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 is a food additive, and has FEMA number 270s and ...
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 ]
The name furfural comes from the Latin word furfur, meaning bran, referring to its usual source. Furfural is derived only from dried biomass. Furfural is derived only from dried biomass. In addition to ethanol , acetic acid , and sugar , furfural is one of the oldest known organic chemicals available readily purified from natural precursors.
Related to the production of furfural, MMF can be produced from C-6 sugars hexoses such as glucose and fructose. It is formed via the dehydration of the hexoses and subsequent etherification of hydroxymethylfurfural (HMF). [1] Already in 1936 a batch process was patented for the production of MMF and methyl levulinate. [4]
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 ...
Furfurylamine is an aromatic amine typically formed by the reductive amination of furfural with ammonia. [ 1 ] The pharmaceutical drug furtrethonium , a parasympathomimetic cholinergic , is a trimethyl ammonium derivative of furfurylamine.
5-Chloromethylfurfural is an organic compound with the formula C 4 H 2 O(CH 2 Cl)CHO. It consists of a furan substituted at the 2- and 5-positions with formyl (CHO) and chloromethyl (CH 2 Cl) groups. CMF, as it is called, is obtained by dehydration of fructose and other cellulose derivatives using hydrochloric acid. It is a colourless liquid. [1]
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.
