'''Cumene''' is the common name for '''isopropylbenzene''', an [[organic compound]] that is an [[aromatic]] [[hydrocarbon]]. 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>
