| | 2,3,4-TRIMETHYLPENTANE Usage And Synthesis |
| Chemical Properties | Clear, colorless, flammable, watery liquid with a mild aliphatic hydrocarbon odor resembling
hexane. | | Definition | ChEBI: 2,3,4-trimethylpentane is an alkane that is pentane substituted by a methyl group at positions 2,3 and 4. It is a constituent of gasoline. It has a role as a mammalian metabolite and a nephrotoxic agent. It is an alkane and a volatile organic compound. | | General Description | Kinetics and mechanism of reaction of OH radicals with 2,3,4-trimethylpentane in the presence of NO has been investigated. Kinetics of reactions of C6H5 radical with 2,3,4-trimethylpentane has been measured by cavity ringdown spectrometry. | | Source | Schauer et al. (1999) reported 2,3,4-trimethylpentane in a diesel-powered medium-duty
truck exhaust at an emission rate of 310 μg/km.
California Phase II reformulated gasoline contained 2,3,4-trimethylpentane at a concentration of
13.0 g/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without
catalytic converters were 2.51 and 412 mg/km, respectively (Schauer et al., 2002). | | Environmental fate | Photolytic. Atkinson (1990) reported a rate constant of 7.0 x 10-12 cm3/molecule?sec for the
reaction of 2,3,4-trimethylpentane and OH radicals in the atmosphere at 298 K. Based on this
reaction rate constant, the estimated lifetime is 20 h (Altshuller, 1991).
Chemical/Physical. Complete combustion in air produces carbon dioxide and water vapor.
2,3,4-Trimethylpentane will not hydrolyze because it does not contain a hydrolyzable functional
group. |
