  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 ...

    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 ...

  4. Cumene - Wikipedia

    en.wikipedia.org/wiki/Cumene

    It is a flammable colorless liquid that has a boiling point of 152 °C. Nearly all the cumene that is produced as a pure compound on an industrial scale is converted to cumene hydroperoxide, which is an intermediate in the synthesis of other industrially important chemicals, primarily phenol and acetone (known as the cumene process).

  5. Dow process (phenol) - Wikipedia

    en.wikipedia.org/wiki/Dow_process_(phenol)

    When 1-[14 C]-1-chlorobenzene was subjected to aqueous NaOH at 395 °C, ipso substitution product 1-[14 C]-phenol was formed in 54% yield, while cine substitution product 2-[14 C]-phenol was formed in 43% yield, indicating that an elimination-addition (benzyne) mechanism is predominant, with perhaps a small amount of product from addition ...

    Phenol is also a versatile precursor to a large collection of drugs, most notably aspirin but also many herbicides and pharmaceutical drugs. Phenol is a component in liquid–liquid phenol–chloroform extraction technique used in molecular biology for obtaining nucleic acids from tissues or cell culture samples.
