This is a natural process that is the basis of the commercial production of furfural.

In the first half of the 19th century, chemists such as Johann W. Döbereiner at the University of Jena (Germany) and John Stenhouse at Glasgow University discovered furfural in the distillation products of various biomaterials. 
FURFURAL did not become an industrial product until Quaker Oats (Chicago) began to produce FURFURAL on a large scale from oat hulls.

FURFURAL, one of the earliest sustainable chemical feedstocks, is used to synthesize a wide range of industrial chemicals, including solvents, resins, plastics, and furan derivatives. 
As the hazard information table shows, FURFURAL must be handled with an abundance of caution.

FURFURAL is one of several five-carbon oxygenated hydrocarbons that make up the aroma of canned pumpkin you might use to make your Thanksgiving pumpkin pie.

Uses of FURFURAL:
Now that we know what the structure of furfural looks like and how FURFURAL's produced, let's talk about a couple of the more important applications FURFURAL can be utilized for. 
If we take furfural and convert the aldehyde to an alcohol in what's called a reduction reaction, we get furfuryl alcohol (abbreviated FA). 
FA is used in the manufacture of things like cement, adhesives, castings, and coatings.

Uses and Occurrence of FURFURAL:
FURFURAL is found in many foods: coffee (55–255 mg/kg) and whole grain bread (26 mg/kg).
FURFURAL is an important renewable, non-petroleum based, chemical feedstock. 
FURFURAL can be converted into a variety of solvents, polymers, fuels and other useful chemicals by a range of catalytic reduction.

Hydrogenation of furfural provides furfuryl alcohol (FA), which is used to produce Furan resins, which are exploited in thermoset polymer matrix composites, cements, adhesives, casting resins and coatings.
Further hydrogenation of furfuryl alcohol leads to tetrahydrofurfuryl alcohol (THFA), which is used as a solvent in agricultural formulations and as an adjuvant to help herbicides penetrate the leaf structure.

In another application as a feedstock, palladium-catalyzed decarbonylation on furfural manufactures industrially furan.
Another important solvent made from furfural is methyltetrahydrofuran. 
FURFURAL is used to make other furan derivatives, such as furoic acid, via oxidation, and furan itself via palladium catalyzed vapor phase decarbonylation. 

FURFURAL is also a specialized chemical solvent.
There is a good market for value added chemicals that can be obtained from furfural.

Function and Uses of FURFURAL:
Large quantities of FURFURAL are used in solvent extraction in the petroleum refining industry. 
FURFURAL is also used as a solvent (for nitrated cotton, cellulose acetate and gums), to accelerate vulcanization, as an ingredient of phenolic resins (Durite), as an intermediate in the synthesis of furan derivatives, as a weed killer, as a fungicide and as a flavouring agent.

FURFURAL has been identified in 150 foods, including fruits, vegetables, beverages, bread and bread products. 
The highest reported concentrations were found in wheat bread (0.8–14 ppm) [mg/kg], cognac (0.6–33 ppm), rum (22 ppm), malt whisky (10–37 ppm), port wine (2–34 ppm) and coffee (55–255 ppm). 

The concentrations of FURFURAL in juices were 0.01–4.93 ppm.
FURFURAL is an ingredient contained in many fragrances and flavours. 

FURFURAL may be found in fragrances used in decorative cosmetics, fine fragrances, shampoos, toilet soaps and other toiletries, in flavours of oral care products as well as in non-cosmetic products such as household cleaners and detergents.
FURFURAL in the in the fragrance compound is reported to be 0.036% or less. 

FURFURAL in Practice:
FURFURAL has an aromatic odour reminiscent of almonds. 
This biomass-based chemical is a hetero-aromatic aldehyde with exceptional physical properties. 

Production of FURFURAL:
FURFURAL may be obtained by the acid catalyzed dehydration of 5-carbon sugars (pentoses), particularly xylose.

C5H10O5 → C5H4O2 + 3 H2O

These sugars may be obtained from pentosans obtained from hemicellulose present in lignocellulosic biomass.
Between 3% and 10% of the mass of crop residue feedstocks can be recovered as furfural, depending on the type of feedstock. 

FURFURAL and water evaporate together from the reaction mixture, and separate upon condensation. 
The global production capacity is about 800,000 tons as of 2012. 

China is the biggest supplier of furfural, and accounts for the greater part of global capacity. 
The other two major commercial producers are Illovo Sugar in the Republic of South Africa and Central Romana in the Dominican Republic.
In the laboratory, furfural can be synthesized from plant material by heating with sulfuric acid or other acids.

