Chiral Stationary Phases for HPLC: Cellulose Tris(3,5-dimethylphenylcarbamate) and Tris(3,5-dichlorophenylcarbamate) Chemically Bonded to Silica Gel∗

Abstract

Abstract Cellulose was bonded chemically to 3-aminopropyl silica gel with diisocyanates and then allowed to react with a large excess of 3,5-dimethylphenyl- or 3,5-dichlorophenylisocyanate. Optical resolving power of these chiral stationary phases was compared with that of the cellulose triphenylcarbamate derivatives coated on silica gel.
