Optical resolution of a range of racemic compounds was investigated using bis(aryl carbamate) derivatives of chitin coated onto microporous organosilane-modified silica. The influence on chiral discrimination of factors such as the carbamate/support weight ratio, the nature of polysaccharide, and the influence of the aryl group substituents was investigated. The bis(3,5-dimethylphenyl carbamate) derivative of a noncommerical chitin gave the best results.
