'''1,1,2,2-四溴乙烷'''，结构式CHBr<sub>2</sub>CHBr<sub>2</sub>，是[[四溴乙烷]]的两种[[同分异构体]]之一。

==性质==
白色或淡黄色有[[樟脑]]和[[三碘甲烷|碘仿]]气味的易燃液体。不溶于水，与[[乙醇]]、[[乙醚]]、[[三氯甲烷|氯仿]]、[[乙酸|冰醋酸]]和[[苯胺]]混溶。受光照和加热时发生分解并使颜色发黄。加热至190°C时分解产生剧毒的[[碳酰溴]]蒸气。

==毒性==
有毒，吸入后可对人体的肝脏造成严重损害，还可引起呼吸困难、运动失调、肺出血而死。<ref name="zghg">中国化工产品大全 上卷，Da034 1,1,2,2-四溴乙烷，页465</ref><ref>[http://www.guidechem.com/dictionary/79-27-6.html 1,1,2,2-四溴乙烷 字典-Guidechem.com{{en}}]</ref>

==制备==
由已净化的[[乙炔]]与[[溴]]在水存在和加压下发生[[加成反应|加成]]得到。反应后用稀碱液洗涤，并除上层碱液，用水洗，得成品。
:<math>\ CH\! \equiv \!CH+2Br_2 \ \xrightarrow [1.9613\!-\!4.9033kPa]{<50^oC} \ CHBr_2CHBr_2</math>

==用途==
用作有机合成（如用于合成[[季铵盐]]）、医药和染料中间体。也用于制取致冷剂、熏蒸消毒剂、灭火剂、化学纤维助催化剂、[[涤纶]]氧化工序引发剂等。
