It is a constituent of crude oil and refined fuels. It is a flammable colorless liquid that has a boiling point of 152 °C. Nearly all the cumene that is produced as a pure compound on an industrial scale is converted to [[cumene hydroperoxide]], which is an intermediate in the synthesis of other industrially important chemicals such as [[phenol]] and [[acetone]]. ==Production== Commercial production of cumene is carried out through the [[catalysis|catalytic]] [[alkylation]] of [[benzene]], with the addition of [[propylene]]. Solid [[phosphoric acid]] (SPA) supported on [[alumina]] can also be used as a catalyst, and this was the case prior to the mid-1990s when [[zeolite]]-based catalysts made the other technique commercially redundant. <ref>[http://www.the-innovation-group.com/ChemProfiles/Cumene.htm The Innovation Group website, page accessed 15/11/07]</ref> ==See also== *[[Cumene process]] ==References== <references/> ==External links== *[http://www.npi.gov.au/database/substance-info/profiles/28.html National Pollutant Inventory - Cumene fact sheet] [[Category:Aromatic hydrocarbons]] [[Category:Hazardous air pollutants]] [[de:Cumol]] [[es:Cumeno]] [[fr:Cumène]] [[it:Cumene]] [[lv:Kumols]] [[nl:Cumeen]] [[ja:クメン]] [[no:Kumen]] [[pl:Kumen]] [[pt:Cumeno]] [[ru:Кумол]]
