| | 1-METHYL-1-CYCLOHEXENE Usage And Synthesis |
| 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.
