What is the common name of isopropylbenzene?
Isopropylbenzene, also known as 2-phenylpropane or benzene, isopropyl, belongs to the class of organic compounds known as cumenes.
Is cumene a liquid?
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.
Why isopropyl benzene is called cumene?
Cumene (isopropylbenzene) is an organic compound that is based on an aromatic hydrocarbon with an aliphatic substitution. It is a constituent of crude oil and refined fuels. It is a flammable colorless liquid that has a boiling point of 152 °C….Cumene.

Where is cumene found?
crude oil
5.1. Cumene occurs naturally in crude oil, and is found in the environment in plants and foodstuff. Cumene is primarily released into the environment during its production and use, and from emissions from gasoline engines.
How does cumene affect the body?
Acute (short-term) inhalation exposure to cumene may cause headaches, dizziness, drowsiness, slight incoordination, and unconsciousness in humans. Cumene has a potent central nervous system (CNS) depressant action characterized by a slow induction period and long duration of narcotic effects in animals.
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.
Where is cumene used?
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.
Where is cumene produced?
5.1. 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.
What products contain cumene?
Cumene is used to manufacture other chemicals such as phenol, acetone, acetophenone, and methyl styrene. It is used as a thinner in paints, lacquers, and enamels. It is a component of high octane motor fuels. Cumene in used in the manufacture of rubber, iron and steel, and pulp and paper.
What are the uses of cumene?
Is cumene hazardous?
Does cumene contain benzene?
Cumene is an alkylbenzene that is benzene carrying an isopropyl group.
What is Kolbe reaction in simple words?
Definition of Kolbe reaction 1 : the synthesis of a hydrocarbon (as ethane) by the electrolysis of a salt (as sodium acetate) 2 : the synthesis of salicylic acid by heating a mixture of sodium phenoxide and carbon dioxide under pressure at 180° to 200° C.
What is called Kolbe reaction?
The Kolbe–Schmitt reaction or Kolbe process (named after Hermann Kolbe and Rudolf Schmitt) is a carboxylation chemical reaction that proceeds by heating sodium phenoxide (the sodium salt of phenol) with carbon dioxide under pressure (100 atm, 125 °C), then treating the product with sulfuric acid.
Is cumene a petroleum product?
Cumene is manufactured from the distillation of coal tar and petroleum fractions, or is produced by the alkylation of benzene with propene using an acidic catalyst (European Commission, 2001).
