| titleOfInvention | Preparation method of coating-type polysaccharide chiral stationary phase |
| abstract | The invention relates to a preparation method of a chiral stationary phase. A preparation method of a coating-type polysaccharide chiral stationary phase is characterized in that the method comprises the following steps: 1) coating polysaccharides on a silica gel surface to obtain a polysaccharide-silica gel compound; 2) performing derivatization of the polysaccharide-silica gel compound by isocyanate or acyl chloride to obtain a derivatized polysaccharide-silica gel compound; 3) performing end blocking of the surface silanol groups of the derivatized polysaccharide-silica gel compound by silane to obtain the coating-type polysaccharide chiral stationary phase. The method can overcome the problem that some polysaccharide derivatives are difficult to be dissolved in common organic solventsand thus can not be coated, and the prepared stationary phase has very good chiral separation capability. |
