Synthesis of d,l-α-Tocopherol Catalyzed by Heteropoly Acids

Department of Chemistry, Central South University of Technology, Changsha 410083

Received Date: 4 November 1998

d,l-α-lbcopherol(vitamin E) is found to be synthesized by condensing trimcthylhydroquinone with isophytol catalyzed by heteropoly acids(HPA) H₂PW₁₂O₄₀ and H₂PMo₁₂O₄₀ at room temperature. These HPA are efficient catalysts for the synthesis of d,l-α-Tocophcrol and can easily be separated from the reaction mixture and reused.
