| titleOfInvention | A kind of chitosan Bispyridinium salts and its preparation method and application |
| abstract | The present invention relates to household chemicals field and pharmaceuticals industry, is especially a kind of preparation method and application of Chitosan double quaternary ammonium salt derivative.Chitosan double quaternary ammonium salt derivative is qcts2Py, qcts3Py or qcts4Py shown in formula (1), (2) or (3)ï¼›Using chitosan as raw material, corresponding schiff bases are synthetically generated with the corresponding pyridine aldehydes of excess, then the chitosan of N substitutions is obtained by sodium borohydride reduction, then obtain bi-quaternary ammonium salt chitosan derivatives with iodomethane reaction again.Shown bi-quaternary ammonium salt derivative has good antioxidation activity compared with chitosan raw material.The present invention has synthesized Chitosan double quaternary ammonium salt derivative by effective synthesizing mean, and water-soluble preferable, and antioxidation activity significantly improves, and enhances the bioactivity of chitosan, expands the application of chitosan, can be used for the fields such as daily use chemicals and pharmaceuticals industry. |
