Efficient immobilization of cellulose phenylcarbamate bearing alkoxysilyl group onto silica gel by intermolecular polycondensation and its chiral recognition
Cellulose 3,5-dimethylphenylcarbamate bearing a small amount of 3-(triethoxysilyl)propyl residues was synthesized and effectively immobilized onto silica gel support for high-performance liquid chromatography by the polycondensation of triethoxysilyl groups. The immobilized chiral packing material (CPM) showed high chiral recognition as well as the conventional CPM prepared by coating the derivative onto silica gel, and can be used with a variety of eluents.
