Cumene hydroperoxide is the organic compound with the formula C6H5C(CH3)2OOH; this oily liquid is classified as an organic hydroperoxide.[2] Products of decomposition of cumene hydroperoxide are methylstyrene, acetophenone, and 2-phenylpropan-2-ol.[3]

It is produced by treatment of cumene with oxygen, an autoxidation. At temperatures >100 °C, oxygen is passed through liquid cumene:[4]

Dicumyl peroxide is a side product.

Applications

Cumene hydroperoxide is an intermediate in the cumene process for producing phenol and acetone from benzene and propene.

Overview of the cumene process

Cumene hydroperoxide is a radical initiator for production of acrylates.[5]

Cumene hydroperoxide is involved as an organic peroxide in the production of propylene oxide by the oxidation of propene. This technology was commercialized by Sumitomo Chemical.[6]

The oxidation by cumene hydroperoxide of propene affords propylene oxide and the byproduct 2-phenylpropan-2-ol. The reaction follows this stoichiometry:

Dehydrating and hydrogenating cumyl alcohol recycles the cumene.

Safety

Cumene hydroperoxide, like all organic peroxides, is potentially explosive. It is also toxic, corrosive and flammable as well as a skin-irritant.[7]
