Furfural

Furfural, also known as 2-furaldehyde, its scientific name is α- Furan formaldehyde is a derivative in which the hydrogen atom at position 2 of furan is replaced by aldehyde group. It was originally prepared by co heating rice bran and dilute acid, so it is called furfural.

Furfural is formed by hydrolysis of pentosan to produce pentose under the action of acid, and then dehydration and cyclization of pentose. The main raw materials for production are corncob and other agricultural and sideline products. Chemically, furfural is an organic compound, belonging to furan aldehyde. It has an odor similar to almond oil, and is a liquid that will oxidize and turn pale yellow when exposed to air.

Sugar aldehyde is a basic organic chemical raw material that can not be produced by artificial synthesis in the world at present. It has two double bonds and one aldehyde group on the furan ring. This unique chemical structure can produce many derivatives and other chemical products through oxidation, hydrogenation, chlorination, digestion, condensation and other reactions. It is widely used in resins Liquid crystal casting (automobile, ship, aircraft, various engines, weapons, wind power generation, high-speed railway), synthetic plastics, medicine, essence, spices and other industries.
