Tetrahydrofuran

Tetrahydrofuran (Tetrahydrofuran) is a heterocyclic organic compound, which belongs to the ethers and is a completely hydrogenated product of the aromatic compound furan. It is a colorless, water-miscible, organic liquid with a small viscosity at normal temperature and pressure. Because of its long liquid range, it is a commonly used as a medium-polar aprotic solvent. Its main purpose is to be the precursor of high molecular polymers. 

1. Used as a solvent and raw material for organic synthesis.

2. Used as a chromatographic analytical reagent, organic solvent and intermediate for nylon 66.

3. Tetrahydrofuran (THF) is an important raw material for organic synthesis and an excellent solvent, especially suitable for dissolving PVC, polyvinylidene chloride and butylaniline. It is widely used as a solvent for surface coatings, anti-corrosion coatings, printing inks, magnetic tapes and film coatings, and as a reaction solvent. When used in aluminum plating solutions, it can arbitrarily control the thickness of the aluminum layer and ensure brightness.In organic synthesis, it is used to produce tetrahydrothiophene, 1,2-dichloroethane, 2,3-dichlorotetrahydrofuran, valerolactone, butyrolactone, pyrrolidone, etc.In the pharmaceutical industry, THF is used to synthesize pentoxyverine, rifamycin, progesterone and some hormonal drugs.THF treated with hydrogen sulfide forms tetrahydrothiophenol, which can be used as an odorant (identifier additive) in fuel gas.THF can also be used as a surface treatment agent for synthetic leather.
