Carbohydrate-derived surfactants and their precursors.

摘要

A method for the manufacture of N,N dialkylglycamine compounds of general formula R2NR1R3(I) by reacting a secondary amine of general formula R2NHR3 (II) in which R2 is a straight or branched chain alkyl or hydroxyalkyl group having from 1 to 4 carbon atoms and R3 is a residue from a monosaccharide, with an alkali metal or alkaline earth metal aliphatic sulphate, R1SO4M, in which R1 is a straight or branched chain alkyl or alkenyl group having from 8 to 24 carbon atoms. The betaine, suphobetaine and N-oxidised derivatives of (I) are provided for use as mild surfactants.
