补充资料:氯甲烷
氯甲烷 chloromethane 甲烷分子中一个氢原子被氯取代而生成的化合物。分子式CH3Cl。又称甲基氯。无色易液化气体。熔点-97.1℃,沸点-24.2℃,相对密度0.9159(20/4℃)。微溶于水,易溶于乙醚、苯等。有可燃性,与空气能形成爆炸性混合物,爆炸极限8.1%~17.2%(体积)。氯甲烷在60℃以上水解时生成甲醇。工业上,氯甲烷是在光照或高温条件下,由天然气与氯气反应制得。由于氯化反应是按自由基机理进行的,反应不能停止在一氯阶段,而是生成氯甲烷、二氯甲烷、氯仿和四氯化碳的混合产物,适当控制条件和氯气用量,可使其中某一组分为主要产物,再通过精馏得到纯净产品。由于氯甲烷的沸点很低,与其他产物沸点差距较大,较易分离精制。氯甲烷曾用作麻醉剂和制冷剂,由于具有毒性和可燃性,已不再使用。主要用作生产各种有机硅树脂的原料。氯甲烷具有甜的醚香味和迟效性,中毒者初期感觉不到,因此慢性中毒很多。 |
