phenol by cumene process:

About this site

The cumene process (cumene–phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene. The term stems from cumene (isopropyl benzene), the intermediate material during the process. It was invented by R. Ūdris and P. Sergeyev in 1942 (USSR)., and independently by Heinrich Hock in 1944

How is phenol manufactured by Cumene process?

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
