(fûr`fərəl) or

furfuraldehyde

(fûr'fərăl`dəhīd) [Lat.,=bran], C₄H₃OCHO, viscous, colorless liquid that has a pleasant aromatic odor; upon exposure to air it turns dark brown or black. It boils at about 160&degC;. It is commonly used as a solvent; it is soluble in ethanol and ether and somewhat soluble in water. Furfural is the aldehydealdehyde

A derivative of furan, it is prepared commercially by dehydration of pentose sugars obtained from cornstalks and corncobs, husks of oat and peanut, and other waste products. It is used in the manufacture of pesticides, phenolfurfural resins, and tetrahydrofuran. Tetrahydrofuran is used as a commercial solvent and is converted in starting materials for the preparation of nylonnylon,
synthetic thermoplastic material characterized by strength, elasticity, resistance to abrasion and chemicals, low moisture absorbency, and capacity to be permanently set by heat. After 10 years of research E. I.

Furfural

a yellowish liquid with the odor of fresh rye bread. Furfural has the structural formula

It has a boiling point of 161.7°C and a density of 1.16 g/cm³ at 20°C. Moderately soluble in water, it is readily soluble in alcohol and ether. Its chemical properties are similar to those of benzaldehyde.

Furfural is obtained by the hydrolysis of vegetable matter, such as corn stumps, rice offal, and other materials that contain pentosan. Furfural serves as a raw material in the preparation of furan, tetrahydrofuran, and tetrahydrofuryl alcohol and in the manufacture of furan resins, fungicides, and such pharmaceuticals as Furacin. It is also used in the refining of lubricating oils in the petroleum industry.

furfural

[′fər·fə‚ral] (organic chemistry) C₄H₃OCHO When pure, a colorless liquid, soluble in organic solvents, slightly soluble in water; used as a lube oil-refining solvent, in cellulosic formulations, in making resins, as a weed killer, as a fungicide, and as a chemical intermediate. Also known as 2-furaldehyde; furfuraldehyde; furfurol; furol.
