Tetrahydrofuran is an important organic synthetic raw material and a solvent with excellent performance. It is especially suitable for dissolving PVC, polyvinylidene chloride and butyl aniline. It is widely used as a solvent for surface coatings, anticorrosive coatings, printing inks, magnetic tapes and film coatings. As a reaction solvent, it can arbitrarily control the thickness of the aluminum layer and bright when it is used for electroplating aluminum liquid. Tetrahydrofuran itself can be polycondensed (by cation-induced ring-opening repolymerization) to form polytetramethylene ether glycol (PTMEG), also known as tetrahydrofuran homopolyether.
PTMEG and toluene diisocyanate (TDI) are made into special rubbers with wear resistance, oil resistance, low temperature performance and high strength; and block polyether polyester elasticity with dimethyl terephthalate and 1,4-butanediol material. PTMEG with a relative molecular weight of 2000 and p-methylene bis (4-phenyl) diisocyanate (MDI) are used as raw materials for polyurethane elastic fibers (spandex, or SPANDEX fibers), special rubbers, and some special-purpose coatings. In organic synthesis, it is used to produce tetrahydrothiophene, 1.2-dichloroethane, 2.3-dichlorotetrahydrofuran, valerolactone, butyrolactone and pyrrolidone. In the pharmaceutical industry, THF is used to synthesize cetrine, rifamycin, progesterone and some hormone drugs. THF is treated with hydrogen sulfide to produce tetrahydrothiophenol, which can be used as odorant (identification additive) in fuel gas. THF can also be used as a surface treatment agent for synthetic leather.
