Furfural
By 1886, furfurol was being called "furfural" (short for "furfuraldehyde") and the correct chemical structure for furfural was being proposed. Furfural is also a specialized chemical solvent.
There is a good market for value added chemicals that can be obtained from furfural.

2-Furonitrile
Synthesis
Industrial synthesis is based on the vapor phase ammoxidation of furfural with ammonia over bismuth molybdate catalyst at 440-480 °C. From furfural aldoxime (with thionyl chloride-benzotriazole, triphenylphosphine-iodine reagents, or heating in DMSO) and furoic acid amide (flash vacuum

Furan
History
The name "furan" comes from the Latin furfur, which means bran (furfural is produced from bran). :
In the laboratory, furan can be obtained from furfural by oxidation to 2-furoic acid, followed by decarboxylation.

Quantitative measuring method for 5-hydroxymethyl furfural in shengmai ...
The invention relates to a quantitative measuring method for 5-hydroxymethyl furfural in a shengmai injection. The 5-hydroxymethyl furfural has a certain toxic side effect to a human body, thereby the quality of the shengmai injection can be improved by controlling the content of the 5-hydroxymethyl furfural. The method for measuring the content of the 5-hydroxymethyl furfural comprises the ...
