Furfural remained relatively obscure until 1922, [6] when the Quaker Oats Company began mass-producing it from oat hulls. [18] Today, furfural is still produced from agricultural byproducts like sugarcane bagasse and corn cobs. The main countries producing furfural today are the Dominican Republic, South Africa and China.
However, the high cost of the two-stage impregnation prevented the production of furfurylated wood at market-demanded prices. [7] In 1997, Wood Polymer Technologies ASA in Norway was founded in an attempt to build a pilot plant for a single stage production process. [8] From 2000 onwards, furfurylated wood has been marketed in the US and Europe.

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]
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.

A future market trend can only be determined in hindsight, since at any time prices in the future are not known. Past trends are identified by drawing lines, known as trendlines, that connect price action making higher highs and higher lows for an uptrend, or lower lows and lower highs for a downtrend.
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.
