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 ...

The green-blue coloring with iron(III)chloride, which is characteristic for phenols, does not occur in 2,4,6-TTBP. The compound is oxidizable in air but practically non-biodegradable. [7] As an electron-rich aromatic, 2,4,6-tri-tert-butylphenol can also be easily oxidized electrochemically. [8]
An excess of phenol is used to ensure full condensation and to limit the formation of byproducts, such as Dianin's compound. BPA is fairly cheap to produce, as the synthesis benefits from a high atom economy and large amounts of both starting materials are available from the cumene process. [7]
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:
It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [2]
Cumene hydroperoxide is an intermediate in the cumene process for producing phenol and acetone from benzene and propene. 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 ...
