ethanolamines

Regularities of the reaction of oleic acid with a mixture of ethanolamines have been investigated under non-stationary conditions in the presence of H-form of cation-exchange resin KU-2-8 as a catalyst. The effect of a ratio between reagents and the catalyst on the acid conversion, selectivity and products yield has been determined. N-acylation of mono- and diethanolamines by an oleic acid was found to be more intensive compared with esterification of hydroxy groups of ethanolamine.
