3-METHYLHEXANE Chemical Properties,Usage,Production

Chemical Properties

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).

Uses

3-Methylhexane can be used as a model alkane to study:

  • Cu-catalyzed hydrocarboxylation of simple alkanes to corresponding branched monocarboxylic acids in aqueous medium at low-temperature.
  • Au-catalyzed oxygenation of alkanes with H2O2 in acetonitrile.
  • FeCI3 catalyzed photooxygenation of simple alkanes to corresponding alcohols in presence of atmospheric O2.

Uses

Organic synthesis, oil extender solvent.

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.

Hazard

Flammable, dangerous fire risk.

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.]
