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. Chemically, furfural is an organic compound belonging to furan aldehyde, which has an odor similar to almond oil, and is a liquid that oxidizes and changes color to light yellow when exposed to air. Fufural is a basic organic chemical raw material that cannot be produced by artificial synthesis in the world at present. It has two double bonds on the furan ring and an aldehyde group. This unique chemical structure can be synthesized by oxidation, hydrogenation, chlorine It is widely used in resin, liquid crystal casting (automobiles, ships, aircraft, various engines, weapons, wind power, high-speed rail), synthetic plastics, medicine, Flavor, fragrance and other industries.
