| 摘 要： | 以乙酸和正丁醇为原料,分别以浓硫酸、三氯化铁和固体超强酸SO42-/Fe2O3为催化剂合成乙酸正丁酯。利用正交设计法,通过极差分析,探讨了催化剂种类、醇酸摩尔配比和酯化时间及它们之间的交互作用对酯的收率的影响。实验结果表明较好的酯化条件是:n(醇):n(酸)为1:2;催化剂为固体超强酸SO42-/Fe2O3;酯化时间为2h。其酯的收率可达93.5%。

| Abstract: | Butyl acetate was synthesized by using acetic acid and n-butane as materials,sulfuric acid and ferric chloride and solid super acid as catalysts,respectively.In order to improve the conditions of synthesis,the effects of kinds of catalysts,mole ratio of alcohol and acid,reaction time were investigated by the variance analysis.The results of the experiment showed that the etherification ratio can be reached 93.5% when the mole ratio of alcohol and acid was 1:2;solid super acid SO42-/Fe2O3 as catalysts and the reaction time for 2 hours. |
