MUSCAT CHEMICAL TAG::
Furfural is one of the furan derivatives formed from the hemicellulosic portion of lignocellulosics. ... Furfural is formed by dehydrating five-carbon sugars such as xylose and arabinose that can be obtained from the hemicellulose fraction of lignocellulosic biomass.
It is used as a solvent for nitrated cotton, cellulose acetate and gums; for accelerating vulcanization; in the synthesis of furan derivatives.

Furfural is used for making inks, plastics, antacids, adhesives, nematicides, fungicides, fertilizers, and flavoring compounds . Furfural can be used as a solvent or in the making of furfuryl alcohol, tetrahydrofuran (THF), and levulinic acid (LA). Furfuryl alcohol is prepared by hydrogenation of furfural.
