摘　　要：合成了甲烷磺酸铜 ,研究了其催化丁酸与异戊醇的酯化反应。反应条件为醇酸摩尔比 1 2∶1 0 ,催化剂用量 0 5 % (以酸的摩尔数计 ) ,反应时间 2 5h ,不加带水剂 ,回流反应温度在 130～ 135℃条件下 ,酯化率可达 95 8%。反应后甲烷磺酸铜经过简单的相分离就可重复使用 ,无需再生 ,兼有均相与多相催化剂的优点。Copper methanesulfonate was synthesized and used as a catalyst in the esterification of n-butyric acid with isoamyl alcohol. The results showed that at the condition of 1.2∶1 molar ratio of isoamyl alcohol to n-butyric acid, 0.5% catalyst(molar percent of n-butyric acid), 2.5 h, no water-carrying agent, at reflux temperature, the esterification degree achieved 95.8%. Copper methanesulfonate can be reused by simple phase-separation, no need of regeneration. It has merits of both homogeneous and heterogeneous catalyst. The catalytic activities of different Lewis acids were compared with it.
