'''乙二醇单甲醚'''，结构式HOCH<sub>2</sub>CH<sub>2</sub>OCH<sub>3</sub>。

== 性质 ==
无色、具有令人愉快气味的透明液体。与水、[[乙醇]]、[[乙醚]]、[[丙酮]]、[[甘油]]、[[二甲基甲酰胺]]混溶。有毒，可引起巨红细胞性贫血，出现新生颗粒性白血球并引起中枢神经障碍。<ref name="zghg" />

== 制备 ==
[[甲醇]]与[[三氟化硼-乙醚络合物]]混合，再於40&nbsp;°C搅拌下缓慢通入[[环氧乙烷]]进行反应。反应后用碱中和，常压蒸馏除去多余甲醇，减压蒸出产物。
:<math>\ H_2C(O)CH_2+CH_3OH\rightarrow HOCH_2CH_2OCH_3</math>

== 用途 ==
用作油脂、合成树脂、醇溶性染料、[[硝基纤维素]]的溶剂，清漆和珐琅的快乾溶剂，涂层稀释剂，染料工业中的匀染剂和渗透剂，以及分析化学中硫酸盐、铁和[[二硫化碳]]的测定试剂等。
