Cumene with o2

WebVerified by Toppr. Cumene is isopropyl benzene. Cumene in presence of sodium carbonate is oxidised by passing air or oxygen. The catalyst is cobalt naphthenate. Temperature is 423 K. The product cumene hydroperoxide is heated with dilute sulphuric acid. It decomposes to phenol and by product acetone. Acetone is separated by distillation. 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
