high quality Tetrahydrofuran 99% min(THF) CAS No.: 109-99-9 Tetrahydrofuran(THF) Usage:
THF for many organic compound have good solubility,it dissolve addition to polyethylene,polypropylene and
fluorine resin,all other organic compounds,especially polyvinyl chloride,polyvinylidene chloride and a good bite dissolution of aniline was widely used as a reactive solvent,the "universal solvent" is known,is an impo
rtant organic chemical and fine chemical raw materials,the main purposes are summarized as follows:
1, under pressure reacts with hydrogen chloride 1,4-dichloro-butane.For natural and synthetic resins (parti
cularly vinyl resins) and solvent,also used for making butadiene,Adiponitrile,adipic acid,hexamethylene diami
ne and so on.
2, are widely used in resin solvents (tape coating,PVC coating,PVC reactor cleaning,removal of PVC film, cellophane coating, plastic printing ink,thermoplastic polyurethane coatings).
3, reaction solvent (format reagents,alkyl aryl alkali metal compound and alkali metal compounds,aluminum
hydride and boron hydride,steroids and macromolecule organic polymer).
4, chemical intermediate product (polymerization PTMEG,natural gas odorants);chromatography solvent (gel
5, as a common solvent,THF has been widely used in surface coatings,protective coatings, inks, extraction and artificial leather surface treatment agent,tetrahydrofuran is the production of poly tetramethylene ether
glycol (PTMEG) an important raw material,is the pharmaceutical industry main solvent.
6, for synthesis of pharmaceutical raw materials, intermediates. Such as tetrahydrothiophene, 1,4 -dibromo-butane,maltol,different plant alcohol,butyl sultone,benzene,tin,Clofentezine,azocyclotin suspension, erythromycin ethyl succinate,acrylic urethane,Quinestrol,norethindrone,levonorgestrel,mifepristone.
7, chromatography solvent. Such as gel permeation chromatography.
