求翻譯:最簡單的芳香烴。分子式C6H6。為有機化學工業的基本原料之一。無色、易燃、有特殊氣味的液體。熔點5.5℃,沸點80.1℃,相對密度0.8765(20/4℃)。在水中的溶解度很小,能與乙醇、乙醚、二硫化碳等有機溶劑混溶。能與水生成恒沸混合物,沸點為69.25℃,含苯 91.2%。因此,在有水生成的反應中常加苯蒸餾,以將水帶出。苯在燃燒時產生濃煙。是什么意思?![]() ![]() 最簡單的芳香烴。分子式C6H6。為有機化學工業的基本原料之一。無色、易燃、有特殊氣味的液體。熔點5.5℃,沸點80.1℃,相對密度0.8765(20/4℃)。在水中的溶解度很小,能與乙醇、乙醚、二硫化碳等有機溶劑混溶。能與水生成恒沸混合物,沸點為69.25℃,含苯 91.2%。因此,在有水生成的反應中常加苯蒸餾,以將水帶出。苯在燃燒時產生濃煙。
