补充资料：四氯乙烯
又称全氯乙烯。为乙烯中全部氢原子被氯取代而生成的化合物,分子式Cl2C匉CCl2。无色液体;熔点－19℃，沸点121℃,相对密度1.6227(20/4℃)；不溶于水，溶于乙醇、乙醚和苯等；气味像乙醚；不能燃烧。
四氯乙烯较为稳定，不易发生加成反应。它与乙醇钠作用时，氯原子可被乙氧基取代，生成二氯乙烯酮乙缩酮，再与乙醇加成，水解后可得二氯乙酸乙酯：
工业上四氯乙烯用1,1,2,2－四氯乙烷氧化脱氢或乙炔催化氯化的方法制取；也可用石灰乳处理五氯乙烷而制得：
四氯乙烯主要用作有机溶剂、干洗剂和金属去脂剂；曾用于驱除人体内的钩虫和姜片虫；高浓度时有麻醉作用，对皮肤有脱脂作用并能引起皮炎。
