| Abstract: | Several kinds of SO 2- 4/M xO y solid superacids were used to catalyze the synthesis of terpinyl acetate. Four kinds of them, SO 2- 4/TiO 2, SO 2- 4/ZrO 2, SO 2- 4/SnO 2 and SO 2- 4/Fe 2O 3 have high catalytic activities. The effects of reaction temperature, molar ratio, amount of SO 2- 4/TiO 2 catalyst and reaction times on selectivity of terpinyl acetate were studied. The main courses for the decrease of catalytic activity of SO 2- 4/TiO 2 were investigated. |
