Improvement of the synthesis of vitamin E catalyzed by montmorillonite

Montmorillonite K 10 or montmorillonite K 10-supported metal salt as catalysts to synthesize VE (yield 21.0-64.4%) with 2,3,5-trimethylhydroquinone and isophytol. The catalysts can be reused.

Synthesis of D,L-α-tocopherol using strong solid acids as catalysts

The synthesis of D,L-α-tocopherol starting from trimethylhydroquinone and isophytol using a heterogeneous solid acid catalyst, e.g., Nafion NR 50, is described. Advantages of this new procedure are high yield and selectivity, facile recovery of the catalyst, no waste problems, and mild reaction conditions.
