中文摘要	The synthesis of D, L-alpha-tocopherol from trimethylhydroquinone and isophytol using the Bronsted acidic SO3H-functionalized ionic liquids as catalysts was explored. The catalytic activities of the SO3H-functionalized ionic liquids were dependent on their anions. The yield of D, L-alpha-tocopherol also depended on the solvent, which was the reaction medium. A yield of 94.3% was obtained using the SO3H-functionalized ionic liquid with [BF4-] anion as catalyst in propylene carbonate/heptane. The reaction mixture exhibited good biphasic behaviors, so that the produced D, L-alpha-tocopherol could be separated by decantation. The SO3H-functionalized ionic liquids could be reused after the removal of water.
