Cumene is oxidized in air, which removes the tertiary benzylic hydrogen from cumene and hence forms a cumene radical: The cumene radical then bonds with an oxygen molecule to give cumene peroxide radical, which in turn forms cumene hydroperoxide (C 6 H 5 C(CH 3) 2 O 2 H) by abstracting a benzylic hydrogen from another cumene molecule. This ...
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.
Benzene is a raw material for dyes and synthetic detergents, and benzene and toluene for isocyanates MDI and TDI used in making polyurethanes. Manufacturers use xylenes to produce plastics and synthetic fibers. Synthesis gas is a mixture of carbon monoxide and hydrogen used to produce methanol and other chemicals.
Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:

Oil prices bounced around quite a bit in 2024. They rallied more than 20% at one point -- topping $85 per barrel -- before cooling off toward the end of the year. Oil was recently below $70 a ...
Donald Trump mocked Canadian Prime Minister Justin Trudeau after his top minister’s surprise resignation following a clash on how to handle the president-elect’s looming tariffs.
Cumene hydroperoxide is an intermediate in the cumene process for producing phenol and acetone from benzene and propene. Cumene hydroperoxide is a free radical initiator for production of acrylates. [5] Cumene hydroperoxide is involved as an organic peroxide in the manufacturing of propylene oxide by the oxidation of propylene. This technology ...
