环己烷沸点

毒性：属低毒类。有刺激和麻醉作用。 
急性毒性：LD 5012705mg/kg(大鼠经口) 
刺激性：家兔经皮：1548mg(2天)，间歇，皮肤刺激。 
亚急性和慢性毒性：家兔分别吸入65g/m 3，6小时/天，2周；44g/m 3，6小时/天，2周；32g/m 3，6小时/天，5周，分别出现3/4，1/4，3/4死亡。表现有足爪节律性痉挛、麻醉、暂时轻瘫、流涎、结膜刺激等症状。 
致突变性：DNA损伤：大肠杆菌10µmol/L。 
危险特性：极易燃，其蒸气与空气可形成爆炸性混合物。遇明火、高热极易燃烧爆炸。与氧化剂接触发生强烈反应，甚至引起燃烧。在火场中，受热的容器有爆炸危险。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。

6.应急处理处置方法: 
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。也可以用不燃性分散剂制成的乳液刷洗，洗液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。 
废弃物处置方法：用焚烧法。 
二、防护措施 
呼吸系统防护：一般不需要特殊防护，高浓度接触时可佩戴自吸过滤式防毒面具(半面罩)。 
眼睛防护：空气中浓度超标时，戴安全防护眼镜。 
身体防护：穿防静电工作服。 
手防护：戴防苯耐油手套。 
其它：工作现场严禁吸烟。避免长期反复接触。 
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。 
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：喷水冷却容器，可能的话将容器从火场移至空旷处。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：泡沫、干粉、二氧化碳、砂土。用水灭火无效。
