'''乙二醇单丁醚'''，分子式[[C6H14O2|C<sub>6</sub>H<sub>14</sub>O<sub>2</sub>]]，俗稱'''化白水'''。

== 性质 ==
无色、具中等程度[[醚]]气味的液体。易燃，低毒。溶于约20倍的水，溶于[[乙醇]]、[[乙醚]]、[[矿物油]]等多数有机溶剂。与[[石油烃]]具有很高的稀释比。

== 制备 ==
[[丁醇]]与[[三氟化硼-乙醚络合物]]混合，再於25～30&nbsp;°C通入[[环氧乙烷]]并升温至80&nbsp;°C进行反应。反应后回收多余丁醇、用碱中和、蒸馏、分馏，得乙二醇单丁醚成品。

== 用途 ==
用作喷漆、清漆、快乾漆、[[硝酸纤维素]]、搪瓷和脱漆剂等的溶剂、农药分散剂、有机合成原料、纤维润湿剂、树脂增塑剂，以及铁和钼的分析试剂等。
