摘要:
The present invention relates to liquid chromatographic chiral stationary phases (CSPs) and their preparation. The CSPs are based on carbamate-derivatized polysaccharides that are covalently bound onto inorganic oxide carriers via unique linkage chemistry. The present invention also relates to methods of obtaining the said linkages, which include derivatizing and functionalizing the polysaccharides, and also chemically bonding the functionalized carbamate-derivatized polysaccharides onto inorganic oxide carriers. The polysaccharide derivatives so obtained can be used as materials for the liquid chromatographic chiral separation of enantiomers. The preferred inorganic oxides are silica, zirconium oxide, and aluminum oxide. Cellulose and amylose are the preferred chiral polysaccharides.
