Abstract

Nitrogen-containing derivatives of hexoses are prepared by reacting hexoses (or polysaccharides which become hexoses under the reaction conditions), in the presence of a dehydrating agent with organic compounds of the general formula <FORM:0653775/IV (b)/1> in which R represents hydrogen or an alkyl, aryl or alkaryl group and X represents an oxygen or sulphur atom or the =NH group, or with melamines. Sulphuric acid, zinc chloride and phosphoric acid are suitable condensing agents. The reactants are conveniently stirred together in molten condition, preferably in the presence of not more than 20 per cent of water. In examples: (1) glucose hydrate is reacted with urea to produce a glucose ureide; (2) cane sugar is reacted with urea in the presence of some water; (3) the urea of (2) is replaced by thiourea; (4) glucose hydrate is reacted with guanidine, and (5) glucose hydrate is reacted with melamine.ALSO:Cellulosic textile materials are crease-proofed and shrink-proofed by treating them in the presence of an aldehyde with a nitrogen-containing derivative of a hexose prepared by reacting a hexose (or polysaccharide which becomes a hexose under the reaction conditions), in the presence of a dehydrating agent with a compound of the general formula <FORM:0653775/IV (c)/1> in which R is hydrogen or an alkyl, aryl or alkaryl group and X is an oxygen or sulphur atom or the =NH group. Examples are given of the reaction of glucose hydrate with urea, thiourea, guanidine or melamine, and of cane sugar with urea.
