乙苯 Ethylbenzene
（重定向自Phenylethane）
乙苯【拼音：yǐ běn；英文：Ethylbenzene】是一个芳香族的有机化合物，主要用途是在石油化学工业作为生产苯乙烯的中间体，所制成的苯乙烯一般被用来制备常用的塑料制品——聚苯乙烯。尽管在原油里存在少量的乙苯，但大批量生产仍然是靠在酸催化下苯与乙烯反应：
- C6H6 + C2H4 → C6H5CH2CH3
乙苯经过催化脱氢，生成氢气和聚苯乙烯：
乙苯也存在于某些颜料中。

Ethylbenzene is an organic compound with the formula C6H5CH2CH3. It is a highly flammable, colorless liquid with an odor similar to that of gasoline. This monocyclic aromatic hydrocarbon is important in the petrochemical industry as an intermediate in the production of styrene, the precursor to polystyrene, a common plastic material. In 2012, more than 99% of ethylbenzene produced was consumed in the production of styrene. Ethylbenzene is also used to make other chemicals, in fuel, and as a solvent in inks, rubber adhesives, varnishes, and paints. Ethylbenzene exposure can be determined by testing for the breakdown products in urine.
