| titleOfInvention | A kind of method for removing glycidyl ester and 3-chloropropanediol and ester thereof from natural vitamin E and obtained product |
| abstract | The invention relates to a method for removing natural vitamin E containing glycidyl ester, 3-chloropropanediol and their esters and a high-purity vitamin E product obtained by the method. The removal method includes the steps of activated carbon acid treatment, activated carbon chlorination, activated carbon amination, adsorption and separation, and the like. The technological process of the invention is simple and easy to implement, does not cause secondary pollution to the natural vitamin E product, and compared with the natural vitamin E raw materials used, the glycidyl ester content and 3-chloropropanediol of the high-purity vitamin E product obtained by the method of the invention The total content of 3-chloropropanediol and 3-chloropropanediol is reduced by more than 85% and more than 88% respectively. |
