摘　　要： 以异戊酸和氯化苄为原料,用732型强酸性阳离子树脂作催化剂发生酯化反应合成香料异戊酸苄酯。研究了催化用量、氯化苄与异戊酸的摩尔比、反应时间及反应温度对产率的影响;并对产物进行了分析。同时,对催化剂的重复使用性能进行了研究,研究表明,催化剂在重复使用5次后,产率基本不变,说明催化剂具有良好的重复使用性能。 The flavor benzyl carboxylate was synthesized with isovaleric acid and benzyl chloride as materials by 732# strongly acidic cationic exchange resin as catalyst. Many influence factors of reaction were studied, such as dosage of catalyst, molar ratio of benzyl chloride and isovaleric acid, reaction time and reaction temperature. And then, the reaction product was analyzed. At the same time, the reusability of catalyst was discussed, which showed the yield much would stay the same after the catalyst was reused 5 times. The results indicated that catalyst had good reusability.
