CHIRAL CHROMATOGRAPHIC DISCRIMINATION ABILITY OF A CELLULOSE 3,5-DIMETHYLPHENYLCARBAMATE 10-UNDECENOATE MIXED DERIVATIVE FIXED ON SEVERAL CHROMATOGRAPHIC MATRICES/

The properties as chiral selector in HPLC chiral stationary phases (CS Ps) of a cellulose derivative bearing simultaneously 3,5-dimethylpheny lamino carbonyl and 10-undecenoyl groups are described. This polysacch aride is reticulated (or bonded) on chromatographic supports such as s ilica gel, previously treated or not, graphite or alumina. The chiral stationary phases thus obtained are resistant to the usual solvents us ed in liquid chromatography and can be used on normal or reversed phas e conditions. The results obtained on the resolution of racemic compou nds with these stationary phases depend on the nature of the support. The best results were obtained with the chiral stationary phase in whi ch the cellulose derivative is bonded on allyl silica gel.
