1,2-二乙氧基乙烷合成路线

1,2-二乙氧基乙烷上下游产品

1,2-二乙氧基乙烷上游产品

1,2-二乙氧基乙烷下游产品

1,2-二乙氧基乙烷制备

1.由环氧乙烷与乙醇反应而得。

精制方法：加无水氯化锡回流或通过活性氧化铝以除去过氧化物。微量水分可加金属钠蒸馏除去，再分馏精制。也可以在乙二醇二乙醚中加入200ml水和27ml浓盐酸，在氮气流下回流12小时，冷却后慢慢加入粒状氢氧化钾，并不断摇动，至氢氧化钾不再溶解时，倾出有机层。再重复操作一次。使用前加金属钠回流后蒸馏。

2.边搅拌边将金属钠分次少量加到乙二醇单乙醚中，生成醇钠，然后将醇钠溶液降温至50℃，再加入溴乙烷，控制加料速度，使之反应液温度逐渐上升至110℃

反应结束后，冷却，滤除溴化钠，最后，在0.1MPa下蒸馏，收集120.5～120.8℃馏分，即为成品。
