2metüülpropeen

2-methylpropene, also known as isobutylene, is an organic compound with the chemical formula (CH3)2C=CH2. It is a colorless gas at room temperature and pressure, and it is highly flammable. 2-methylpropene is an alkene, characterized by the presence of a carbon-carbon double bond. It is one of the four isomers of butene. It is primarily produced as a byproduct of petroleum refining, specifically from the catalytic cracking of hydrocarbons. It can also be produced through the dehydration of tert-butyl alcohol.

The primary industrial application of 2-methylpropene is as a feedstock for the production of other chemicals. It is used in the synthesis of methyl tert-butyl ether (MTBE), a gasoline additive that was formerly widely used to boost octane ratings but has been phased out in many regions due to environmental concerns. It is also a precursor for the production of isoprene, a key component in synthetic rubber, and polyisobutylene, a polymer used in lubricants and adhesives. 2-methylpropene can be polymerized to form polyisobutylene, a versatile polymer. It is also used in the production of antioxidants and in alkylation processes.
