TRANS-1,2-DIMETHYLCYCLOHEXANE Usage And Synthesis

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.
