Method of preparing vitamin E acetate
2016
The invention provides a method of preparing vitamin E acetate. The method includes the steps of: feeding hydrogen halide gas as a catalyst, supporting a metal halide and elementary metal on a molecular sieve to obtain a cocatalyst and a stabilizing agent, and performing a reaction to 2,3,5-trimethylhydroquinone diester (TMHQ-DA) and iso-phytol (IPL) to produce the vitamin E acetate (VEA). The method has high catalyst activity and has low corrosion on equipment, wherein the raw material is converted into the vitamin E acetate directly through one step. The product has good stability and the method is easy to carry out in industrial enlarged production.
