Title:
光学異性体用分離剤及びその製造法
Document Type and Number:
Japanese Patent JP4320068
Kind Code:
B2
Abstract:
The invention provides separating agents for optical isomers which have a high optical resolving power inherent in polysaccharide derivatives and high solvent resistance, and which can be produced through short process steps; a process for producing the same, and a method for separating optical isomers. The invention also provides separating agents for optical isomers, wherein the surface of a polysaccharide derivative supported on a carrier or the surface of a pulverized or granulated polysaccharide derivative is coated with a polymer, which are produced by supporting the polysaccharide derivative on the carrier and then coating the surface thereof with the polymer to thereby immobilize the polysaccharide derivative on the substrate, or by grinding or spheroidizing the polysaccharide derivative and then coating the surface thereof with a polymer.
