The cumene process method is quite expensive, since it requires the raw materials and extra separation equip-ment to separate acetone from many different materials (Moore & Parker, 2007; Coulson et al., 1999b). Therefore, this study focuses on the more economic method of decomposition of isopropyl alcohol over the cumene process method.

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 …
