The synthesis of benzyl acetate by sodium acetate and benzyl chloride was investigated in various 1,3-dialkylimidazolium and alkylpyridium ionic liquids. 1-Alkyl-3-methylimidazolium tetrafluoroborate ([C_nMIm][BF_4]) ionic liquids were found to be an effective solvent and catalyst for the reaction. When the reaction was performed at 60 ℃, the molten sodium acetate was miscible with 1- ethyl-3-methylimidazolium tetrafluoroborate ionic liquid but the product benzyl acetate was not. Therefore, the products could be conveniently separated by decantation. The benzyl acetate yield was as high as 90% with >99% purity. The ionic liquid could be reused for several times and did not lose the catalytic activity.
