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. | [Hazardous Substances Data]

| Hazard Information | Back Directory | [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. | [Reactivity Profile]
3-METHYL-1-BUTENE(563-45-1) 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. | [Air & Water Reactions]
Highly flammable. Insoluble in water. | [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. | [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 | [Definition]
ChEBI: An alkene that is but-1-ene carrying a methyl substituent at position 3. | [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. |
