Used as solvent and raw material for organic synthesis.
Used as chromatographic analysis reagent, organic solvent and nylon 66 intermediate. Also used in the production of adipdinitrile, adipadipic acid, adipdiamine, succinic acid, butanediol, gamma-butylactone, etc., in the pharmaceutical industry, can be used for the production of cough bixin, progesterone, rifumycin and used as a pharmaceutical solvent.
Hexamethylcyclotrisiloxane exporter 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, The thickness and brightness of aluminum layer can be controlled arbitrarily when electroplating aluminum liquid. Hexamethylcyclotrisiloxane exporter itself can be condensed again (by cationic ring-opening polymerization) into poly (tetramethylene ether glycol (PTMEG), also known as hexamethylcyclotrisiloxane polyether exporter. PTMEG and toluene diisocyanate (TDI) made of wear resistance, oil resistance, low temperature performance, high strength of special rubber; Block polyether polyester elastic 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, used in the production of tetrahydrothiophene, 1.2 - dichloroethane and 2.3 - dichloro hexamethylcyclotrisiloxane exporter, e lactone, butyrolactone and pyrrolidone, etc. 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 (identification additive). THF can also be used as a surface treatment agent for synthetic leather.
