APPLICATION

Used as chromatographic analysis reagent, organic solvent and nylon 66 intermediate. Tetrahydrofuran, also known as oxolane, oxolane, and tetramethylene oxide, is an intermediate in the synthesis of pesticide phenbutyltin.

It can be directly used to make synthetic fibers, synthetic resins, synthetic rubbers, and is also a solvent for many polymer materials, precision tapes and electroplating industries.

In the pharmaceutical industry, it can be used to produce Kebiqing, progesterone, rifamycin and as a pharmaceutical solvent.

-g92D1aUTpWhWpqDRxDQ4w Tetrahydrofuran is suitable for dissolving PVC, polyvinylidene chloride and butyl aniline. It is widely used as a solvent for surface coatings, anti-corrosion coatings, printing inks, tape and film coatings, and as a reaction solvent. It can be used to control aluminum when used in aluminum electroplating. The layer is thick and bright.

THF is treated with hydrogen sulfide to generate tetrahydrothiophenol, which can be used as an odorant (identification additive) in fuel gas. THF can also be used as a surface treatment agent for synthetic leather.
