THF for many organic compounds have good solubility, it
dissolve addition to polyethylene, polypropylene and fluorine
resin.
Usage:
THF for many organic compounds 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 important 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 (particularly vinyl resins) and solvent, also
used for making butadiene, Adiponitrile, adipic acid,
hexamethylene diamine 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
products (polymerization PTMEG, natural gas odorants);
chromatography solvent (gel permeation chromatography). 5, as a
common solvent, THF has been widely used in surface coatings,
protective coatings, inks, extraction and artificial leather
surface treatment agents, 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, tramadol hydrochloride, Quinestrol, norethindrone,
levonorgestrel, mifepristone. 7, chromatography solvent. Such
as gel permeation chromatography.

storage and transportation conditions:
Tetrahydrofuran should be stored in cool, dry, well
ventilated place and away from heat,Sparks and open flame.
Transport containers to prevent static electricity to ground,
the container should be sealed well, do not, and oxidant Or
strong acid to be stored. THF as flammable liquids, flammable
liquid containers to be affixed.
