3. Product Feature And Application of Tetrahydrofuran
1) raw materials of spandex synthesis reaction
The tetrahydrofuran itself can be polycondensation (by cationic ring opening repolymerization) to poly tetramethylene ether diol (PTMEG), also known as tetrahydrofuran homopolyether. PTMEG and toluene diisocyanate (TDI) were used to produce special rubber with good wear resistance, oil resistance, low temperature performance and high strength. Block polyether polyester elastic material was prepared with dimethyl terephthalate and 1, 4-butanediol. The relative molecular weight of 2000 PTMEG and p-methylene bis (4-phenyl) diisocyanate (MDI) to make polyurethane elastic fiber (SPANDEX, SPANDEX), special rubber and some special purpose coatings raw materials.The main use of THF is used to produce PTMEG. According to rough statistics, more than 80% of THF is used to produce PTMEG, while PTMEG is mainly used to produce elastic spandex fiber.
2) solvent with excellent performance
Tetrahydrofuran is a common and excellent solvent, especially suitable for the dissolution of PVC, polyvinylidene chloride and butaniline. It is widely used as a solvent for surface coatings, anticorrosive coatings, printing inks, tape and film coatings. It can be used to control the thickness and gloss of aluminum layer when electrochemicalbook aluminum plating solution.Tape coating, PVC surface coating, cleaning PVC reactor, PVC film removal, cellophane coating, plastic printing ink, thermoplastic polyurethane coating, adhesive solvent, widely used in surface coatings, protective coatings, inks, extractants and artificial synthetic leather surface treatment agent.
3) used as raw materials for pharmaceutical and other organic synthesis
For the production of tetrahydrothiophene, 1.4-dichloroethane, 2.3-dichlorotetrahydrofuran, valerolactone, butyrolactone and pyrrolidone, etc. In the pharmaceutical industry, it is used for the synthesis of kopicillin, rifamycin, progesterone and some hormone drugs. Tetrahydrothiophenol is produced by hydrogen sulfide treatment, which can be used as an odorant (identification additive) in fuel gas, and is also the main solvent in the pharmaceutical industry.
4) Other uses
Chromatographic solvent (gel permeation chromatography), used for natural gas flavor, acetylene extraction solvent, polymer material light stabilizer, etc.
4. Product Details of Tetrahydrofuran
Tetrahydrofuran is one of the strongest polar ethers. It is used as a medium polar solvent in chemical reactions and extraction. It is a colorless volatile liquid at room temperature and has a similar odor to diethyl ether.Soluble in water, ethanol, ether, acetone, benzene and other organic solvents, known as the "universal solvent".
Since THF has a tendency to form peroxide in storage, industrial products are usually added with the antioxidant BHT.Water content ≦0.2%. It is characterized by low toxicity, low boiling point and good fluidity.
