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 …
Feb 25, 2005· As shown in the flow diagram again for the Sunoco/UOP process, the spent air streams from both oxidizers are combined and routed through a water-cooled condenser, a chilled condenser and an entrainment separator for the maximum removal of hydrocarbon and cumene. From the entrainment separator, the air flows to the charcoal absorbers.

The cumene process is used to convert benzene and propene in the presence of oxygen to phenol and acetone via the following reaction. This reaction is carried out in with excess benzene and excess oxygen to ensure that no side reactions occur. A 1.13 ratio of benzene to propene is fed to a reactor in the presence of 28.5% excess air (N2 and O2).
Feedstock and Steam Consumption for the Process as a Whole It is seen from the practical data on the selectivity of the basic steps of the phenol process and from the values of the physical and chemical losses at the auxiliary steps of the process, the overall selectivity (for phenol) of the phenol process on the fed cumene basis is 93.9 mol ...
