What is Triisobutylene used for?
CAS Number: 7756-94-7
Molecular Weight: 168.32
Molecular Formula: C12H24
Triisobutylene (triisobutene) is a admixture of awful angled C12 isoolefins. It is acclimated as a actinic average in the assembly of tert- dodecylmercaptan - an abetting in polymer allure - and tridecyl alcohol/acid (plasticisers and bread-and-butter components).
Isobutylene (or 2-methylpropene) is a hydrocarbon of cogent automated importance. It is a four-carbon angled alkene (olefin), one of the four isomers of butylene. At accepted temperature and burden it is a achromatic combustible gas.
Isobutylene is acclimated as an average in the assembly of a array of products. It is reacted with booze and booze in the accomplish of the gasoline oxygenates methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE), respectively. Alkylation with butane produces isooctane, addition ammunition additive. Isobutylene is aswell acclimated in the assembly of methacrolein. Polymerization of isobutylene produces butyl elastic (polyisobutylene). Antioxidants such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) are produced by Friedel-Crafts alkylation of phenols application isobutylene.
Isobutylene can be abandoned from refinery streams by acknowledgment with sulfuric acid, but the a lot of accepted automated adjustment for its assembly is by catalytic dehydrogenation of isobutane. In the 1990s, the assembly of isobutylene added badly as the appeal for oxygenates such as MTBE grew. Key manufacturers of this artefact are Texas Petrochemicals(TPC Group) and Lyondell in North America.
Isobutylene is a awful combustible gas and presents an access danger. Usually stored as a compressed, abounding gas, if appear it may aftermath an oxygen-deficient atmosphere that presents an asphyxiation hazard.
