苯乙烯 Styrene
（重定向自Vinyl benzene）
苯乙烯也被称为乙烯基苯，是用苯取代乙烯的一个氢原子形成的有机化合物。室温下，苯乙烯是一种具有甜味的粘稠易挥发液体，但苯乙烯浓度过高时，气味就会变得令人不愉快。苯乙烯中，乙烯基的电子与苯环共轭。苯乙烯不溶于水，溶于乙醇、乙醚中，暴露于空气中逐渐发生聚合及氧化。工业上是合成树脂、离子交换树脂及合成橡胶等的重要单体。于2010年，苯乙烯被生产了约2500万吨（550亿磅）。

Styrene, also known as ethenylbenzene, vinylbenzene, and phenylethene, is an organic compound with the chemical formula C6H5CH=CH2. This derivative of benzene is a colorless oily liquid that evaporates easily and has a sweet smell, although high concentrations have a less pleasant odor. Styrene is the precursor to polystyrene and several copolymers. Approximately 25 million tonnes (55 billion pounds) of styrene were produced in 2010.
