乙烯基正丁醚上游产品

乙烯基正丁醚下游产品

乙烯基正丁醚制备

1、乙炔法由乙炔与丁醇反应而得。此法所需设备少，选择性高。

2、乙醛法由乙醛与正丁醇反应而得。这种由缩醛裂解的方法也是乙烯基醚通用的工艺。另一种较新的方法是由醇；乙烯和氧在氯化钯-氯化铜催化剂存在下反应，也可以获得乙烯基醚。

3.制法：

于装有搅拌器、分馏装置的反应瓶中，加入醋酸汞5g(0.016mol),无水乙醇50g(1.08mol)，正丁基乙烯基醚（2）100g(1mol),接受瓶和冷凝器均充分冷却。加热回流，控制分馏柱馏出温度在36～37℃，共蒸出71g乙基乙烯基醚（1）。收率98%。蒸完后，反应瓶中加入水，共沸蒸馏，沸点97℃，最后得到正丁醇71.2g。
