Chemische Eigenschaften
Colorless, extremely volatile liquid or
gas; disagreeable odor.Soluble in alcohol; insoluble in water.
Physikalische Eigenschaften
Colorless, flammable liquid or gas with a disagreeable odor
Verwenden
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.
Definition
ChEBI: An alkene that is but-1-ene carrying a methyl substituent at position 3.
Allgemeine Beschreibung
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 Reaktionen
Highly flammable. Insoluble in water.
Reaktivität anzeigen
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.
Sicherheitsprofil
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.
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 cm
3/molecule?sec (Atkinson et al., 1979); 6.07 to 9.01 x
10-11 cm
3/molecule?sec (Atkinson, 1985); 3.18 x 10
-11 cm
3/molecule?sec (Atkinson, 1990).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water.
