Isobutylene
Isobutylene is a colorless, flammable gas.
Isobutylene
Formula: C₄H₈
Isobutylene (C₄H₈) is used in the production of a variety of products. It is alkylated with butane to produce isooctane or dimerized to disobutylene (DIB) and then hydrogenated to make isooctane, a fuel additive.
Isobutylene is also used in the production of methacrolein. Polymerization of isobutylene produces butyl rubber (polyisobutylene or PIB). The most important application of butyl rubber is the manufacture of tires for cars and other vehicles. Other applications of butyl rubber, polybutene and polyisobutylene are lubricants (motor oils), adhesives, sealants and coatings. Isobutylene is also used for the production of anti-oxidants, fragrances and gas odorized products.
