'''Ethylbenzene''' is an [[Organic compound|organic]] [[chemical compound]] which is an [[aromatic]] [[hydrocarbon]]. Its major use is in the [[petrochemical]] industry as an intermediate compound for the production of [[styrene]], which in turn is used for making [[polystyrene]], a commonly used [[plastic]] material. Although often present in small amounts in [[crude oil]], ethylbenzene is produced in bulk quantities by combining the petrochemicals [[benzene]] and [[ethylene]] in an acid-catalyzed [[chemical reaction]]. Catalytic [[dehydrogenation]] of the ethylbenzene then gives [[hydrogen]] [[gas]] and styrene, which is [[vinyl]]benzene. Ethylbenzene is also an ingredient in some paints, and solvent grade [[xylene]] (xylol) nearly always contains ethylbenzene as a contaminant, to the extent of a few percent.
