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 has an aldehyde group attached to the 2-position of furan. It is a product of the dehydration of sugars, as occurs in a variety of agricultural byproducts, including corncobs, oat, wheat bran, and sawdust.
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 ...
The synthesis of novel biomass-based vinyl polymers from 5-methoxymethyl furfural as the starting material was described by Yoshida. [7] HMF and MMF are also key molecules into the conversion of liquid biofuels. HMF and MMF can be converted to a wide range of mono- and dialkoxymethyl ethers. [8]
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.
5-Methylfurfuryl alcohol is an organic compound with the formula C 6 H 8 O 2.It is one of many volatile compounds present in Nicotiana tabacum, [3] and is formed from the reduction of 5-methylfurfural, [4] a compound formed from the reduction of 5-bromo-or 5-chloromethylfurfural. [5]
It is a colourless liquid. [1] It can be reduced to give 5-methylfurfural, and can be hydrolyzed to give hydroxymethylfurfural. Typical nitrile gloves do not protect against CMF. The compound, even when handled as a solid, can absorb through gloves and stain the skin a dark brown black color.
Various early 20th Century embalming fluids. Embalming chemicals are a variety of preservatives, sanitising and disinfectant agents, and additives used in modern embalming to temporarily prevent decomposition and restore a natural appearance for viewing a body after death.
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.
