二氯乙基醚制备

1.精制方法：用浓盐酸多次洗涤后减压蒸馏。

2.制法：

于装有搅拌器、温度计、回流冷凝器(连一导气管吸收氯化氢和二氧化硫)、滴液漏斗反应瓶中，加入β，β′-二羟基二乙醚(2)500g（4.71mol），冰水浴冷至0℃左右，慢慢滴加氯化亚砜1200g，控制反应液温度在20℃以下，约5h加完。加完后室温搅拌3h，放置过夜。慢慢加入吡啶50～60mL，回流反应3h，蒸出过量的氯化亚砜。冷后倒入冰水中，静置，分出有机层，用饱和碳酸钠水溶液洗涤，无水氯化钙干燥，过滤，减压蒸馏，收集55～65℃/1.0～1.2kPa的馏分，得β，β′-二氯二乙醚(1)538.4g,收率80%。

^3.制法：

于装有搅拌器、温度计、滴液漏斗、回流冷凝器（安装气体导管至SO2、HCl气体吸收瓶）的反应瓶中，加入β，β＇-二羟基二乙醚（2）500g，冰盐浴冷至0℃，搅拌下慢慢滴加氯化亚砜1.2kg，控制温度不超过20℃，约4h加完。而后室温反应3h。放置过夜，加入吡啶5g，回流反应3h。冷却后，慢慢倒入冰水中，充分搅拌。静置分层。分出有机层，用饱和碳酸钠溶液洗涤至中性。无水磷酸钙干燥，减压蒸馏，收集55～60℃/1.0～1.2kPa的馏分，得β，β＇-二氯二乙醚^①（1），收率80%。注：①也可由氯乙醇在硫酸存在下加热脱水来制备。
