How it is made

Furfural is produced from annually renewable agricultural sources (containing pentosans) such as ... corncobs, cottonseed hulls ... rice hulls ... bagasse ... wood and wood products ... in batch or continuous digestors where the pentosans are hydrolyzed to pentoses and the pentoses subsequently cyclodehydrated to furfural. In all processes, raw material is charged to the digestor and treated with strong inorganic acid. High pressure steam is introduced through the mass and, after attaining operating temperature and pressure, furfural is steam distilled.

May be prepared from pyridine
