2. Cumene process - Wikipedia

   en.wikipedia.org/wiki/Cumene_process

   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 ...

3. Friedel–Crafts reaction - Wikipedia

   en.wikipedia.org/wiki/Friedel–Crafts_reaction

   In commercial applications, the alkylating agents are generally alkenes, some of the largest scale reactions practiced in industry.Such alkylations are of major industrial importance, e.g. for the production of ethylbenzene, the precursor to polystyrene, from benzene and ethylene and for the production of cumene from benzene and propene in cumene process:

4. Autoxidation - Wikipedia

   en.wikipedia.org/wiki/Autoxidation

   in the cumene process, isopropylbenzene undergoes autoxidation to give cumene hydroperoxide. This compound is then converted to phenol and acetone, both commodity chemicals. are made from benzene and propylene. Many variations of this reaction have been developed, e.g. use of diisopropylbenzene as a substrate.

5. Petrochemical - Wikipedia

   benzene – the simplest aromatic hydrocarbon ethylbenzene – made from benzene and ethylene styrene – made by dehydrogenation of ethylbenzene; used as a monomer polystyrenes – polymers with styrene as a monomer; cumene – isopropylbenzene; a feedstock in the cumene process. phenol – hydroxybenzene; often made by the cumene process

6. Cumene hydroperoxide - Wikipedia

   en.wikipedia.org/wiki/Cumene_hydroperoxide

   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 ...
