Clear, colorless, flammable liquid with a mild characteristic odor. | [Definition]
ChEBI: Cis-1,2-dimethylcyclohexane is a cycloalkane. | [General Description]
cis-1,2-Dimethylcyclohexane has been oxidized by O2 in the presence of iron(II)-bispidine complexes. It has been known to form plastic crystals which can be supercooled to show a glass transition at a temperature Tg. | [Source]
Component of gasoline (quoted, Verschueren, 1983) | [Environmental Fate]
Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. cis-1,2-
Dimethylcyclohexane will not hydrolyze because it has no hydrolyzable functional group. |
