| titleOfInvention | Preparation and application of positive charge type polysaccharide derivative chiral stationary phase |
| abstract | The invention provides a preparation method of a positive charge type polysaccharide derivative chiral stationary phase and separating for alkaline chiral compounds. The method specifically comprises the steps that polysaccharide and polysaccharide derivatization reagent react with chemical reagents containing secondary amine, tertiary amine or quaternary amine and other radical groups in a reaction container containing an organic solvent; methyl alcohol is used for washing solid, and the solid is dried and used later; polysaccharide derivatives containing positive charges is arranged on a common chromatography substrate such as silica gel in a coated mode, and the positive charge type polysaccharide derivative chiral stationary phase can be prepared after drying is finished. The method has the advantages that preparation is simple, quick and good in repeatability, and difference derivatization reagents can be selected as required to prepare positive charge type chiral stationary phases with different chiral recognition capabilities. The prepared positive charge type polysaccharide derivative chiral stationary phase is mainly used for separating of the alkaline chiral compounds, and quick separating of the alkaline chiral compounds can be achieved under the neutral and acid mobile phase condition. |
