| titleOfInvention | A kind of preparation method of Chitosan Sulfate |
| abstract | The present invention relates to the preparation method of a kind of Chitosan Sulfate, belong to technical field of medicine synthesis.In order to solve that prior art exists problem thickness and expansion easily occur, the preparation method of a kind of Chitosan Sulfate is provided, the method includes adding raw materials of chitosan and carries out reaction in the hydrochloric acid of 10wt%～30wt% and make formation chitosan hydrochlorate, filter, collect center casing polysaccharide HCl, solid；Chitosan hydrochlorate solid is added C 1 ～C 3 In alcoholic solvent, it is subsequently adding sulphuric acid and carries out reaction and make formation Chitosan Sulfate.The present invention has the problem not havinging thickness and volumetric expansion in accordance with the law, and product needs not move through pulverization process, it becomes possible to make product granularity keep 100% by more than 80 mesh, greatly simplified production technology, can significantly decrease production cost. |
