苯(CeH_6)在工业上由焦炉气(煤气)和煤焦油的轻油部分中提取回收。苯是无色透明易挥发的液体。有强烈芳香气味。苯蒸气比空气重。不溶于水,溶于乙醇、乙醚、丙酮等有机溶剂。燃烧时发生光亮而带烟的火焰。蒸气与空气形成爆炸性混合物。苯在工业上用途很广,主要用作化工原料和有机溶剂,如合成苯的衍生物,制作香料、染料、塑料、农药、医药、炸药、橡
Benzene (CeH 6) is industrially extracted and recovered from the light oil fraction of coke oven gas (coal gas) and coal tar. Benzene is a colorless, transparent and volatile liquid. A strong aroma Benzene vapor is heavier than air. Do not dissolve in water, soluble in ethanol, ether, acetone and other organic solvents. Bright and smokey flame occurs when burning. Vapors and air form explosive mixtures. Benzene widely used in industry, mainly for chemical raw materials and organic solvents, such as the synthesis of benzene derivatives, the production of spices, dyes, plastics, pesticides, pharmaceuticals, explosives, rubber
