Main application of Furfural 98.5%min CAS 98-01-1
- It is used as raw material for organic synthesis, as well as synthetic resin, varnish, pesticide, medicine, rubber and coating, etc;
- It is mainly used as industrial solvent for preparing furfuryl alcohol, furoic acid, tetrahydrofuran γ- Pentalactone, pyrrole, tetrahydropyrrole, etc;
- Used as an analytical reagent for tanning leather. It should be stored in a cool and ventilated warehouse, away from light, sun exposure and fire source.
- Furfural is the raw material for preparing many drugs and industrial products. Furan can also be made into Succinic aldehyde by electrolytic reduction, which is the raw material for the production of drug atropine. Some derivatives of furfural have strong bactericidal ability and broad antibacterial spectrum. For example, furfural is condensed with 5-nitrofurfural and aminourea hydrochloride to obtain furacilin, which is a disinfectant and antiseptic.
- Furfural is the raw material of furan, acrylic acid, furfuramine, fumaric acid, adipic acid, furfuryl alcohol and other intermediates. It is widely used in the synthesis of fine chemicals such as medicine, pesticides, veterinary drugs, dyes, spices, rubber additives, preservatives and so on. Furfural is the most consumed field as solvent and raw material of synthetic resin.
- In terms of synthetic resin, it can produce furan resin, furfural resin and furfural ketone resin. Furan resin is also called furfural alcohol resin. Furfural is hydrogenated under high pressure to produce furfural alcohol, which is polymerized to obtain furfural alcohol resin. This resin has strong alkali resistance, high heat resistance and water resistance. It can be used as caulking resin, cement, anti-corrosion lining and binder. Furfural, as a solvent, can selectively extract unsaturated components from petroleum and vegetable oil.
- The aromatic components in lubricating oil and diesel oil were extracted with furfural. Improve the quality of these products. In the production of synthetic rubber, butadiene and isoprene were extracted and purified with furfural. Furfural can stimulate skin and mucous membrane, and the maximum allowable concentration in the air is 5ppm. The oral LD50 of rats was 127mg / kg. It is a food flavor allowed in GB 2760-96; Extraction solvent. It is mainly used for preparing all kinds of flavors such as bread, butter, hard candy, coffee and so on.
