Furan

 

(furfuran), a heterocyclic compound; a colorless liquid, with a chloroform odor and a boiling point of 31.33°C. A large group of organic compounds, many of which are of practical

value, are derived from furan, for example, furfural, tetrahydrofuran, and 2-methylfuran. Furan is obtained primarily from furfural. It is an intermediate product in the synthesis of tetrahydrofuran; it is also used in the preparation of pyrrole, by a reaction with NH3 in the presence of Al2O3.
