1-METHYL-1-CYCLOHEXENE Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Physical properties

Clear, colorless, very flammable, watery liquid with a characteristically unpleasant, aromatic hydrocarbon-type odor.

Uses

1-Methyl-1-cyclohexene (2,3,4,5-Tetrahydrotoluene) was used to study the secondary organic aerosol (SOA) yields from the ozonolysis of cycloalkenes.

Synthesis Reference(s)

The Journal of Organic Chemistry, 45, p. 917, 1980 DOI: 10.1021/jo01293a030

General Description

1-Methyl-1-cyclohexene (2,3,4,5-Tetrahydrotoluene) is a sterically hindered, unactivated alkene.

Environmental Fate

Photolytic. Atkinson (1985) reported a rate constant of 9.45 x 10^-11 cm³/molecule?sec for the reaction of 1-methylcyclohexene with OH radicals in the atmosphere.

Purification Methods

Free it from hydroperoxides by passing through a column containing basic alumina or refluxing with cupric stearate, filter and fractionally distil it from sodium. [Vogel J Chem Soc 1332 1938, Cope et al. J Am Chem Soc 79 4729 1957, Beilstein 5 III 197, 5 VI 245.]
