| titleOfInvention | A kind of preparation method of Glucosamine Sulphate double salt |
| abstract | The present invention relates to a kind of Glucosamine Sulphate double salt and preparation method thereof, the X diffraction of double salt shows there is highest peak at 27.080 °, preparation method is dried to obtain Glucosamine the following steps are included: 1. chitins and alkali carbonate solution carry out deacetylation under microwave heating condition；2. glucosamine solution is made in obtained Glucosamine, excessive acidic sulphate solution is added into glucosamine solution and neutralizes and be allowed to sulphation, the ammonia of generation is removed using chlorine, and active carbon is added and carries out decoloring reaction, filters while hot；3. metal salt containing chlorine is added into the solution that step 2 obtains, heating carries out ion-exchange reactions, carries out back flow reaction；4. alcohol is added into the solution after step 3 reaction as precipitating reagent, sediment is obtained by filtration, sediment is subjected to freeze-drying and obtains Glucosamine Sulphate double salt fine work.Preparation method simple production process of the invention, low in cost, product purity is high, and quality reaches standards of pharmacopoeia, can be used for being mass produced. |
