C6H5CH(CH3)2 A colorless, oily benzenoid hydrocarbon cooling at 152.4°C; used as an additive for high-octane motor fuel.

Cumene

 

(also isopropylbenzene), C6H5CH(CH3)2, a colorless liquid with a pleasant odor. Melting point, —96.03°C; boiling point, 152.39°C; density, 0.8618 g/cm3 (at 20°C); and refractive index, nD20, 1.4913.

Cumene is readily soluble in organic solvents and poorly soluble in water. It forms explosive vapor-air mixtures (flash point, 38°C). Internal introduction of cumene leads to acute and chronic damage of the hematopoietic organs. Cumene is obtained by vapor-phase (in the presence of phosphoric acid) or liquid-phase (in the presence of AlCl3) alkylation of benzene by propylene. Cumene is used as a solvent and a high-octane additive to aviation gasolines; it is also used in the production of phenol and acetone.
