Furfural, also known as 2-furfural, is the same substance as furfural. Its scientific name is α-furan formaldehyde, which is a derivative in which the hydrogen atom at the 2-position of furan is replaced by an aldehyde group. Furfural was originally made from rice bran heated with dilute acid, so it is called furfural. Furfural is formed by hydrolysis of pentosan under the action of acid to generate pentose, and then dehydration and cyclization of pentose. The main raw materials for production are agricultural and sideline products such as corn cobs. There are many synthetic methods. 99% Furfural is the most important derivative of the furan ring system. It is chemically active and can produce many derivatives through oxidation, condensation and other reactions. It is widely used in synthetic plastics, medicine, pesticides and other industries.

Application
(1) Chemical Solvent 99% Furfural can well dissolve aromatic hydrocarbons and olefins. Therefore, it is widely used in refining lubricating oil, improving diesel oil quality, refining animal and vegetable oils, and making resins and waxes.
(2) 2-Furaldehyde can also be used as raw material for production and reprocessing, such as production of furfural resin and production of furfural hydrogenation products.
(3) Furfural is also widely used in medicine, antiseptic, bactericide, rust remover and cosmetics industries.
(4) It is used as raw material for organic synthesis, as well as synthetic resin, varnish, pesticide, medicine, rubber and paint.
(5) It is mainly used to prepare furfuryl alcohol, furoic acid, tetrahydrofuran γ- Industrial solvent of pentolactone, pyrrole, tetrahydropyrrole, etc. and used as analytical reagent.
(6) Furfural is a very important organic chemical intermediate, which can be used to prepare pentanediol, acetylpropanol, pentadiene, ketones, methyl tetrahydrofuran, etc.
