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 ...
First stage of Hock process: alkylation of benzene with propylene. Second stage of Hock process: autoxidation of cumene. The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene.
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 ...

n-Propylbenzene is an aromatic hydrocarbon with the formula C 6 H 5 CH 2 CH 2 CH 3.The molecule consists of a propyl group attached to a phenyl ring. It is a colorless liquid. A more common structural isomer of this compound is cumene.
(Isopropylbenzene) There are also a large number of branched or ring alkanes that have specific names, e.g., tert-butyl , bornyl , cyclohexyl , etc. There are several functional groups that contain an alkene such as vinyl group , allyl group , or acrylic group .
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 called the Cumene-Phenol plant because of the intermediate materials is cumene or isopropylbenzene in the cumene process. It produces equimolar amounts of phenol and acetone. It was the only Cumene-Phenol plant built in Australia. Some cumene-hydroperoxide an organic peroxide was also sold. There are 7 units in this plant
