THF (tetrahydrofuran), also known as oxopentane, oxolane and tetramethylene oxygen, is a stable substance with low boiling point, colorless and transparent liquid, with ether Same smell. Miscible with water, alcohols, ethers, ketones, esters and hydrocarbons. Flammable. Irritating. Due to its excellent solubility, it is widely used as a solvent or reaction solvent. It is also used as a raw material for the synthesis of substances such as polytetrahydrofuran. Tetrahydrofuran is widely used as a raw material for the manufacture of polytetramethylene ether glycol (PTMEG) and polyurethanes such as homopolyether, copolyether, and ternary copolyether; it is also used in the production of polyurethane elastic lithium tetraborate elastomers, elastic fibers, high elastic rubber and Raw material for some special-purpose coatings; in the pharmaceutical industry, it is used to produce furan series of drugs; in the fragrance industry, it is used to synthesize tetrahydrofuran mercaptan series of fragrances; tetrahydrofuran is also used to manufacture adipic acid, succinic acid (succinic acid) and various compounds of intermediates.
THF|tetrahydrofuran application fields and uses
Tetrahydrofuran, also known as oxopentane, oxolane, and tetramethylene oxygen, is an intermediate for synthesizing the pesticide phenylbutyltin. In addition, it can be directly used to make synthetic fibers and synthetic resins. , synthetic rubber, and is also a solvent for many polymeric materials, precision tapes and electroplating industries. It is also used to make adiponitrile, adipic acid, hexamethylenediamine, succinic acid, butylene glycol, γ-butyrolactone, etc., and is used in medicine Industrially, it can be used in the production of Kebiqing, progesterone, rifomycin and as pharmaceutical solvents.
THF is an important raw material for organic synthesis and a solvent with excellent performance. It is especially suitable for dissolving PVC, polyvinylidene chloride and butylaniline. It is widely used as surface coatings, anti-corrosion coatings, It is a solvent for printing inks, tapes and film coatings, and is used as a reaction solvent. When used in electroplating aluminum liquid, the thickness of the aluminum layer can be controlled arbitrarily and the brightness can be controlled. THF itself can be polycondensed (repolymerized by ring-opening initiated by cations) to form polytetramethylene ether glycol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG is combined with toluene diisocyanate (TDI) to make a special rubber with wear resistance, oil resistance, low temperature performance and high strength; it is made with dimethyl terephthalate and 1,4-butanediol to make block polyether polyester elasticity Material. PTMEG with a relative molecular mass of 2000 and p-methylene bis (4-phenyl) diisocyanate (MDI) are used to make polyurethane elastic fibers (spandex, SPANDEX fibers), special rubber and some special-purpose coatings. In organic synthesis, it is used to produce tetrahydrothiophene, 1.4-dichloroethane, 2.3-diboronic acid pinacol ester chloride, tetrahydrofuran, valerolactone, butyrolactone and pyrrolidone, etc. In the pharmaceutical industry, THF is used to synthesize Kebiqing, rifumycin, progesterone and some hormone drugs. THF is treated with hydrogen sulfide to form 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.
