2phenylpropane

2-Phenylpropane, also known as cumene, is an organic compound with the chemical formula C9H12. It is a clear, colorless liquid with a distinct aromatic odor. Cumene is a derivative of propane where a phenyl group is attached to the second carbon atom of the propane chain. This structure makes it an alkylbenzene.

Cumene occurs naturally in coal tar and petroleum. Industrially, it is produced in large quantities through the alkylation of benzene with propylene, typically using solid acid catalysts like zeolites or phosphoric acid. This process is a key component of the petrochemical industry.

The primary industrial use of 2-phenylpropane is as an intermediate in the production of phenol and acetone. This process, known as the cumene process, involves the oxidation of cumene to cumene hydroperoxide, followed by acid-catalyzed cleavage to yield phenol and acetone. These two chemicals are vital for manufacturing a wide range of products including plastics, resins, and solvents.

Beyond its role in phenol and acetone production, cumene also finds applications as a solvent for resins, lacquers, and enamels. It can also be used as an additive in fuels to increase octane rating. Due to its flammability, cumene should be handled with care and stored in well-ventilated areas away from ignition sources.
