Acetone (dimethyl ketone, 2-propanone, CH 3 COCH 3) is a clear, colorless, volatile liquid with a sweet odor. It is both the simplest aliphatic ketone and the most commercially important. Nearly all world production of acetone is via cumene peroxidation, as a coproduct with phenol.
The vast majority of phenol is made by the cumene process. The process has three stages: a) production of cumene. b) conversion of cumene to cumene hydroperoxide. c) decomposition of cumene hydroperoxide (a) Production of cumene. Cumene is the name often given to (1-methylethyl)benzene (isopropylbenzene).

The main process for manufacturing cumene involves the reaction of propylene and benzene in the presence of phosphoric acid-based catalysts or, more recently, zeolite catalysts. The cumene is oxidised in the liquid phase to cumene hydroperoxide which is then cleaved in the presence of sulphuric acid to phenol and acetone.
Cumene peroxidation process is a process involves the liquid phase air oxidation of cumene to cumene peroxide, which in turn is decomposed to phenol and acetone by the action of acid.During the cumene peroxidation process, there are two main raw materials used in this process which are cumene and oxygen. Oxygen is a gas form fluid.
