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.
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 ...
Diisopropylbenzenes typically arise by alkylation of benzene or isopropylbenzene with propylene: C 6 H 6 + CH 3 CH=CH 2 → C 6 H 5 CH(CH 3) 2 C 6 H 5 CH(CH 3) 2 + CH 3 CH=CH 2 → C 6 H 4 (CH(CH 3) 2) 2. These alkylations are catalyzed by various Lewis acids, such as aluminium trichloride. They can also be prepared and transformed by ...

Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor. [9]Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and chloroform, demonstrating its ability to dissolve a wide range of substances including ethyl cellulose, polyvinyl butyral, oils, alkaloids, and natural ...
It is used commercially in perfumes and other cosmetics. It has been shown that cuminaldehyde, as a small molecule, inhibits the fibrillation of alpha-synuclein , [ 2 ] which, if aggregated, forms insoluble fibrils in pathological conditions characterized by Lewy bodies , such as Parkinson's disease , dementia with Lewy bodies [ 3 ] and ...
