Abstract
SO42-/SnO2-Hangjin 2# solid acid catalyst was prepared by sol-gel method,and applied to synthesis terpinyl acetate from terpineol and acetic anhydride through esterification.The influences of preparative conditions of the catalyst on the reactive activity were investigated.The catalyst was characterized by FT-IR、TG-DTA、XRD and BET.The results revealed that the optimum preparative conditions of the catalyst were as followed: SnCl4 concentration 0.3 mol/L,sulfuric acid concentration 2.5 mol/L,calcination temperature 350 ℃.Under the conditions,conversion of terpineol could reach 99% and selectivity to terpinyl acetate could reach 90%.
