                呋喃類|furan
            
      
            
      
                呋喃是一種雜環有機化合物，由一個含四個碳原子和一個氧的五元芳香環組成，含有這種環的化合物也被稱為呋喃類化合物。呋喃是一種無色、易燃、易揮發的液體，沸點接近室溫。它溶于常見的有機溶劑，包括酒精、乙醚和丙酮，微溶于水。它的氣味是“強烈的，飄渺的；像氯仿。”它是有毒的，可能會致癌，呋喃被用作其他特殊化學品的起點。Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen. Chemical compounds containing such rings are also referred to as furans. Furan is a colorless, flammable, highly volatile liquid with a boiling point close to room temperature. It is soluble in common organic solvents, including alcohol, ether, and acetone, and is slightly soluble in water. Its odor is "strong, ethereal; chloroform-like." It is toxic and may be carcinogenic in humans. Furan is used as a starting point to other speciality chemicals.
