What is cumene used for?

Cumene, also known as isopropylbenzene, 2-phenylpropane or (1-methylethyl) benzene, is widely used as a chemical intermediate in the production of phenol and acetone. Cumene is also used as a thinner for paints, lacquers, and enamels and it is a natural component of coal tar and petroleum.

Is cumene hazardous?

* Exposure can cause headache, dizziness, poor coordination and even passing out. * Cumene Hydroperoxide may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash. * Cumene Hydroperoxide is a HIGHLY REACTIVE CHEMICAL and a DANGEROUS EXPLOSION HAZARD.

What is cumene made of?

Cumene is produced from the distillation of coal tar and petroleum fractions or by the alkylation of benzene with propene using an acidic catalyst. It is used almost exclusively to produce phenol and acetone. Cumene occurs naturally in crude oil, and is found in the environment in plants and foodstuff.

Is cumene a carcinogen?

Cumene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals. Cumene caused tumors at several tissue sites, including lung and liver in mice and kidney in male rats.

Does cumene evaporate?

Cumene evaporates when exposed to air. In the air it is reacted quickly into other chemicals, in the water and soil bacteria break it down. It has moderate acute (short-term) toxicity on aquatic life, and high acute toxicity to birds. It has moderate chronic (long-term) toxicity to aquatic life.

What does cumene smell like?

Cumene, also known as isopropylbenzene, 2-phenylpropane, or (1-methylethyl) benzene, is a colorless, volatile liquid with a gasoline-like odor. It is a natural component of coal tar and crude oil, and also can be used as a blending component in gasoline.

Is cumene isopropyl benzene?

Cumene is a common name for isopropylbenzene, an organic compound.

How do you get phenol from cumene?

To prepare phenol, cumene is first oxidized in the presence of air of cumene hydro-peroxide. Then, cumene hydroxide is treated with dilute acid to prepare phenol and acetone as by-products.

How do you get cumene?

Cumene is an organic compound obtained by Friedel-Crafts alkylation of benzene with propylene. Upon oxidation of cumene (isopropylbenzene) in the presence of air, cumene hydroperoxide is obtained. Upon further treatment of cumene hydroperoxide with dilute acid, phenols are obtained.

What does cumene look like?
