Furfural is a kind of organic matter, used as raw material for organic synthesis, also used in synthetic resin, varnish, pesticide, medicine, rubber and coatings;  

Mainly used as an industrial solvent, for the production of furfuryl alcohol, furoic acid, tetrahydrofuran, γ -valerolactone, pyrrole, tetrahydropyrrole, etc.;  

Used as an analytical reagent;  Used for tanning leather.  It should be stored in a cool, ventilated warehouse, away from light, prevent sun exposure, away from fire. Furfural is the raw material for the preparation of many drugs and industrial products. Furan can be reduced by electrolysis and can also be made into succinaldehyde, which is the raw material for the production of atropine.  Some derivatives of furfural have strong bactericidal ability and broad bacteriostatic spectrum.  For example, furfural through 5-nitrofurfural, and then with hydrochloric acid urea condensation to obtain furacillin, is a disinfectant antiseptic.  Chinese furfuraldehyde - YuanfarChemicals

Furfural is the raw material of furan acrylic acid, furosamine fumaric acid, adiponic acid, furfuryl alcohol and other intermediates. It is widely used in the synthesis of fine chemicals such as medicine, pesticide, veterinary drug, dye, perfume, rubber auxiliaries, preservatives and so on.  The largest consumption of furfural is as a solvent and raw material for synthetic resins.  

In the synthetic resin, can produce furan resin, furfural resin and furfurone resin.  Furan resin is also called furfuryl alcohol resin. Furfural is hydrogenated to furfuryl alcohol under high pressure, and furfuryl alcohol is polymerized to furfuryl alcohol resin.  This resin has strong alkali resistance, high heat resistance and water resistance, can be used as caulking resin cement, anti-corrosion lining, binder.  Furfural can be used as a solvent to selectively extract unsaturated components from petroleum and vegetable oils.  

Extraction of aromatic components in lubricating oil and diesel oil with furfural.  Improve the quality of these products.  In synthetic rubber production, butadiene and isoprene were purified by furfural extraction.  Furfural can irritate the skin and mucous membranes, and the highest permissible concentration in the air is 5ppm.  The oral LD50 of rats was 127mg/kg.  ;  Spices for food as permitted in GB 2760-96;  Extraction solvent.  It is mainly used to prepare various kinds of heat-processed essence, such as bread, butterscotch, coffee essence, etc.  ;  

Furfural is an important organic chemical raw material, which can be used to make maleic anhydride, glycolic acid, furfuryl alcohol, tetrahydrofuran, and can also be used to synthesize furfural resin, furan resin, rubber vulcanization accelerator, rubber and plastic aging agent, preservative and so on.  Mainly used in medicine, pesticides, veterinary drugs and food line.
