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. {| style="text-align: center" |[[Image:ctk-ethylbenzene.png|Ethylbenzene]] |[[Image:ctk-arrow-eq.png]] |[[Image:ctk-styrene.png|Styrene]] |[[Image:ctk-plus.png]] |[[Image:ctk-h2.png|Hydrogen]] |} ==References== {{Citationstyle|date=September 2007}} <references/> * [http://www.epa.gov/ttn/atw/hlthef/ethylben.html EPA Chemical database] * [http://www.intox.org/databank/documents/chemical/ethylben/cie370.htm Intox Chemical database] * [http://www.atsdr.cdc.gov/tfacts110.html Agency for Toxic Substances and Disease Registry] ==External links== * [http://www.npi.gov.au/database/substance-info/profiles/40.html National Pollutant Inventory - Ethybenzene Fact Sheet] *[http://toxnet.nlm.nih.gov/cgi-bin/sis/search/r?dbs+hsdb:@term+@na+Ethylbenzene NLM Hazardous Substances Databank &ndash; Ethylbenzene] [[Category:Aromatic compounds]] [[Category:Hazardous air pollutants]] [[Category:Hydrocarbons]] {{hydrocarbon-stub}} [[bs:Etilbenzen]] [[cs:Ethylbenzen]] [[de:Ethylbenzol]] [[es:Etilbenceno]] [[fr:Éthylbenzène]] [[nl:Ethylbenzeen]] [[ja:エチルベンゼン]] [[no:Etylbenzen]] [[pl:Etylobenzen]] [[pt:Etil benzeno]] [[ru:Этилбензол]] [[fi:Etyylibentseeni]] [[vi:Êtylbenzen]] [[zh:乙苯]]
