3,3-Dimethylpentane Usage And Synthesis

Chemical Properties

clear colorless liquid

Physical properties

Colorless, mobile liquid with an odor resembling heptane or gasoline. Evaporates when spilled forming combustible vapors.

Uses

3,3-Dimethylpentane Is used in organic synthesis & as gasoline component, as Pharmaceutical intermediates. It was used in the development and evaluation of the epiocular-eye irritation test.

General Description

3,3-Dimethylpentane isomerizes via a methyl shift mechanism on oxygen-exposed tungsten carbides.

Environmental Fate

Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. 3,3- Dimethylbutane will not hydrolyze because it has no hydrolyzable functional group.
