Furfural is an organic compound with the formula C 4 H 3 OCHO. It is a colorless liquid, although commercial samples are often brown. It is a colorless liquid, although commercial samples are often brown.
Furfuryl alcohol is manufactured industrially by hydrogenation of furfural, which is itself typically produced from waste bio-mass such as corncobs or sugar cane bagasse. As such furfuryl alcohol may be considered a green chemical. [5] One-pot systems have been investigated to produce furfuryl alcohol directly from xylose using solid acid ...
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.
The name "furan" comes from the Latin furfur, which means bran [5] (furfural is produced from bran). The first furan derivative to be described was 2-furoic acid, by Carl Wilhelm Scheele in 1780. Another important derivative, furfural, was reported by Johann Wolfgang Döbereiner in 1831 and characterised nine years later by John Stenhouse.
5-Methylfurfural is an organic compound with the formula C 6 H 6 O 2.An aldehyde that is derived through various extractions and reductions from cellulose products, [5] [6] it has applications as a synthetic intermediate [7] relevant to the fields of medicine, agriculture and cosmetics. [8]
These substances include small amounts of chemicals such as methanol and other alcohols (known as fusel alcohols), acetone, acetaldehyde, esters, tannins, and aldehydes (e.g. furfural). Congeners are responsible for most of the taste and aroma of distilled alcoholic beverages, and contribute to the taste of non-distilled drinks. [1]
Example of furfurylated pine wood with a loading level of 30–35%) Furfurylated wood is the end product of treating wood with furfuryl alcohol.This chemical process is also called furfurylation.
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 rings are not connected by conjugation. The resins are generally used as binders for sand castings.
