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 WebCumene on reaction with oxygen followed by hydrolysis gives: Hard.

Webin the meta example, the benzene carbon that is attached to the oxygen already has four bonds (one single bond to the oxygen, one single bond to another carbon in the ring, and a double bond to a second carbon in the ring). That is, that carbon already has a full octet so can't accept any more electrons to form a double bond with oxygen.

Cumene on reaction with oxygen

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. WebGiven the second order rate constants for the reactions of acetone with 1 Δ g (Datta and Rao 1979) and O(3 P) (Lee and Timmons 1977; Singh et al. 1994), and the concentrations of singlet molecular and atomic oxygen in the atmosphere (Graedel 1978), these reactions are insignificant in determining the fate of acetone in the atmosphere.
