密度：

1.435

熔点：

-37ºC

沸点：

110-115ºC

存储条件/存储方法：

库房通风低温干燥,与食品添加剂分开存放

稳定性相关：

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。
