Furfural CAS#98-01-1

Furfural is an essential renewable, non-petroleum based, chemical feedstock which is primarily composed of various agricultural byproducts, including oat husks, wheat bran, corncobs, and sawdust. Chemically, furfural is an organic compound belonging to an aldehyde of furan with the odor of almonds. It is typically produced for industrial purposes, which can be used as a selective solvent in the process of refining lubricating oils and used in the manufacture of transportation fuels to improve the characteristics of diesel fuel and catalytic cracker recycle stocks. Besides, furfural is applied widely for producing resin-bonded abrasive wheels and purifying butadiene needed for the manufacture of synthetic rubber. It is also used to make other furan chemicals, such as furoic acid and furan itself. Other products of furfural include weed killer, fungicide, other solvents and etc.

Product Application of Furfural CAS#98-01-1

Commercially, furfural is produced through hydrolysis of pentosan in agricultural byproducts (e.g., crop wastes). It has a diverse applications which include as a solvent in various manufacturing industries (e.g., petroleum and automotive products), accelerant for vulcanization of rubber, raw material for manufacturing furan derivatives (e.g., tetrahydrofurfuryl alcohol) and synthetic resins, wetting agent, flavoring ingredient for foods (e.g., roasted coffee), fragrance in consumer and personal care products (e.g., fragrance cream, bath products, toiletries), and pesticides for controlling unwanted microorganisms, fungi, weeds, insects, and nematodes. The application methods for pesticidal use include drip irritation, spray boom, sprinkler, and low-pressure back-pack spray.
