1,1,3-TRIMETHYLCYCLOHEXANE Chemical Properties,Usage,Production

Chemical Properties

Clear, colorless, flammable liquid with an odor resembling methylcyclohexane.

Environmental Fate

Chemical/Physical. Complete combustion in air produces carbon dioxide and water vapor. 1,1,3-Trimethylcyclohexane will not hydrolyze because it does not contain a hydrolyzable functional group.
