1.能与乙醇、乙醚、有机氯化物等一般有机溶剂混溶。能溶解油脂、蜡、天然树脂、橡胶、乙基纤维素和乙烯树脂等。20℃时在水中溶解度为0.436%;水在1,1,2-三氯乙烷中溶解度为0.05%。干燥的1,1,2-三氯乙烷对金属腐蚀性不强。和潮湿的空气接触,特别在光照下,释放出腐蚀性很强的氯化氢。液体的1,1,2-三氯乙烷的脱脂作用强,应避免与皮肤接触。

2.通常状态下性质稳定。没有空气和水存在时,加热至110℃也不发生明显的分解,但在其沸点与水接触时发生水解。与氢氧化钠溶液或氢氧化钙悬浮液一起加热,生成1,1-二氯乙烯,高温气相热裂也发生脱氯化氢反应。在三氯化铝存在下,70~80℃与氯反应生成1,1,2,2-四氯乙烷。

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,穿防毒服。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:用砂土或其它不燃材料吸附或吸收。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。废料同其它燃料混合后焚烧,燃烧要充分,防止生成光气。焚烧炉排气中的卤化氢通过酸洗涤器除去。
二、防护措施
呼吸系统防护:空气中浓度超标时,应该佩戴直接式防毒面具(半面罩)。紧急事态抢救或撤离时,佩戴空气呼吸器。
眼睛防护:戴安全防护眼镜。
身体防护:穿防毒物渗透工作服。
手防护:戴防化学品手套。
其它:工作现场禁止吸烟、进食和饮水。工作毕,沐浴更衣。单独存放被毒物污染的衣服,洗后备用。注意个人清洁卫生。
三、急救措施
