Process to produce α-tocopherol-acetate |
| abstract |
Process for the production of alpha-tocopherol acetate in a recycling process by condensation of trimethylhydroquinone diesters and isophytol in the presence of a catalyst system consisting of a zinc halide and of an aqueous protonic acid and optionally of an elemental metal in a polar solvent/water mixture which is extractable or miscible with water and subsequent recycling of the catalyst system. |
