动物实验本品有麻醉作用及损害肾脏。对眼有刺激性。对皮肤刺激作用不明显,可经皮肤吸收。未见职业性危害。 皮肤接触:脱去污染的衣着,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。 燃烧性:可燃。引燃温度:190℃

爆炸下限[%(V/V)]:1.4 爆炸上限[%(V/V/)]:17.4

有害燃烧产物:无资料。

灭火剂:泡沫、干粉、二氧化碳、砂土。 急性毒性:大鼠经口LD50:5400mg/kg;小鼠经口LC5O:6000mg/kg

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。

侵入途径:吸入、食入、经皮吸收。

健康危害:口服引起恶心、呕吐、腹绞痛、虚弱、昏迷。具有刺激性。

刺激性:家兔经眼:50mg,中度刺激。家兔经皮开放性刺激试验:500mg,轻度刺激。 危险特性:易燃,遇明火、高热易引起燃烧爆炸。与氧化剂能发生强烈反应。接触空气或在光照条件下可生成具有潜在爆炸危险性的过氧化物。其蒸气比空气重,能在较低处扩散到相当远的地方,遇明火会引着回燃。

燃烧(分解)产物:一氧化碳、二氧化碳。

晚上好,二乙二醇丁醚是一种高沸点极性溶剂一般不会使人昏迷和眩晕,它有一种不愉快挥发气味通常只作为溶剂稀释某些树脂或者保湿,大量吸入气体时会和乙二醇丁醚有相似的急性肝肾损害,这两种醇醚在油墨涂料制造工业很常见俗称大防白和小防白。

不可以。

虽然城市里大多是使用天然气,但是农村地区还是用灌装的液化气,这种会比较方便一点,最近媒体曝光黑心气站为了赚钱往液化气里掺二甲醚,液化气里掺二甲醚有什么危害?怎么辨别一罐液化气是不是掺了二甲醚。

在2008年3月7日,国家质检总局发布了《关于气瓶充装有关问题的通知》,明确规定不得在民用液化石油气中掺入二甲醚后充入液化石油气钢瓶或在焊接气瓶中擅自加入不明化学添加剂。

天津大学教授姚春德介绍说,二甲醚也是一种可燃烧的气体,但燃烧的热值仅有液化气的三分之二,因二者可以互溶,给了不法商贩可乘之机。但二甲醚有一定的腐蚀性,掺入液化气后使得气罐泄漏的风险大大增加。二甲醚不同,它对橡胶有很强的腐蚀作用,一旦普通的液化气罐里掺入二甲醚后,二甲醚便会从内部开始腐蚀胶管,这种由内向外的腐蚀,很难被发现,时间久了胶管被腐蚀到一定程度,不少爆炸事故也由此发生。

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。

是。乙二醇又名“甘醇”、亚乙基二醇”,简称EG,化学式为(CH2OH)无色无臭、有甜味液体,是最简单的二元醇,。该液体是双氧水的稳定剂,二甘醇、二乙二醇单甲醚都属于双氧水的稳定剂。双氧水的主要药物成分为过氧化氢,主要适用于化脓性外耳道炎和中耳炎、文森口腔炎、齿龈脓漏、扁桃体炎及清洁伤口
