The use of tetrahydrofuran

THF is an important raw material for organic synthesis and is a solvent with excellent properties, especially suitable for dissolving PVC, polyvinylidene chloride and butyl aniline. It is widely used as a solvent for surface coatings, anticorrosive coatings, printing ink, tape and film coatings, and as a reaction solvent. When used for electroplating aluminum liquid, the thickness of aluminum layer can be controlled arbitrarily and bright.

THF itself can be polycondensation (by cationic ring-opening repolymerization) into polytetramethylene ether diol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG and toluene diisocyanate (TDI) made of wear resistance, oil resistance, low temperature performance, high strength of special rubber; Block polyether polyester elastic Chemicalbook material was prepared with dimethyl terephthalate and 1, 4-butanediol.

PTMEG with relative molecular weight of 2000 and p-methylene bis (4-phenyl) diisocyanate (MDI) to make polyurethane elastic fiber (SPANDEX fiber), special rubber and some special purpose coating raw materials.

In organic synthesis, it is used to produce tetrahydrothiophene, 1.4- dichloroethane, 2.3- dichlorotetrahydrofuran, valerolactone, butyl lactone and pyrrolidone. In the pharmaceutical industry, THF is used in the synthesis of coughbexil, rifumycin, progesterone and some hormone drugs.

THF is treated with hydrogen sulfide to produce tetrahydrothiophenol, which can be used as odor agent in fuel gas. THF can also be used as a surface treatment agent for synthetic leather.
