Cumene hydroperoxide, or isopropylbenzene, is an organic compound consisting of a benzene ring with an isopropyl group attached to it. It is a colorless, volatile, flammable liquid with a characteristic gasoline-like odor. Cumene is found naturally in crude oil and some refined fuels, and is used as an important chemical intermediate in the production of many industrial products.

Cumene Properties

Chemical Formula: C₉H₁₂
Physical State: Colorless Liquid
Odor: Characteristic, gasoline-like odor
Density: Less than water
Flammability: Highly flammable
Solubility: Insoluble in water, but soluble in organic solvents such as benzene and toluene.

Uses of Cumene

Phenol and Acetone Production: The most important use of cumene is in the production of phenol and acetone. In the cumene process, cumene reacts with oxygen to form cumene hydroperoxide. This hydroperoxide is then decomposed into phenol and acetone. Phenol and acetone are used as raw materials in the production of many products, including plastics, resins, dyes, and pharmaceuticals.
Production of Other Chemical Compounds: Cumene is also used to produce other chemical compounds such as alpha-methylstyrene, styrofoam, and acetophenone.
Solvent: Cumene is used as a solvent for some resins, dyes, and coatings.
Fuel Additive: Cumene is used as an additive to improve the octane number of gasoline.

Safety and Hazards

Cumene is a hazardous chemical and precautions should be taken when working with it. Inhalation of cumene vapors can cause respiratory irritation, dizziness, headache, and even loss of consciousness. Skin contact with cumene can cause irritation and burns. Ingestion of cumene can also cause poisoning.
