Title:
SEPARATING AGENT FOR OPTICAL ISOMERS
Document Type and Number:
WIPO Patent Application WO/2016/182083
Kind Code:
A1
Abstract:
Provided is a separating agent for optical isomers, which is configured of a novel xylan derivative and a carrier. Specifically provided is a separating agent for optical isomers, which is configured of a carrier and a xylan-phenylcarbamate derivative that is obtained by substituting a hydroxy group of xylan with a group represented by formula (I) or (II). (In formula (I), R1 represents a halogen or an alkyl group having 1-5 carbon atoms; and the position of substitution of the R1 moiety is the meta position or the para position. In formula (II), each of R2 and R3 independently represents a halogen or an alkyl group having 1-5 carbon atoms, and R2 and R3 are groups different from each other.)
