补充资料:丙烷
丙烷 propane 一种气体烷烃。分子式 CH3CH2CH3 。无色无臭的易燃气体 。熔点-189.7 ℃ ,沸点- 42.1℃ ,相对密度 0.5853(-45/4℃)。不溶于水 ,但在低温下容易与水生成固态水合物,引起天然气管道的堵塞。丙烷在较高温度下与过量氯气作用,生成四氯化碳和四氯乙烯 Cl2C=CCl2 ;在气相与硝酸作用,生成1-硝基丙烷 CH3CH2CH2NO2、2-硝基丙烷 (CH3)2CHNO2、硝基乙烷CH3CH2NO2和硝基甲烷CH3NO2的混合物。上丙烷可从油田气和裂化气中分离得到。可作生产乙烯和丙烯的原料或炼油工业中的溶剂;丙烷、丁烷和少量乙烷的混合物液化后可用作民用燃料,即液化石油气。 |
