Brief Overview
Furfural is a heterocyclic compound consisting of a furan. It is a colourless to amber/reddish-brown liquid with a penetrating odour. It is classified in organic compound and has a chemical formula of C4H3OCHO. Furfural is an essential renewable, non-petroleum based, chemical feedstock which is primarily composed of various agricultural by-products, including oat husks, wheat bran, corncobs, and sawdust. Chemically, furfural is an organic compound belonging to an aldehyde of furan with the odour of almonds.
Manufacturing Process
Furfural is produced annually from renewable agricultural sources such as corn cobs, rice hulls, wood, and wood products where the pentosans are hydrolyzed to pentoses and the pentoses subsequently cyclo-dehydrated 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.
