Cumene process
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 mMaterial Balances Design Problem Cumene Production Background Cumene (isopropyl benzene) is produced by reacting propylene and benzene over an acid catalyst.

Solid Acid Catalysts for the Hock Cleavage of Hydroperoxides
The oxidation of cumene and following cleavage of cumene hydroperoxide (CHP) with sulfuric acid (Hock rearrangement) is still, by far, the dominant synthetic route to produce phenol. In 2020, the global phenol market reached a value of 23.3 billion US$ with a projected compound annual growth rate of 3.4% for 2020–2025. Abstract— In the large-scale production of phenol by the cumene method, an important constituent is the separation of multicomponent mixtures containing the target products and various impurities. The potential of distillation processes of a specific composition is determined by the structure of the vapor–liquid equilibrium diagram Development of Flowsheet of Separation of a Phenol Production
