[Purpose 1]
Used as chromatographic reagent, organic solvent and intermediate of nylon 66
[Purpose 2]
Used as solvent and raw material for organic synthesis
[Purpose 3]
Tetrahydrofuran heterocyclic rings, also known as a oxygen oxygen pentane, tetramethylene oxide, is a synthetic pesticides benzene Ding Xi intermediates, on the other hand, can be directly used in synthetic fiber, synthetic resin, synthetic rubber, is also many polymer materials, precision tape and electroplating industrial solvents, are also used in adiponitrile, adipic acid, hexamethylenediamine, succinic acid, butyl glycol, gamma butyrolactone and so on, in the pharmaceutical industry, cough will clear, and can be used in the production of progesterone, complex and solvent used in pharmaceutical, etc.
[Purpose 4]
THF is an important raw material for organic synthesis and a solvent with excellent performance, especially suitable for dissolving PVC, pvC-VINylidene chloride and butaniline. It is widely used as a solvent for surface coatings, anticorrosive coatings, printing inks, magnetic tape and film coatings, as well as as a reaction solvent. It can be used to control the thickness and brightness of aluminum coating when electroplating aluminum solution.
THF itself is polycondensation (cationic initiated ring-opening repolymerization) into polytetramethylene ether diol (PTMEG), also known as tetrahydrofuran homopolyether.
PTMEG and TOLuene diisocyanate (TDI) are made into special rubber with good wear resistance, oil resistance, low temperature performance and high strength.
Block polyether polyester elastomer was prepared with dimethyl terephthalate and 1, 4-butanediol.
Polyurethane elastic fibers (SPANDEX), special rubber and some special purpose coatings are made from 2000 PTMEG and p-methylene bis (4-phenyl) diisocyanate (MDI).
In organic synthesis, used for the production of tetrahydrothiophene, 1.4-dichloroethane, 2.3-dichlorotetrahydrofuran, valeride, butyllactone and pyrrolidone, etc.
In the pharmaceutical industry, THF is used to synthesize kepidine, rifamycin, progesterone, and some hormonal drugs.
THF is treated with hydrogen sulfide to produce tetrahydrothiophenol, which can be used as odor agent (identification additive) in fuel gas.
THF can also be used as a surface treatment for synthetic leather.
[Purpose 5]
Tetrahydrofuran (109-99-9) is an important raw material for organic and fine chemicals. It is used as a solvent for natural and synthetic resins (especially vinyl resins), and also for the production of butadiene, adiponitrile, adipic acid, adiamine, etc.
Widely used in resin solvents (tape coating, surface coating, cleaning reactor, film removal, cellophane coating, plastic printing ink, thermoplastic polyurethane coating);
Reaction solvents (format reagents, alkyl and aryl alkali metal compounds, aluminum and boron hydride, steroids and macromolecular organic polymers);
Chemical intermediates (polymerization, natural gas flavoring agent);
Chromatographic solvent (gel permeation chromatography).
[Purpose 6]
