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 ...
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 ]
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.
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]
It remains economical because both products have commercial value. The bio-catalytic route involves the microorganism Nocardia corallina . This produces 2-furoic acid in higher yields: 98% from 2-furfuryl alcohol and 88% from 2-furfural, [ 7 ] but has yet to be commercialised.
2,5-BHMF may be obtained from the reduction of the formyl group of 5-hydroxymethylfurfural (HMF). HMF is the product of acid-catalyzed dehydration of fructose.Fructose is both an isomer of and a derivative of glucose, which can be derived from the hydrolysis of cellulose.
In the furfurylation process, the walls of woody cells are initially swollen with the furfuryl-alcohol-based solution. Due to its polarity and size, furfuryl alcohol penetrates the cell wall. [3] The polymerization of furfuryl alcohol in wood is a complex reaction whose processes are not fully understood.
More recently, furfuryl alcohol has been used for the same purpose. [9] 2,5-Dimethylfuran has also been proposed as an internal standard for NMR spectroscopy. 2,5-Dimethylfuran has singlets in its 1 H NMR spectrum at δ 2.2 and 5.8; the singlets give reliable integrations, while the positions of the peaks do not interfere with many analytes ...
