【摘要】 以固体超强酸S2 O2 - 8/TiO2 为催化剂合成了乙酸己酯 ,考察了催化剂制备条件对催化活性的影响以及酸醇摩尔比、催化剂用量、反应时间对酯化率的影响。最佳反应条件为 :酸醇摩尔比 0 2 0∶0 2 4 ,催化剂用量0 6g ,反应时间 2h ,带水剂苯 1 0ml ,反应温度 1 0 0℃～ 1 1 0℃ ,酯化率可达 96 %以上。更多还原

【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更多还原
