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.
It is a flavoring ingredient and achieved a generally recognized as safe (GRAS) status in 1995 by the Flavor and Extract Manufacturers Association (FEMA). 2-Furoic acid has a distinct odor described as sweet, oily, herbaceous, and earthy. [3] 2-Furoic acid helps sterilize and pasteurize many foods. It forms in situ from 2-furfural.
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.
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.
2,5-Furandicarboxaldehyde (FDC) is an organic compound with the molecular formula C 4 H 2 O(CHO) 2. It consists of a furan ring with aldehyde groups on the 2 and 5 position. It is therefore classified as a dialdehyde .
Laura Duke, who was recently the detox unit’s supervisor, said the cost put the medication out of reach for all but 1 to 2 percent of the addicts she saw. Detoxing is a first step towards sobriety. To overcome the inevitable pain of withdrawal from opiates without medication—going “cold turkey”—is excruciating.
Natural furan fatty acids are mono- or di-methylated on the furan ring. [1] Furan fatty acids can be found in a variety of plant and animal species. Carboxy-substituted furan fatty acids are known as urofuran acids. Urofuran fatty acids are metabolic products of furan fatty acids and can be detected, for example, in human urine. [2]
