Cumene on reaction with oxygen
Did you know?
Cumene is formed in the gas-phase Friedel–Crafts alkylation of benzene by propene. Benzene and propene are compressed together to a pressure of 30 standard atmospheres at 250 °C in presence of a catalytic Lewis acid. Phosphoric acid is often favored over aluminium halides. Cumene is oxidized in air, which removes the tertiary benzylic hydrogen from cumene and hence forms a cumene WebApr 15, 2024 · Cumene on reaction with oxygen followed by hydrolysis gives. asked Aug 20, 2024 in Chemistry by Punamsingh (96.1k points) class-12; alcohols; phenols-and …

WebCumene (isopropylbenzene) is oxidised in the presence of air to produce cumene hydroperoxide. Phenol is produced by further treating cumene hydroperoxide with dilute acid. One of the by-products of this process is the production of acetone in large amounts. Therefore, it is necessary to purify the phenol that results from these processes. 2. biometric handgun safes made in usaWebAug 20, 2024 · Cumene on reaction with oxygen followed by hydrolysis gives A. `CH_(3)OH` and `C_(6)H_(5)COCH_(3)` B. `C_(6)H_(5)OH and (CH_(3))_(2)O` C. … biometric handgunWebreaction in which a hydrogen atom of an aromatic ring is replaced by an electrophile • In this section: – several common types of electrophiles ...
