丁酸异戊酯制备

1.由异戊醇和正丁酸在浓硫酸或Twitchell试剂存在下加热酯化后分馏精制而得。

杂多钨酸催化法
将0.121mol异戊醇和0.1lmol丁酸、0.15g杂多钨酸、5mL苯和沸石加入100mL的烧瓶中，在122~132℃下回流反应1.5h即可得成品，酯化率可达97.8%。
硫酸催化法
先后将异戊醇、丁酸和硫酸加入反应釜，加热回流反应数小时。冷却后用10%的NaOH溶液中和，再水洗至中性，最后用无水氯化钙干燥后减压蒸馏得产品。

由异戊醇与丁酸酯化，经中和、洗涤、干燥制得。

精制方法：所含杂质除丁酸、异戊醇外，尚有戊醇、丁醇、己醇的丁酸酯类。精制时用碳酸氢钠和水洗涤后，无水硫酸钠或碳酸钾干燥、精馏。
