3-Methyl-1-butene Chemical Properties,Usage,Production

Chemical Properties

Colorless, extremely volatile liquid or gas; disagreeable odor.Soluble in alcohol; insoluble in water.

Physical properties

Colorless, flammable liquid or gas with a disagreeable odor

Uses

3-Methyl-1-butene has been used in asymmetric total synthesis of (?)-Linderol A, a potent inhibitor of melanin biosynthesis of cultured B-16 melanoma cells.

Uses

Organic synthesis, high-octane fuel manufacture.

Definition

ChEBI: An alkene that is but-1-ene carrying a methyl substituent at position 3.

General Description

A colorless volatile liquid with a disagreeable odor. Insoluble in water and less dense than water. Vapors heavier than air. Flash point below 0°F. Used to make other chemicals.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

3-Methyl-1-butene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.

Hazard

Highly flammable, dangerous fire and explosion risk, explosive limits 1.6–9.1%.

Health Hazard

Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.

Safety Profile

Very dangerous fire hazard when exposed to heat, flame, or oxidizers. Explosive in the form of vapor when exposed to heat or flame. To fight fire, use alcohol foam, mist, spray, dry chemical, CO2. When heated to decomposition it emits acrid smoke and irritating fumes. See also 2-METHYL-1 BUTENE.

Source

Schauer et al. (1999) reported 3-methyl-1-butene in a diesel-powered medium-duty truck exhaust at an emission rate of 160 μg/km.
Schauer et al. (2001) measured organic compound emission rates for volatile organic compounds, gas-phase semi-volatile organic compounds, and particle-phase organic compounds from the residential (fireplace) combustion of pine, oak, and eucalyptus. The gas-phase emission rate of 3-methyl-1-butene was 6.9 mg/kg of pine burned. Emission rates of 3-methyl-1-butene were not measured during the combustion of oak and eucalyptus.
California Phase II reformulated gasoline contained 3-methyl-1-butene at a concentration of 380 mg/kg. Gas-phase tailpipe emission rates from gasoline-powered automobiles with and without catalytic converters were 0.35 and 22.5 mg/km, respectively (Schauer et al., 2002).

Environmental Fate

Photolytic. The following rate constants were reported for the reaction of 3-methyl-1-butene and OH radicals in the atmosphere: 3.0 x 10^-11 cm³/molecule?sec (Atkinson et al., 1979); 6.07 to 9.01 x 10-11 cm³/molecule?sec (Atkinson, 1985); 3.18 x 10^-11 cm³/molecule?sec (Atkinson, 1990).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.
