| titleOfInvention | Purification method of vitamin E polyethylene glycol succinate |
| abstract | The invention discloses a purification method of vitamin E polyethylene glycol succinate, belonging to the technical field of purification. The method comprises the following steps: dissolving vitamin E polyethylene glycol succinate to be separated in an organic solvent, washing at least once by using saline water, adsorbing by using an adsorbent after washing, filtering after adsorption is finished, and evaporating the solvent to obtain the high-purity vitamin E polyethylene glycol succinate. The method purifies the vitamin E polyethylene glycol succinate crude product with simple process and low cost, has simple operation, does not need special equipment, can effectively remove polyethylene glycol and vitamin E succinate in the product, can remove more than 98 percent of polyethylene glycol and vitamin E succinate by the purification of the method, can improve the total content of monoester and diester in the product from 70-90 percent to more than 98 percent, and has the total ester yield of more than 96 percent. |
