Cumene with o2
WebCumene is used as a thinner for paints, lacquers, and enamels and as a component of high octane fuels. (1,2,4) Cumene is also used in the manufacture of phenol, acetone, … 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
