Abstract
According to the present invention, in the first instance, new aminopolyols, which can be obtained from the disaccharides isomaltose, isomaltulose and .alpha.-D-glucopyranosyl (1.fwdarw.1)-D-fructose, are prepared. These compounds, designated as isomaltamines and having the formulae: ##STR1## as well as mixtures of the same, are produced by the reductive amination of the aforementioned saccharides by means of ammonia or hydrazine compounds in the presence of catalysts, such as Raney nickel, and hydrogen, or by means of complex metallic hydrides, such as sodium borohydride, in solution or suspension. The invention relates, furthermore, to the N-acyl derivatives of the individual isomaltamines or their mixtures as well as to the production of the N-acylates by a selective N-acylation. Depending upon the nature of the acyl radical, these acylates can be used for example, as surfactants or (similarly to N-acrylamide) for the production of polymers.
