Abstract
Hexyl acetate was synthesized by the new type solid superacid S 2O 2- 8 /TiO 2. The effects of preparation conditions of catalyst on catalytic activity and the effects of acid/alcohol molar ratio,amount of catalyst S 2O 2- 8 /TiO 2,and reaction time on the esterification conversion were studied.The optimum condition is :acid/alcohol molar ratio 0.20 ∶ 0.24 ,the amount of catalyst 0.6 g ,reaction time 2 h,the amount of dehydrater benzne 10 ml,reaction temperaure 100 ℃～110 ℃?The esterification conversion was over 96% under the optimum coditions
