Isopropylibentseeni

Isopropylibentseeni, also known as cumene, is an organic compound with the chemical formula C9H12. It is a colorless liquid that has a characteristic sweet odor. Isopropylibentseeni is an aromatic hydrocarbon, specifically an alkylbenzene, meaning it consists of a benzene ring with an isopropyl group attached. Its IUPAC name is 2-phenylpropane.

Isopropylibentseeni is primarily produced industrially as a co-product in the synthesis of phenol and acetone from benzene and propylene, a process known as the cumene process. This process involves the alkylation of benzene with propylene to form cumene, followed by the oxidation of cumene to cumene hydroperoxide, which is then cleaved into phenol and acetone. The cumene process is the dominant method for producing phenol and acetone worldwide.

The primary use of isopropylibentseeni is as an intermediate in the production of phenol and acetone. These chemicals are vital for the manufacturing of a wide range of products, including plastics like polycarbonate and epoxy resins, as well as pharmaceuticals, detergents, and solvents. Isopropylibentseeni itself can also be used as a solvent and as an additive in gasoline to increase its octane rating. Due to its flammability, it is handled with appropriate safety precautions in industrial settings.
