Abstract:

The chiral stationary pahse of 3,5-dimethylphenylcarbamates of cellulose chemically bonded to 3-aminopropyl silica gel at the 6-position of the glucose units was prepared. The racemates of tebuconazole were resolved on the new immobilized chiral stationary phase, and the influences of modifiers(alcohols, THF and chloroform) in the mobile phase on the resolution were investigated. The chromatographic conditions were optimized. The results show that the new immobilized chiral stationary phase exhibits a good stereoselectivity to tebuconzole. The best resolution of 1.51 of tebuconazole was obtained by using hexane/2-propanol/ THF(volume ratio 90:5:5) as the mobile phase on a 150 mm column.

Key words: Immobilization, Chiral stationary phase, Chiral resolution, Tebuconazole
