3-METHYLPENTANE Chemical Properties,Uses,Production
Chemical Properties
3-Methylpentane, C6H14, is a colorless, flammable liquid with specific gravity 0.664. It occurs in petroleum and natural gas, and may be released to the environment in evaporative losses, wastewater, spills, and combustion exhaust.
Physical properties
Clear, colorless, flammable liquid with an odor similar to hexane, heptane, and similar aliphatic hydrocarbons. An odor threshold concentration of 8.9 ppmv was reported by Nagata and Takeuchi (1990).
Uses
3-Methylpentane is a component of three typical commercial hexanes, obtained from the fractionation of natural gas liquids, a refinery operation involving hydrogenation, and a stream meeting polymerization. Other than for fuel, it is used in extraction of oil from seeds and as a solvent and reaction medium in the manufacture of polyolefins, synthetic rubbers, and some pharmaceuticals.
Hazard
Flammable, dangerous fire risk.
Safety Profile
May have narcotic or anesthetic properties. A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. Explosive in the form of vapor when exposed to heat or flame. To fight fire, use foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.
Environmental Fate
Photolytic. The following rate constants were reported for the reaction of 3-methylpentane and
OH radicals in the atmosphere: 4.30 x 10-9 cm3/molecule?sec at 300 K (Darnall et al., 1976); 6.8 x
10-12 cm3/molecule?sec at 305 K (Darnall et al., 1978); 5.7 x 10-12 cm3/molecule?sec (Altshuller,
1991).
Chemical/Physical. Complete combustion in air produces carbon dioxide and water vapor. 3-
Methylpentane will not hydrolyze because it does not contain a hydrolyzable functional group.
Purification Methods
Purify it by azeotropic distillation with MeOH, as for 2-methylpentane. Purify it for ultraviolet spectroscopy by passing it through columns of silica gel or alumina activated by heating for 8hours at 210o under a stream of nitrogen. Alternatively treat it with conc (or fuming) H2SO4, then wash it with water, aqueous 5% NaOH, water again, then dry (CaCl2, then sodium), and distil it through a long, glass helices-packed, column.
