SEPARATING AGENT FOR OPTICAL ISOMERS AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/1999/018052

Kind Code:

A1

Abstract:

A separating agent for optical isomers which has a high suitability for use as a reagent for optical resolution inherent in polysaccharide derivatives and also a solvent resistance and is capable of being produced through short process steps; and a method of separating optical isomers. The separating agent comprises a polysaccharide derivative coated with a polymer and supported on a carrier, or pulverized or sphered. It is produced by supporting a polysaccharide derivative on a carrier and then coating the surface with a polymer to immobilize the derivative on the carrier or by pulverizing or sphering a polysaccharide derivative and then coating the surface with a polymer.
