| 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. |
