Cumene to alpha methyl styrene
WebMost of Cumene produced is oxidized to obtain cumene hydroperoxide, which, in turn, is destined for cleavage to produce phenol and acetone as a co-product or as a reactant in polymerizations. During the first process, α-methylstyrene can also be obtained, which, when added to cumene hydroperoxide, generates dicumyl peroxide.
