Furfural (C 4 H 3 O-CHO), also called 2-furaldehyde, best known member of the furan family and the source of the other technically important furans. Publication History. An overview of the applications of furfural and its derivatives. Furan is a colourless, volatile organic compound that is used in some chemical manufacturing industries and may also be found in low levels in some foods, most notably in foods that undergo thermal treatment such as canning or jarring. The top countries of supplier is China, from which the percentage of furan uses … Furan definition is - a cyclic flammable liquid compound C4H4O that is obtained from wood oils of pines or made synthetically and is used especially in organic synthesis; also : any of various derivatives of furan. It acts as an industrial solvent for making polyvinyl chloride (PVC), the plastic that the majority of indoor plumbing is made out of, and it also dissolves PVC, and therefore is a primary ingredient in PVC adhesives. Furan definition, a colorless, liquid, unsaturated, five-membered heterocyclic compound, C4H4O, obtained from furfural: used chiefly in organic synthesis. Considerable attention has been focused on the synthesis of furan derivatives and screening them for pharmacological activity. Tetrahydrofuran is a versatile solvent, which is one of its main uses.

Chem. Industrial Uses of Furans.
Furfural is an aldehyde of furan and is a yellow oily liquid in pure form, but tends to turn brown upon prolonged exposure to air and moisture. Pyrrole is a 5-membered aromatic heterocycle, like furan and thiophene.Unlike furan and thiophene, it has a dipole in which the positive end lies on the side of the heteroatom, with a dipole moment of 1.58 D.
