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 ...
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:
Phenol and its vapors are corrosive to the eyes, the skin, and the respiratory tract. [60] Its corrosive effect on skin and mucous membranes is due to a protein-degenerating effect. [49] Repeated or prolonged skin contact with phenol may cause dermatitis, or even second and third-degree burns. [61] Inhalation of phenol vapor may cause lung ...
A phenol peel is one of the strongest chemical peels you can get. Here's a rundown of the risks, benefits, according to a dermatologist and two estheticians.
Cumene hydroperoxide is the organic compound with the formula C 6 H 5 C(CH 3) 2 OOH; this oily liquid is classified as an organic hydroperoxide. [2] Products of decomposition of cumene hydroperoxide are methylstyrene, acetophenone, and 2-phenylpropan-2-ol. [3] It is produced by treatment of cumene with oxygen, an autoxidation.

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.
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.
