- Isobutylene (or
2-methylpropene) is a hydrocarbon of significant industrial importance.
- It is a four-carbon
branched alkene (olefin), one of the four isomers of
butylene.
- Isobutylene can be
isolated from refinery streams by reaction with sulfuric acid, but the
most common industrial method for its production is by catalytic
dehydrogenation of isobutane.
- Alkylating
isobutylene mixed with normal olefins will result in the production of
more heavy alkylate due to isobutylene - n-olefin reactions.
- There are two
principle sources of highly purity isobutylene. One is the decomposition
of MTBE to isobutylene and methanol, and the other is the
dehydrogeneration of isobutane.
- Distillation is the
another possibility for the production of isobutylene. For this FCC
butenes should be partially hydrogeneted to both eliminate most of the
butadiene and also isomerize most 1-butene to 2-butene.
- Isobutylene is the
most explored monomer which is polymerized by controlled/living cationic
polymerization.
- At standard
temperature and pressure it is a colorless flammable gas.
- Isobutylene is used
as an intermediate in the production of a variety of products. It is
reacted with methanol and ethanol manufacture of gasoline oxygenates
methyl tert-butyl ether (MTBE) and ethyl tert-butyl ether (ETBE),
respectively.
- Isobutylene is also
used in the production of methacrolein. Polymerization of isobutylene
produces butyl rubber (polyisobutylene).
- Antioxidants such as
butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) are
produced by Friedel-Crafts alkylation of phenols using
isobutylene.
