丁酸丁酯制备

1.由丁酸与丁醇酯化而得。将丁酸、丁醇及少量硫酸加入反应锅，加热回流脱水约4-5h，再经碱液中和、洗涤，减压分馏，收集112℃（14.6kPa）馏分即得成品。

2.由丁酸与丁醇在硫酸催化下酯化，经洗涤、干燥、蒸馏制得。

精制方法：含有游离的丁酸和丁醇等杂质。若以发酵法生产的丁醇为原料，尚含有异丁醇、戊醇和己醇的丁酸酯。精制时用碳酸氢钠和水洗涤，无水硫酸铜或碳酸钠干燥后精馏。

3.由正丁醇的蒸气于400℃通过二氧化锰或氧化锌催化剂，便可生成丁酸丁酯。

4.制法：

于装有搅拌器、回流冷凝器的反应瓶中，加入正丁醛（2）50mL，含2.5g异丙醇铝的四氯化碳溶液5.0mL，反应放热，温度迅速上升至沸腾。反应结束后，依次用稀盐酸。水洗涤，无水硫酸镁干燥，分馏，收集164～166℃的馏分，得化合物（1）^①，收率60%。注：①若反应控制在20℃以下进行，丁酸丁酯的收率可达94%。当用叔丁醇铝作催化剂并低温反应时，收率为90%。
