cumene process

Chemistry

An industrial process for making phenol from benzene. A mixture of benzene vapour and propene is passed over a phosphoric acid catalyst at 250°C and high pressure
$C_{6} H_{6} + {CH}_{3} CH = {CH}_{2} \to C_{6} H_{5} CH {({CH}_{3})}_{2}$
The product is called cumene, and it can be oxidized in air to a peroxide, C₆H₅C(CH₃)₂O₂H. This reacts with dilute acid to give phenol (C₆H₅OH) and propanone (acetone, CH₃OCH₃), which is a valuable by-product.

Chemical Engineering

A process used for the production of phenol from benzene. The process, developed in the 1940s, involves reacting benzene and propene (propylene) vapour over a phosphoric acid catalyst at high temperature and pressure to produce cumene (isopropyl benzene):
$C_{6} H_{6} + C H_{3} C H : C H_{2} \to C_{6} H_{5} C H {(C H_{3})}_{2}$

The cumene is then oxidized in air and reacted with dilute acid to yield phenol.
