Abstract: Compared with vitamin E (VE), vitamin E succinate (VES) is stabler and has a wide use in medical and cosmetics fields. The reaction solution was prepared by vitamin E and succinic anhydride as resource, acetone as solvent, triethylamine as catalyst. The reaction solution was placed at 3FFC for about ten hours and the succinic anhydride can be cemented out from the mixture, the reclaiming can reach 82.6%. Then the distillation cut of triethylamine and acetone were got in the vacuum of 0.08MPa. The residue was dissolved in hexane. The solution precipitated and separated quickly, then it was filtrated and washed; the reclaiming of VES is 82% and purity of the product is 93%.

Key words: VE: vitamin E succinate, succinic anhydride: triethylamine, separation
