PROCESS FOR PRODUCING CHITIN DERIVATIVE

摘要

A process for producing a chitin derivative having the high ability to asymmetrically identify; and a separatory agent for optical isomers which comprises the chitin derivative as an agent for asymmetric identification. The process for producing a chitin derivative is characterized by converting chitin into a derivative in a mixed solvent comprising lithium chloride and N,N-dimethylacetamide.
