WebOct 31, 2005 · Alpha-methylstyrene was successfully hydrogenated to cumene using both catalytic transfer hydrogenation and mediator assisted electrochemical hydrogenation. Complete conversion was achieved at a mediator concentration of 0.5M and at an applied potential of -1.3V vs. SCE at 60°C. 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.
