Hazard Information | Back Directory | [Chemical Properties]
Clear, colorless, flammable liquid with a mild characteristic odor | [Definition]
ChEBI: Trans-1,2-dimethylcyclohexane is a cycloalkane. | [Source]
Component of gasoline (quoted, Verschueren, 1983) | [Environmental Fate]
Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. trans-
1,2-Dimethylcyclohexane will not hydrolyze because it has no hydrolyzable functional group. |
