WHAT IS ISOBUTENE?
Isobutene (also 2-methylpropene or isobutylene) is an isomeric C4 hydrocarbon. The colorless gas can be easily liquified under pressure. Due to its reactivity and properties, this gas is a versatile and valuable basic building block in chemical syntheses.
Isobutene is a starting material or monomer for the production of various polymers or final products such as: Butyl Rubber, polyisobutylene, polymethylacrylate. Further it is used as intermediate for the production of various chemical substances and products, for example antioxidants, tert-butyl ethers and esters, tert-butyl-alcohol.
WHAT IS ISOBUTENE USED FOR?
The polymer polyisobutene is based on isobutene/ isobutylene. Polyisobutene is mainly used as a lubricant and fuel additive. Thus, for example, isobutene ensures that combustion engines run efficiently. While maintaining engine performance, this liquid gas reduces fuel consumption and harmful emissions.
Isobutene-based rubber is also used in the production of tires, hoses or adhesives and sealants. In car tires, butyl rubber is used for air-impermeable inner coatings.
Furthermore, isobutene is also an important intermediate to produce antioxidants.
Isobutene is also essential building block for citral, linalool and geraniol applications. The liquid gas gives dishwashing detergents, among others, a pleasant citrus, lavender or rose scent. Moreover, isobutene is used for vitamin A synthesis. As you can see, isobutene really is a gas for all occasions.
