采用微波辐射技术 ,以 Sn Cl4· 5 H2 O为催化剂催化合成了乙酸正丁酯。最佳反应条件 :醇酸配比为 1∶1.2 ,催化剂用量为 1.4g,微波功率为 45 0 W,微波辐射时间为 15 min,产率 95 %。实验结果表明适当的微波辐射可以加速乙酸正丁酯的合成反应 ,而且产率高 ,操作简便 ,腐蚀性小。 Microwave irradiation was used to synthesize n - butyl acetate catalyzed by SnCl4 · 5H2O. The optimal reaction conditions were as follows: alkyd ratio of 1: 1.2, catalyst dosage of 1.4 g, microwave power of 45 0 W, microwave irradiation time of 15 min, and yield of 95%. The experimental results show that proper microwave radiation accelerates the synthesis of n-butyl acetate, and the yield is high, the operation is simple and the corrosion is small.
