The downstream products of furfural

Furfural is a commonly used excellent solvent and an important raw material for organic synthesis. It can be condensed with phenol to produce phenol furfural resin similar to bakelite. Some compounds derived from furfural are also useful chemical products. For example, furfuryl alcohol (furan methanol) is a colorless liquid with a boiling point of 170-171 ° C. It is also an excellent solvent and is a raw material for the manufacture of furfuryl alcohol resin (used for anti-corrosion coatings and glass fiber reinforced plastics); furoic acid (furan formic acid) is white crystals , with a melting point of 133°C, can be used as raw materials for preservatives and plasticizers; tetrahydrofurfuryl alcohol is a colorless liquid with a boiling point of 177°C, and is also an excellent solvent and synthetic raw material. The furan produced from furfural can also be made into succinic dialdehyde through electrolytic reduction, which is the raw material for the production of drug atropine. Many furfural derivatives have strong bactericidal ability. Furfural is mainly used as a solvent, which can selectively extract unsaturated components from petroleum and vegetable oils, and extract aromatic components from lubricating oil and diesel oil. Furfural can replace formaldehyde and condense with phenol to produce phenolic resin.
