乙二醇二乙醚简介，有什么功效

到底是单甲醚，还是单乙醚，还是甲乙醚呢？

呵呵。不过上述三个物质的毒性类似，均与二乙二醇的毒性直接相关。

二乙二醇可以被人体吸收，并在体内降解为2个乙二醇，从而走乙二醇分解吸收的路线。

乙二醇在体内，对人的肝脏、肾脏功能损害严重。属于有毒物质。

所以你问的问题也是有毒的。但是从毒理学角度，它仅对人体有较大毒害，对一般实验用的小白鼠、家兔等毒性表现不明显。

我们为什么要使用工业防护涂料？四个字“保护作用”。钢材使用工业防护涂料可以防止被锈蚀，木材使用工业防护涂料可以防止腐朽，混凝土使用工业防护涂料可以防止被碳化。所以不同种类的防护涂料可以有效的保护被施用对象，延长其服役寿命。环保一直都是我们时代的主题，而近些年来，工业防护涂料有毒有害物质越来越被人们所重视。涂料的工艺生产决定其可能会产生一些VOC、重金属等等对人体有危害的成分，有毒有害物质也就成为工业防护涂料必不可少的检测项目。今天我们就跟大家好好介绍一下相关涂料检测的规定。

一、工业防护涂料中有害物质检测标准

GB 30981-2020《工业防护涂料中有害物质限量》是国家在今年3月份刚颁布的强制执行标准，并且规定将在12月1号正式实施。GB 30981-2020的前身是 GB 30981-2014《建筑钢结构防腐涂料中有害物质限量》。GB 30981-2020是对GB 30981-2014版本的延伸，检测范围也不在局限在钢结构防腐涂料，除了腻子以外，GB 30981-2020适用各种金属、塑料、橡胶、混凝土、机械设备、电子电器等等工业防护涂料，当然船舶涂料、航空涂料、航天涂料、核电涂料、军事设备及设施用涂料，这类涂料不适用该标准。

二、工业防护涂料中有害物质检测范围

农业机械防护涂料、港口机械防护涂料、化工机械防护涂料、建筑物防护涂料、构筑物防护涂料、集装箱防护涂料、包装防护涂料、电子电器防护涂料、型材防护涂料、预涂卷材用防护涂料、车间底漆、水性涂料、溶剂型涂料、无溶剂涂料、辐射固化涂料、粉末涂料、绝缘涂料、耐指纹涂料、标志漆、弹性体用氟硅涂料、聚四氟乙烯类涂料、电镀银效果漆等等的有毒有害物质检测

有乙二醇，结构简式是HOCH2CH2OH。

乙二醇氧化可以得到乙二醛OHC-CHO，再氧化得到乙二酸。

没有乙二醚，但是有二乙醚，实际上就是乙醚CH3CH2-O-CH2CH3。

乙醚是乙醇分子间脱水的产物。

乙二醇二甲醚*用 途

1.用作硝酸纤维素、树脂等的溶剂以及制备碱金属氧化物、硼烷时的溶剂。萘、联苯、三联苯、蒽等芳香烃在乙二醇二甲醚中与钠生成络合物。钠-萘络合物在聚四氟乙烯等含氟树脂黏合时用于表面处理。钠-联苯络合物用于汽油中的卤素测定。还可用于从稀乙酸水溶液中回收乙酸。也用于脱漆剂、稀释剂及增加润滑油的黏度等。

2.用作溶剂。用于电化学分析。

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。

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。 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。

眼睛接触：提起眼睑，用流动清水或生理盐水冲洗。就医。

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。

国标编号 32093 CAS号 110-71-4 中文名称 1，2-二甲氧基乙烷 英文名称 ethylene glycol dimethyl ether；1,2-dimethoxyethane 别 名 乙二醇二甲醚；二甲基溶纤剂 分子式 C4H10O2；CH3OCH2CH2OCH3 外观与性状 无色液体，略有醚味 分子量 90.12 蒸汽压 6.40kPa/20℃ 闪点：1℃/开杯 熔 点 -69℃ 沸点：83℃ 溶解性 溶于水、烃类 密 度 相对密度(水=1)0.87； 相对密度(空气=1)3.11 稳定性 稳定 危险标记 7(中闪点易燃液体) 主要用途 用作溶剂、医药抽提剂、有机合成中间体的主要成分 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。

不溶于。乙二醇二甲醚，又名1，2二甲氧基乙烷，是一种有机化合物，不溶于乙酸，乙酸又称醋酸，广泛存在于自然界，它是一种有机化合物，是典型的脂肪酸。被公认为食醋内酸味及刺激性气味的来源。
