Abstract (en)
[origin: WO2006010468A1] The invention relates to a method for producing cellulose derivatives containing amino groups by reacting alkalized cellulose or alkalized cellulose derivatives with reagents of general formula X-(CH<SUB>2</SUB>)<SUB>n</SUB>-NR<SUB>1</SUB>R<SUB>2</SUB> in which: X represents a leaving group, preferably chlorine, bromine, iodine or a sulfonic acid radical R'SO<SUB>3</SUB>, R' representing an aromatic or aliphatic radical with 1 - 24 C atoms, e.g. para-toluyl or methyl; n must be at least 2; radicals R<SUB>1</SUB> and R<SUB>2</SUB>, independent of one another, represent aliphatic or branched or cyclic alkyl substituents or aryl substituents with 1 - 24 C atoms, these substituents being optionally substituted by heteroatoms, or represent H, or two radicals R<SUB>1</SUB> and R<SUB>2</SUB>, together with the nitrogen, can form a ring. The invention is characterized in that water is used as a reaction medium, and the ratio of cellulose to water ranges from 1: 5 to 1: 40 mol per mol of anhydroglucose unit (AGU). The invention also relates to cellulose derivatives containing amino groups with a specified total substitution and to the use thereof in cosmetic formulations, in treating water or in the manufacturing of paper.
