Editing Butanone (section)

==Production==
Butanone may be produced by oxidation of [[2-butanol]]. The [[dehydrogenation]] of 2-butanol is [[catalyst|catalysed]] by [[copper]], [[zinc]], or [[bronze]]:
:CH<sub>3</sub>CH(OH)CH<sub>2</sub>CH<sub>3</sub>   →   CH<sub>3</sub>C(O)CH<sub>2</sub>CH<sub>3</sub>  +  H<sub>2</sub>

This is used to produce approximately 700 million kilograms yearly. Other syntheses that have been examined but not implemented include [[Wacker oxidation]] of [[2-butene]] and oxidation of [[isobutylbenzene]], which is analogous to the industrial production of [[acetone]].<ref name=Ullmann/> The [[cumene process]] can be modified to produce phenol and a mixture of acetone and butanone instead of only phenol and acetone in the original.<ref name=cumeneprocess>{{Cite web |url=http://www.chemistry.org/portal/a/c/s/1/feature_pro.html?id=c373e908e6e847ac8f6a17245d830100 |title=Direct Routes to Phenol |access-date=2017-12-13 |archive-url=https://web.archive.org/web/20070409042033/http://www.chemistry.org/portal/a/c/s/1/feature_pro.html?id=c373e908e6e847ac8f6a17245d830100 |archive-date=2007-04-09 |url-status=dead }}</ref>

Both liquid-phase oxidation of heavy [[naphtha]] and the [[Fischer–Tropsch]] reaction produce mixed oxygenate streams, from which 2-butanone is extracted by fractionation.<ref>Ashford's Dictionary of Industrial Chemicals, Third edition, 2011, {{ISBN|978-0-9522674-3-0}}, pages 6013-4</ref>
