化学的特性
2-Methylfuran is a cyclic diene possessing ether-like properties. It is highly reactive with many inorganic and organic compounds yielding a variety of new derivatives which await exploration for the development of commercial applications.
天然物の起源
Reported found in cooked beef, bread, butter, chicken, cocoa, coffee, currant, mint, tea and tomato.
使用
2-Methylfuran is a volatile organic compound (VOCs) used as a potential non-intrusive tool for screening of lung cancer.
一般的な説明
A clear colorless liquid with an ethereal odor. Flash point -22°F. Less dense than water and insoluble in water. Hence floats on water. Vapors heavier than air.
空気と水の反応
Highly flammable. Insoluble in water.
反応プロフィール
2-Methylfuran is incompatible with strong acids and strong bases. May react vigorously with oxidizing materials .
危険性
Highly flammable, dangerous fire andexplosion risk. Irritant.
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
Poison by ingestion.
Moderately toxic by inhalation. An eye
irritant. Mutation data reported. Very
dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing
materials. To fight fire, use CO2, dry
chemical. When heated to decomposition it
emits acrid smoke and irritating fumes.
純化方法
Wash it with acidified saturated ferrous sulfate solution (to remove peroxides), separate, dry with CaSO4 or CaCl2, and fractionally distil it from KOH immediately before use. To reduce the possibility of spontaneous polymerisation, addition of about one-third of its volume of heavy mineral oil to 2-methylfuran prior to distillation has been recommended.
