外観
無色~ほとんど無色透明液体
化学的特性
Colorless, extremely volatile liquid or
gas; disagreeable odor.Soluble in alcohol; insoluble in water.
物理的性質
Colorless, flammable liquid or gas with a disagreeable odor
使用
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.
定義
ChEBI: An alkene that is but-1-ene carrying a methyl substituent at position 3.
一般的な説明
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.
空気と水の反応
Highly flammable. Insoluble in water.
反応プロフィール
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.
危険性
Highly flammable, dangerous fire and
explosion risk, explosive limits 1.6–9.1%.
健康ハザード
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.
安全性プロファイル
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.
