CLEAR COLOURLESS LIQUID | [Physical properties]
Clear, colorless flammable liquid with an unpleasant hydrocarbon odor. | [Definition]
ChEBI: 2-methyl-1-pentene is an alkene that is pent-1-ene carrying a methyl group at position 2. It has a role as a human metabolite. It is an alkene and a volatile organic compound. It derives from a hydride of a pentane. | [Source]
California Phase II reformulated gasoline contained 2-methyl-1-pentene at a
concentration of 1.25 g/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles
with and without catalytic converters were 0.23 and 26.6 mg/km, respectively (Schauer et al.,
2002). | [Environmental Fate]
Photolytic. The reported reaction rate constants for the reaction of 2-methyl-1-pentene with OH
radicals and ozone in the atmosphere are 1.05 x 10-17 and 6.26 x 10-11 cm3/molecule?sec,
respectively (Atkinson and Carter, 1984; Atkinson, 1985).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water. | [Purification Methods]
Water is removed, and formation of peroxides is prevented by several vacuum distillations of 2-methyl-1-pentene from sodium. It is stored with sodium-potassium alloy. [Beilstein 1 IV 841.] |
