Furfural Market Share, Size, Future Demand, and Emerging Trends
Furfural and its by-products have been widely utilized in the plastics, agrochemical, and pharmaceutical sectors. The chemical is a natural precursor to a variety of furan-based chemicals and diluters like furoic acid, dihydropyran, methylfuranfurfuryl alcohol, tetrahydrofuran, and tetrahydrofurfuryl.

Furfural and its by-products have been extensively applied as nematicides and fungicides, gasoline additives, transportation fuels, lubricants, gasoline additives, decolorizing agents, resins, insecticides, jet fuel blend stocks, flavor advancers for food and drinks, quick all-weather repair systems for bomb-dented runways and potholes and also for wood alteration and book preservation.
In the manufacturing procedure, loads of raw material and dilute sulfuric acid are heated under pressure in huge rotary digesters. The furfural made is removed unceasingly with steam, and concentrated by distillation; the concentration, on condensation, splits into two layers. The bottom layer, containing wet furfural, is dehydrated by vacuum distillation to get furfural of least 99% purity.
Furfural is utilized for making plastics, inks, nematicides, adhesives, fertilizers, fungicides, and flavoring compounds. Furfural can be utilized as a solvent or in the formation of tetrahydrofuran (THF), furfuryl alcohol, and levulinic acid (LA). Furfuryl alcohol is made by hydrogenation of furfural. It is a monomer for furan resins, these being utilized primarily as foundry binders. THF is formed by decarbonylation of furfural to furan followed by catalytic hydrogenation.
LA is formed in two reactions, with furfural changing to furfuryl alcohol being the first. Furfuryl alcohol, when simmered in ethyl methyl ketone in the existence of HCl, gives an upsurge to levulinic acid with 94%–97% production. Resins with brilliant thermal, physical, and chemical properties can be formed from furfuryl acid, and they can also be utilized in the manufacture of plastics mixed with fibers. One of the diverse applications of furfural is in distillation technology for C4 and C5 hydrocarbons.
Technological progression in the making process might drastically surge the making yield of this renewable chemical. This will also aid the manufacturers to attain economies of scale for production. The organic compound can also be utilized for producing 5-(hydroxymethyl)furfural, which is a carbon-neutral feedstock for fuel making. In the coming few years, utilization of the chemical as feedstock for biofuel is recognized as a development opportunity for the furfural industry.
