  2. Cumene process - Wikipedia

    en.wikipedia.org/wiki/Cumene_process

    This latter cumene converts into cumene radical and feeds back into subsequent chain formations of cumene hydroperoxides. A pressure of 5 atm is used to ensure that the unstable peroxide is kept in liquid state. Cumene hydroperoxide undergoes a rearrangement reaction in an acidic medium (the Hock rearrangement) to give phenol and acetone. In ...

  3. Acetophenone - Wikipedia

    en.wikipedia.org/wiki/Acetophenone

    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:

  4. Raschig–Hooker process - Wikipedia

    en.wikipedia.org/wiki/Raschig–Hooker_process

    [6] [7] Due to the two step nature, the Raschig–Hooker process can be used to produce either chlorobenzene or phenol. Reaction scheme of the Raschig-Hooker process. The Raschig–Hooker process's ability to make phenol makes it comparable to other methods, such as the Dow and Bayer process, which also converts benzene into phenol. In fact ...

  5. Cumene - Wikipedia

    en.wikipedia.org/wiki/Cumene

    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.

  6. 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:

  7. Petrochemical - Wikipedia

    cumene – isopropylbenzene; a feedstock in the cumene process. phenol – hydroxybenzene; often made by the cumene process; acetone – dimethyl ketone; also often made by the cumene process; bisphenol A – a type of "double" phenol used in polymerization in epoxy resins and making a common type of polycarbonate

    en.wikipedia.org/wiki/Phenol

    Phenol is an organic compound appreciably soluble in water, with about 84.2 g dissolving in 1000 ml (0.895 M).Homogeneous mixtures of phenol and water at phenol to water mass ratios of ~2.6 and higher are possible.
