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. This process converts two relatively cheap starting materials, benzene and propylene, into two m… WebThe Hock process to produce phenol and acetone from low cost reagents, oxygen, and sulfuric acid was discovered by Hock and Lang in 1944. The phenol produced by the Hock process approaches 99.99 wt % with total impurities of only 60 ppm. The process starts with cumene being oxidized to form an intermediate compound called cumene
