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 ...
If a 1960s show is rerun today, the content may be edited by nine minutes to make room for the extra advertisements. In the 1950s and 1960s, the average advertisement's length was one minute. [2] Starting in the early 1970s, the average length shrank to 30 seconds. [2] The 15-second commercial began to appear in the late 1980s. [2]
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.
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.
Furan-2-ylmethanethiol (2-furanmethanethiol) is an organic compound containing a furan substituted with a sulfanylmethyl group. It is a clear colourless liquid when pure, but it becomes yellow coloured upon prolonged standing.
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.
This is a disproportionation reaction and produces a 1:1 ratio of 2-furoic acid and furfuryl alcohol (a 50% yield of each). [6] It remains economical because both products have commercial value. The bio-catalytic route involves the microorganism Nocardia corallina .
