WebOther names: Cumene; Cumol; Isopropylbenzene; 2-Phenylpropane; (1-Methylethyl)benzene; Isopropylbenzol; Benzene, isopropyl-; Cumeen; … Cumene (isopropylbenzene) is an organic compound that contains a benzene ring with an isopropyl substituent. 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 … See more Commercial production of cumene is by Friedel–Crafts alkylation of benzene with propylene. Cumene producers account for approximately 20% of the global demand for benzene. The original route for manufacturing of … See more • Pseudocumene See more Depending on the conditions, autoxidation of cumene gives dicumyl peroxide or cumene hydroperoxide. Both reactions exploit the weakness of the tertiary C-H bond. The tendency of cumene to form peroxides by autoxidation poses safety concerns. Tests for … See more • National Pollutant Inventory - Cumene fact sheet • Cumene Production from Benzene and Propylene Using Aluminum Chloride Catalyst See more
Benzene, (1-methylethyl)- - NIST
Cyclohexylbenzene can replace isopropylbenzene. Via the Hock rearrangement, cyclohexylbenzene hydroperoxide cleaves to give phenol and cyclohexanone. Cyclohexanone is an important precursor to some nylons. Starting with the alkylation of benzene with mixture of 1 and 2-butenes, the cumene process produces phenol and butanones.

WebCumene Manufacture. A more complex example is the manufacture of cumene (isopropyl benzene) by the alkylation of benzene with propylene, taken from the 1997 National Student Design Competition of the AIChE. Cumene is widely used to make acetone and phenol. The fresh feeds are as follows, where the benzene feed is nearly pure, but a … north face crestone backpack review
