Design and Control of the Cumene Process | Industrial ...

The chemistry of the cumene process features the desired reaction of benzene with propylene to form cumene and the undesirable reaction of cumene with propylene to form p-diisopropylbenzene. Both reactions are irreversible. Since the second has a higher activation energy than the first, low reactor temperatures improve selectivity of cumene.

Greener Industry - Phenol - Production Method 2

Decomposition of cumene hydroperoxide to phenol. The hydroperoxide is mixed with dilute sulphuric acid at 60 - 70ºC, to produce both phenol and propanone (acetone) as products. The decomposition of cumene hydroperoxide to phenol and acetone is often described as a cleavage reaction.

Acetone Production and Manufacturing Process - ICIS Explore

The cumene route, in which the acetone is coproduced with phenol, is the preferred technology because of its lower costs and nearly 90% of acetone is produced this way. 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.

Acetone Production and Manufacturing Process - ICIS Explore

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 | Uses, Benefits, and Chemical Safety Facts

A building-block chemical, almost all cumene (approximately 98 percent) is consumed as a chemical intermediate in the production of phenol and acetone, two chemicals that are widely used to make plastics. Additionally, cumene in minor amounts is used as a solvent during the manufacture of paints, lacquers, and enamels.
