Furfural is used to make other furan derivatives, such as furoic acid, via oxidation, [30] and furan itself via palladium catalyzed vapor phase decarbonylation. [ 4 ] There is a good market for value added chemicals that can be obtained from furfural.
Methoxymethylfurfural (MMF or 5-methoxymethylfuran-2-carbaldehyde) is an organic compound derived from dehydration of sugars and subsequent etherification with methanol. [1] This colorless liquid is soluble in a wide range of solvents including lower alcohols.
Furan is a colorless, flammable, highly volatile liquid with a boiling point close to room temperature. It is soluble in common organic solvents, including alcohol, ether, and acetone, and is slightly soluble in water. [2] Its odor is "strong, ethereal; chloroform-like". [3] It is toxic and may be carcinogenic in humans.
2,5-Furandicarboxaldehyde is an oxidation product of 5-hydroxymethyl furfural (HMF), which in turn can be prepared from fructose. Alternatively, methods have been developed to convert fructose in one step to 2,5-furandicarboxaldehyde. [ 1 ]
Formation of furan resin from furfuryl alcohol. Components produced by sand casting. Furan resins serve as binders for the casting moulds. Furan resin refers to polymers produced from various furan compounds, [1] of which the most common starting materials are furfuryl alcohol and furfural. In the resin and in the cured polyfurfurol, the furan ...
3-(2-Furoyl)-quinoline-2-carboxaldehyde (FQ) is a fluorogenic amine labeling dye that is not fluorescent itself, but reacts with primary amines to form fluorescent products. [1] It was first reported in 1990. [2] Cyanide, typically provided via KCN or NaCN salts, is a required co-substrate in the fluorogenic reaction. [3]
Hydroxymethylfurfural (HMF), also known as 5-(hydroxymethyl)furfural, is an organic compound formed by the dehydration of reducing sugars. [4] [5] It is a white low-melting solid (although commercial samples are often yellow) which is highly soluble in both water and organic solvents.
Furfuryl alcohol is an organic compound containing a furan substituted with a hydroxymethyl group. It is a colorless liquid, but aged samples appear amber. It possesses a faint odor of burning and a bitter taste. It is miscible with but unstable in water. It is soluble in common organic solvents. [4]
