2-乙基己醇是一种有机化合物,分子式为C8H18O,它是一种具有手性的支链

性质

[编辑]

无色有特殊气味液体。可燃。粘度:9.8 mPa·s(20°C)。 溶于约720倍的水,与氯仿等多数有机溶剂互溶。与水形成共沸混合物,其中水占20%,共沸点99.1°C。

制备

[编辑]

1、丙烯合成气羰基合成得到丁醛,后者两分子羟醛缩合得到2-乙基-2-己烯醛,最后加氢,得到2-乙基-1-己醇。



2、两分子乙醛羟醛加成为丁醇醛,失水得巴豆醛加氢正丁醛,然后两分子正丁醛缩合为2-乙基-2-己烯醛,最后加氢得2-乙基-1-己醇。

正丁醛缩合失水以及产物加氢的方程式与(1)中相同。

用途

[编辑]

用于制取鄰苯二甲酸二(2-乙基己基)酯对苯二甲酸二(2-乙基己基)酯、壬二酸二异辛酯和癸二酸二异辛酯等增塑剂。也用于合成抗氧化剂、润滑剂、消泡剂、溶剂,用于照相、纸张上浆、胶乳和织物印染等方面。
