Tetrahydrofuran is a kind of important organic synthetic raw material and solvent of excellent performance, particularly applicable to dissolve PVC, polyethylene vinylidene chloride and butyl aniline, widely used for surface coatings, anticorrosive coatings, printing inks, tapes and film coating solvent, and used as reaction solvent, used in electroplating aluminum liquid can be arbitrary control layer thickness and light.THF itself can be condensed again (by cationic ring-opening polymerization) into poly (tetramethylene ether glycol (PTMEG), also known as tetrahydrofuran polyether.PTMEG and toluene diisocyanate (TDI) made resistant, oil resistant, good low temperature performance, high strength of special rubber;With dimethyl terephthalic acid and 1, 4 - butanediol block polyether polyester elastic material.Relative molecular mass of 2000 of PTMEG and methylene double (4 - phenyl) diisocyanate (MDI) made of polyurethane elastic fiber (nylon, SPANDEX fiber), special rubber and coating raw materials of some special purposes.In synthetic solution styrene-butadiene rubber, as an auxiliary random agent, butyl lithium initiation reaction.In organic synthesis, used in the production of tetrahydrothiophene, 1.4 to 2.3 - dichloro - dichloroethane, tetrahydrofuran, e lactone, butyrolactone and pyrrolidone, etc.In the pharmaceutical industry, THF used in synthesis of cough will be clear, doxycycline, progesterone and some hormone medicine.THF thiophenol generated four hydrogen, hydrogen sulfide treatment can make smell of fuel gas agent (identify additive).Tetrahydrofuran can also be used for synthetic leather surface treatment agent.
