CAS 115-11-7: Isobutylene

Description: Isobutylene, also known as 2-methylpropene, is a colorless gas with a slightly sweet odor, classified as an alkene due to its carbon-carbon double bond. Its molecular formula is C4H8, and it is characterized by its branched structure, which contributes to its unique reactivity and properties. Isobutylene is highly flammable and can form explosive mixtures with air, necessitating careful handling and storage. It is soluble in organic solvents but has low solubility in water. This compound is primarily used in the production of various polymers, including butyl rubber and polyisobutylene, and serves as an important intermediate in the synthesis of other chemicals. Isobutylene can undergo various reactions, such as polymerization and oxidation, making it a versatile building block in organic chemistry. Additionally, it is produced through the cracking of petroleum and is a byproduct of gasoline production. Due to its reactivity, isobutylene is also utilized in the manufacture of fuel additives and other industrial applications.
