Description

Isobutylene, also known as 2-methylpropene, is a highly reactive branched alkene with the formula CH2=C(CH3)2. It is a colorless gas at room temperature and is widely used in the chemical industry. Isobutylene is produced as a byproduct of the steam cracking of hydrocarbons, particularly in the production of ethylene and propylene. It can also be synthesized from tertiary butanol through dehydration. Isobutylene is a key intermediate in the production of various important chemicals, including methyl tert-butyl ether (MTBE), a gasoline additive, polyisobutylene, a synthetic rubber, and butyl rubber. The polymerisation of isobutylene yields polyisobutylene, a synthetic rubber with excellent resistance to oxidation and weathering. This makes it valuable for applications such as adhesives, sealants, and lubricants. Isobutylene is also used in the production of butyl rubber, a synthetic rubber with excellent impermeability to gases, making it suitable for applications such as inner tubes and tyre liners. Its reactivity and versatile applications make it a significant component in the chemical industry. Research on isobutylene focuses on developing new and efficient synthetic methods, exploring its use in novel polymer and material synthesis, and investigating its potential applications in alternative fuels and sustainable chemistry.'
