Furfural is produced in a digester under high-pressure steam, from where it is recovered by steam distillation, followed by water-furfural separation and purification. The scheme illustrates all consecutive steps in the conversion of sugar cane bagasse into Furfural. In the first step pentosans are hydrolyzed by strong mineral acids to monomeric C5-sugars. Subsequent cyclodehydration of the pentoses yields Furfural.
