturated or unsaturated (C1-60) alkyl, cycloalkyl, aryl, carboxyalkenyl, alkoxycarbonylalkenyl or trialkylenamino groups, and R1 is hydrogen or a C1-C5-alkyl group and R2 is hydrogen, a C1-C5-alkyl group or: ##STR12##and n is an integer from 1 to 10 and n' is an integer from 0 to 2, in which the corresponding alkyl esters are reacted with the corresponding .beta.-aminoalcohols in the absence of solvents and in the presence of a basic catalyst and the resulting alcohol is removed, characterized in that, to improve the selectivity, the ratio of equivalents of ester to equivalents of amine is 1:1.001-8, the basic catalyst is destroyed after the aminolysis and the unreacted aminoalcohol is removed by distillation.
