| titleOfInvention | A kind of preparation method of phosphorated laminarin |
| abstract | The invention discloses a kind of preparation methods of phosphorated laminarin.Steps are as follows：（1）Laminarin is weighed at room temperature to mix with hydroxy ethylene diphosphonic acid di-potassium, adds urea；Three is heated to reaction 5-8h after mixing, obtains mixture；（2）By step（1）Distilled water is added in the obtained mixture, and is heated to 40-60 DEG C, using concentration, alcohol steep obtains the phosphorated product of laminarin after separation is dry.The present invention uses hydroxy ethylene diphosphonic acid di-potassium as organic phospho acid acidizing reagent, obtains the phosphorated laminarin of the base of function containing organic phospho acid by rare earth method, can effectively improve the phosphate content in laminarin derivative, to improve its activity.The present invention obtains hydroxy ethylene diphosphonic acid laminarin, and related synthesis preparation method is simple and easy to do, low in cost, convenient for industrialization and Technique Popularizing, can promote the use of in fields such as food additives, functional health care food and drugs. |
