Title:
PRACTICAL CHIRAL ZIRCONIUM CATALYST
Document Type and Number:
WIPO Patent Application WO/2003/076072
Kind Code:
A1
Abstract:
A practical chiral zirconium catalyst, characterized in that a chiral zirconium catalyst is fixed on a zeolite. The practical chiral zirconium catalyst can maintain high catalyst activity after the storage for a long period of time, is stable also in air, can be recovered and reused after reaction, and thus exhibits high practicality.
