  储存注意事项 储存于阴凉、通风的库房。远离火种、热源。库温不超过32℃，相对湿度不超过80%。包装要求密封，不可与空气接触。应与氧化剂、还原剂、碱类、金属粉末、食用化学品分开存放，切忌混储。不宜大量储存或久存。配备相应品种和数量的消防器材。储区应备有泄漏应急处理设备和合适的收容材料。

• 稳定性:

  1.化学性质：不含稳定剂的三氯乙烯逐渐在空气中被氧化，生成光气，一氧化碳和氯化氢。也有可能生成少量二聚物（六氯丁烯）。反应按游离基历程进行，光照和加热明显地促进反应进行。有水分存在时，二氯乙酰氯分解成二氯代乙酸和氯化氢。分解生成的酸性物质腐蚀金属。因此，通常工业所用的三氯乙烯需加入微量的稳定剂如酚类（对苯二酚）、胺类或醇类等。添加稳定剂的三氯乙烯在空气、水分和光存在下，即使加热至130℃与一般工业用金属材料也不作用。

  2.三氯乙烯蒸气加热至700℃以上，分解生成二氯乙烯、四氯乙烯、四氯化碳、氯仿以及氯甲烷的混合物。三氯乙烯蒸气与空气一起受强烈时，完全氧化生成二氧化碳、氯化氢、一氧化碳和光气等。在有铜盐存在时，三氯乙烯在加压下加热175℃，与碱金属或碱土金属的氢氧化物水溶液或悬浊液反应，生成羟基乙酸盐。冷时与盐酸及硝酸不反应，加热时与浓硝酸激烈反应而完全分解，控制反应条件可得到三氯硝基甲烷和一氯二硝基甲烷。在三氯化铝催化作用下，30~50℃与氯化氢反应，生成1,1,1,2-四氯乙烷。在苛性碱存在下易发生脱氯化氢反应生成二氯乙炔，二氯乙炔在空气中自燃并爆炸分解。碳酸钠及液态氨在通常条件下与三氯乙烯不反应。金属铝，特别是粉末状的金属铝，能促使不含稳定剂的三氯乙烯发生分解，生成氯化氢的同时，发生强烈的爆炸分解或炭化。反应先生成三氯化铝，三氯化铝作为Friedel Crafts催化剂促使三氯乙烯发生缩合反应，生成五氯丁二烯，进一步缩合成树脂、焦油。在三氯化铝存在下，三氯乙烯与氯仿反应，生成1,1,1,2,3,3-六氯丙烷。与四氯化碳反应生成1,1,1,2,3,3,3-七氯丙烷。在过氧化物，例如过氧化苯甲酰存在下，加压加热至150~200℃，得到三氯乙烯的二聚物和三聚物。在三氯化铁催化下，易氯化生成五氯乙烷和六氯乙烷。

制备

1.乙炔法　此法以电石发生的乙炔和氯气为原料、四氯化碳为稀释剂、三氯化铁为催化剂液相合成1,1,2,2-四氯乙烷，再加石灰乳脱氯化氢，得粗三氯乙烯，经粗馏、精馏，即得产品。因乙炔价格昂贵，大多转用乙烯法。

2.乙烯直接氯化法　经直接氯化得四氯乙烷和五氯乙烷的混合物，通过对其进行气相裂解制取三氯乙烯和四氯乙烯。其主要反应式如下：

3.乙烯氧氯化法　此法以乙烯、氧气（或空气）、氯气为原料，经催化氯化氧化得三氯乙烯产品，同时还可得四氯乙烯。其主要反应式如下：
