Description

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.

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.
