呋喃
呋喃（英语：furan）是一种含有一个由四个碳原子和一个氧原子的五元芳环的杂环有机物。含有这样的环的化合物通常是呋喃的同系物。
呋喃是一种无色、可燃、易挥发液体，沸点接近于室温。呋喃具有毒性且致癌。它常作为合成其他复杂有机物的起始原料。
呋喃性质与苯相似，可由松木蒸馏得到，可以用来合成多种化合物，如呋喃甲醛（糠醛），呋喃氢化后成四氢呋喃，是一种重要的有机工业原料。

Furan 呋喃
Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen. The class of 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, but is slightly soluble in water. It is toxic and may be carcinogenic in humans. Furan is used as a starting point to other specialty chemicals.
