氯气为黄绿色有异臭和强刺激性的气体,在高压下液化为液氯,易溶于水和碱性溶液,也易溶于二硫化碳和四氯化碳等有机溶液。干燥氯气低温下不活泼,遇水可生成次氯酸和盐酸,次氯酸再分解为氯化氢和新生态氧,其损害作用主要由氯化氢和次氯酸所致。氯气在高温下与一氧化碳作用,生成高毒的光气。氯气能与可燃气体形成爆炸性混合物,液氯与许多有机物,如烃、醇、醚、氢气等发生爆炸性反应。氯气由电解食盐产生,
Chlorine is a yellow-green odor and strong irritant gas liquefaction to liquid chlorine under high pressure, soluble in water and alkaline solution, but also soluble in organic solvents such as carbon disulfide and carbon tetrachloride. Dry chlorine at low temperature is not active, water can generate hypochlorous acid and hydrochloric acid, hypochlorous acid and then break down into hydrogen chloride and new oxygen, the damage caused mainly by hydrogen chloride and hypochlorous acid. Chlorine and carbon monoxide at high temperatures, generating highly toxic phosgene. Chlorine and combustible gases can form explosive mixtures, liquid chlorine and many organic matter, such as hydrocarbons, alcohols, ethers, hydrogen and other explosive reaction. Chlorine is produced from electrolytic salt,
