Cumene is oxidized in air, which removes the tertiary benzylic hydrogen from cumene and hence forms a cumene radical: The cumene radical then bonds with an oxygen molecule to give cumene peroxide radical, which in turn forms cumene hydroperoxide (C 6 H 5 C(CH 3) 2 O 2 H) by abstracting a benzylic hydrogen from another cumene molecule. This ...
In commercial applications, the alkylating agents are generally alkenes, some of the largest scale reactions practiced in industry.Such alkylations are of major industrial importance, e.g. for the production of ethylbenzene, the precursor to polystyrene, from benzene and ethylene and for the production of cumene from benzene and propene in cumene process:
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.
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:
Gas stoves can put out more benzene into your home than secondhand smoke from cigarettes, according to a study. Benzene is a known cancer-causing chemical that is widely used across the U.S. to ...
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 ...
The FDA has given the green light to a self-collection solution to test for HPV, making it one of the easiest options available in the U.S. for identifying those at risk of cervical cancer.
At-home test results for both COVID-19 and flu appear in approximately 15 minutes, according to the FDA. ... Based on an FDA analysis, the test correctly identified 99% of negative and 92% of ...
