乙二醇二甲醚
乙二醇二甲醚（C₄H10O₂）是一种无色透明液体，又称1,2-二甲氧基乙烷、二甲基溶纤剂、Glyme、monoglyme、dimethyl glycol、ethylene glycol dimethyl ether、dimethyl cellosolve和DME，是一种无色透明液体，具有乙醚气味。它溶于水、乙醇、乙醚、氯仿等溶剂。乙二醇二甲醚化学性质稳定，广泛应用于聚合物化学、电化学、硼化学工艺等领域，以及作为树脂、硝化纤维素等的溶剂。沸点高于乙醚和THF，常被用作那两种的替代品。此外，乙二醇二甲醚与双齿配体反应形成螯合物，可用于有机金属化学反应，如格林纳试剂、还原氢化反应、铃木反应和施蒂勒反应等。乙二醇二甲醚是最低能量、最稳定的构象，而非对位交叉式构象。
概况简介 编辑本段
乙二醇二甲醚(DME)是一种带有醚味的水白色中性液体，性质稳定，不易发生反应，能溶解各种树脂和纤维素，并能与水和许多醇，酮，酯等有机溶剂以任意比例混溶，其溶解能力可以通过水或某些溶剂作适当稀释来调节。DME是一种性能优良的非质子极性溶剂，除了用作气体吸收剂，萃取剂和脱漆剂外，还可以用于以下化学领域。用于电化学：由于DME的特殊结构，可替代水作非水溶液电解质溶剂，用于电化学设备，充电电池及有机化合物电解反应等。
比如：苯，四丁基溴化铵，DME的水溶液体系进行电解反应，可制得纯度为百分之九十六的1,4二羟基苯。制备硼化学： DME作为溶剂，可用于制得硼，硼氢化物，多硼氢化合物，多硼氢酸盐等多种硼衍生物。比如；三烷基硼化物和氢化铝钠在DME中反应，制得的硼氢化钠纯度高，颗粒大。制备有机金属化合物： DME是有机金属反应的重要试剂，可用于制备锑，硒，锡，钛，铼，铁，钌等有机金属化合物。用于高分子材料的聚合反应；用作清洗剂复配物；用于有机化合物及医药中间体的合成等。

一、泄漏应急处理
迅速撤离泄漏污染区人员至安全区，并进行隔离，严格限制出入。切断火源。建议应急处理人员戴自给正压式呼吸器，穿消防防护服。尽可能切断泄漏源，防止进入下水道、排洪沟等限制性空间。小量泄漏：用活性炭或其它惰性材料吸收。也可以用大量水冲洗，洗水稀释后放入废水系统。大量泄漏：构筑围堤或挖坑收容；用泡沫覆盖，降低蒸气灾害。用防爆泵转移至槽车或专用收集器内，回收或运至废物处理场所处置。
二、防护措施
呼吸系统防护：高浓度蒸气接触可佩戴过滤式防毒面具(半面罩)。
眼睛防护：一般不需要特殊防护，高浓度接触时可戴化学安全防护眼镜。
身体防护：穿防静电工作服。
手防护：戴乳白色胶手套。
其它：工作现场禁止吸烟、进食和饮水。工作毕，淋浴更衣。注意个人清洁卫生。
三、急救措施
皮肤接触：脱去被污染的衣着，用肥皂水和清水彻底冲洗皮肤。
吸入：迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难，给输氧。如呼吸停止，立即进行人工呼吸。就医。
食入：饮足量温水，催吐，就医。
灭火方法：尽可能将容器从火场移至空旷处。喷水保持火场容器冷却，直至灭火结束。处在火场中的容器若已变色或从安全泄压装置中产生声音，必须马上撤离。灭火剂：抗溶性泡沫、干粉、二氧化碳、砂土。
