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. WebThe present invention is directed to the selective hydro genation of alpha-methyl-styrene to cumene using a com bined catalyst system having a nickel-based catalyst and a noble-metal catalyst. The present invention provides, in one embodiment, a process for the selective hydrogenation of alpha-methyl styrene (AMS) to cumene.
