TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The zinc halide is zinc chloride and/or zinc bromide. The hydrogen halide is dilute hydrochloric acid and/or hydrobromic acid.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method comprises: (a) adding a reaction solvent of 2,3,5-trimethylhydroquinone to a catalyst composed of a linear organic amine, zinc halide and hydrogen halide composition, under nitrogen atmosphere, stirring the reaction mixture and heating to the boiling point of the reaction solvent, maintaining the temperature of the isophytol for 2-2.5 hours, adding isophytol dropwise uniformly to the reaction mixture for 1-1.5 hours; (b) washing the reaction mixture with water, washing the solution by extraction, separating the solution by an oil-water separator, recycling the aqueous phase, and removing the organic phase solvent by distillation; (c) after removal of the organic phase solvent, adding acetic anhydride, under nitrogen, at 140 degrees C for esterification for 3 hours; and (d) recovering the unreacted acetic anhydride, washing with water and distilling under atmospheric pressure at 140 degrees C, to obtain vitamin E acetate crude product at bottom. In the step (b), adding catalyst into the reaction solvent and simultaneously drop-wisely adding isophytol, and recovering water using oil-water separator. In the step (a): the reaction solvent is a two phase system consisting of alkanes and water, and the alkane and 2,3,5-trimethylhydroquinone quinone present at a mass ratio of 2:1; the molar ratio of 2,3,5-trimethylhydroquinone and isophytol is 1:1-1.2; the molar ratio of the zinc halide and 2,3,5-trimethyl-hydroquinone is 0.7-0.8:1; and the mass ratio of linear, straight-chain organic amine, zinc halide and hydrogen halide is 1-2:70-75:1-3. Preferred Components: The organic amine is at lease one n-hexylamine, n-heptylamine, n-octylamine, n-nonylamine, n-quinamine, n-undecylamine, n-decylamine, n-tridecylamine or n-tetradecylamine.
