| Application: | Diisobutylene, an alkene, may be used in the following studies: • To compose alternalte diesel fuel. • As fuel in single-cylinder engine; exhaust generated from combustion due to the burning of fuel has been reported to contain high concentrations of olefins.1 • Preparation of mono- and dialkylated diphenylamines. |
| General description: | Diisobutylene is an acyclic alkene. It is composed of a mixture of 2,4,4-trimethyl-1-pentene and 2,4,4- trimethyl-2-pentene (isomeric forms of diisobutylene). It is isostructural to to iso-octane. It can be synthesized from tertiary butyl alcohol. |