With the purpose to avoid toxic effluents, an effort to substitute sulfuric acid with easily separable and reusable solid acid catalysts has been studied around the world.
The formation and extraction of xylose and subsequently furfural can be favored over the extraction of other sugars with varied conditions, such as acid concentration, temperature, and time.
In industrial production, some lignocellulosic residue remains after the removal of the furfural.

This residue is dried and burned to provide steam for the operation of the furfural plant. 
Newer and more energy efficient plants have excess residue, which is or can be used for co-generation of electricity, cattle feed, activated carbon, mulch/fertiliser, etc.

We mentioned previously that furfural was a renewable chemical feedstock. 
The reason this is the case actually stems from how FURFURAL's made. 

FURFURAL can be produced on large industrial scales by taking plant mass and treating FURFURAL with an acid. 
When this happens, the 5-carbon sugar molecules undergo a dehydration (loss of water) reaction to give furfural.

Depending on the type of plant matter that's used, anywhere between 3% and 10% of the original plant mass can be recovered as furfural. 
Obviously, plants are constantly growing and being produced, that's why furfural is considered a 'green' or renewable source of chemical feedstocks. 
FURFURAL could potentially represent an important source of organic compounds once petroleum resources start to dry up.

History of FURFURAL:
FURFURAL was first isolated in 1821 (published in 1832) by the German chemist Johann Wolfgang Döbereiner, who produced a small sample as a byproduct of formic acid synthesis.
In 1840, the Scottish chemist John Stenhouse found that the same chemical could be produced by distilling a wide variety of crop materials, including corn, oats, bran, and sawdust, with aqueous sulfuric acid; he also determined furfural's empirical formula (C5H4O2).
George Fownes named this oil "furfurol" in 1845 (from furfur (bran), and oleum (oil)).

In 1848, the French chemist Auguste Cahours determined that furfural was an aldehyde.
Determining the structure of furfural required some time: the furfural molecule contains a cyclic ether (furan), which tends to break open when FURFURAL's treated with harsh reagents. 
In 1870, German chemist Adolf von Baeyer speculated (correctly) about the structure of the chemically similar compounds furan and 2-furoic acid.

By 1886, furfurol was being called "furfural" (short for "furfuraldehyde") and the correct chemical structure for furfural was being proposed.
By 1887, the German chemist Willy Marckwald had inferred that some derivatives of furfural contained a furan nucleus.
In 1901, the German chemist Carl Harries determined furan's structure by synthesizing FURFURAL from succindialdehyde, thereby also confirming furfural's proposed structure.

FURFURAL remained relatively obscure until 1922, when the Quaker Oats Company began mass-producing FURFURAL from oat hulls.
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.

Structure of FURFURAL:
Let's get started by looking at the structure of furfural. 
FURFURAL is an aldehyde of furan and is a yellow oily liquid in pure form, but tends to turn brown upon prolonged exposure to air and moisture. 

An aldehyde is an organic functional group that has a carbonyl group (carbon-oxygen double bond) attached to a hydrogen and some other carbon-based side chain. 
Furan is an aromatic five-membered ring that has an oxygen atom embedded within the ring system. 
Notice that the aldehyde portion of the molecule is bonded to the carbon that's directly adjacent to the oxygen of the furan ring.

Due to the polar nature of FURFURAL, FURFURAL will dissolve quite readily and form solutions with a variety of polar organic solvents like methanol, ethanol, chloroform, and dimethyl sulfoxide (DMSO). 
FURFURAL will not, however, dissolve in water and particularly non-polar solvents like hexane.

Properties of FURFURAL:
FURFURAL dissolves readily in most polar organic solvents, but FURFURAL is only slightly soluble in either water or alkanes.
FURFURAL participates in the same kinds of reactions as other aldehydes and other aromatic compounds. 

FURFURAL exhibits less aromatic character than benzene, as can be seen from the fact that furfural is readily hydrogenated to tetrahydrofurfuryl alcohol. 
When FURFURAL is heated in the presence of acids, furfural irreversibly polymerizes, acting as a thermosetting polymer.

Safety of FURFURAL:
FURFURAL is carcinogenic in lab animals and mutagenic in single cell organisms, but there is no data on human subjects. 
FURFURAL is classified in IARC Group 3 due to the lack of data on humans and too few tests on animals to satisfy Group 2A/2B criteria. 
FURFURAL is hepatotoxic.

The median lethal dose is high 650–900 mg/kg (oral, dogs), consistent with FURFURAL pervasiveness in foods.
The Occupational Safety and Health Administration has set a permissible exposure limit for furfural at 5 ppm over an eight-hour time-weighted average (TWA), and also designates furfural as a risk for skin absorption.
