Title:
METHOD OF SEPARATING OPTICAL ISOMERS
Document Type and Number:
WIPO Patent Application WO/1995/029142
Kind Code:
A1
Abstract:
A method of separating optical isomer, by which optical resolution of an optical isomer mixture can be efficiently conducted by using a packing material which is inexpensive per se and has an excellent ability to separate optically active compounds in place of expensive silica gel and using a pseudo-moving-bed chromatographic separator. This method is characterized by the use of particles of a polysaccharide derivative, preferably ester derivative and/or carbamate derivative as the packing material for optical resolution.
