百科

光气，又称碳酰氯，化学式为COCl2，是一种重要的有机中间体，是非常活泼的亲电试剂。高毒，不燃，化学反应活性较高，遇水后有强烈腐蚀性。微溶于水，溶于芳烃、苯、四氯化碳、氯仿、乙酸等多数有机溶剂。由一氧化碳和氯气的混合物通过活性炭制得。光气常温下为无色气体，有腐草味，低温时为黄绿色液体，化学性质不稳定，遇水迅速水解，生成氯化氢。是氯塑料高温热解产物之一。用作有机合成、农药、药物、染料及其他化工制品的中间体。脂肪族氯烃类（如氯仿、三氯乙烯等）燃烧时可产生光气。环境中的光气主要来自染料、农药、制药等生产工艺。吸入光气会损害呼吸道，导致化学性支气管炎、肺炎、肺水肿。当吸入较高浓度光气时，即可引起严重中毒，甚至死亡。

释义

Chemistry a colourless poisonous gas made by the reaction of chlorine and carbon dioxide. It was used as a poison gas, notably in the First World War.
