CLEAR COLOURLESS LIQUID | [Physical properties]
Clear, colorless liquid with an odor similar to hexane. An odor threshold concentration of 840
ppbv was reported by Nagata and Takeuchi (1990). | [Definition]
ChEBI: 3-methylhexane is an alkane that is hexane substituted by a methyl group at position 3. It has a role as a human metabolite. It is an alkane and a volatile organic compound. | [Source]
Schauer et al. (1999) reported 3-methylhexane in a diesel-powered medium-duty truck
exhaust at an emission rate of 310 μg/km.
California Phase II reformulated gasoline contained 3-methylhexane at a concentration of 16.2
g/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without
catalytic converters were 2.95 and 415 mg/km, respectively (Schauer et al., 2002). | [Environmental Fate]
Photolytic. Based on a reported photooxidation reaction rate constant of 7.20 x 10-12
cm3/molecule?sec with OH radicals, the half-life of 3-methylhexane is 20 h (Altshuller, 1990).
Chemical/Physical. Complete combustion in air produces carbon dioxide and water vapor. 3-
Methylhexane will not hydrolyze because it does not contain a hydrolyzable functional group. | [Purification Methods]
Purify it as for 2-methylhexene. [Beilstein 1 IV 399.] | [Toxics Screening Level]
The initial threshold screening level (lTSL) for 3-methylhexane is 3,500 μg/m3 based on an 8 hr. averaging time. |
