摘　　要：以全氟磺酸树脂膜为催化剂得到冰乙酸和异戊醇反应合成乙酸异戊酣适宜的反应条件。当n酸:n醇=1.2:1,催化剂用量(质量分数)为反应物总量的2%,反应温度为110℃,反应时间为1.5h的条件下,酯收率可达98.1%。该催化剂使用后无须任何处理可重复使用,是一种稳定性好的环境友好催化剂。The optimum reaction conditions of the synthesis of isoamyl acetate with Nafion NR50 resin membrane as catalyst were studied. The results showed that the yield was over 98.1 % when the molar ratio of acetic acid to isoamyl alcohol was 1.2:1, the amount of catalyst was 2 % of the total mass of reactants, temperature was 110℃ and reaction time was 1.5h.The catalyst could be used repeatedly for many times without distinct loss in activity.
