Title:
METHOD FOR PRODUCING ALKYL-N-ACETYLGLUCOSAMINIDE
Document Type and Number:
WIPO Patent Application WO/2015/194199
Kind Code:
A1
Abstract:
[Problem] To provide a method for obtaining an alkyl-N-acetylglucosaminide with a low content of N-acetylglucosamine, which is an impurity, inexpensively, easily, and efficiently. [Solution] This method for producing an alkyl-N-acetylglucosaminide comprises a step for reducing the content of N-acetylglucosamine by bringing a mixture of an alkyl-N-acetylglucosaminide and N-acetylglucosamine into contact with a strongly basic anion-exchange resin.
