TETRAHYDROFURAN (THF)

>> TETRAHYDROFURAN (THF) Process : Davy Mckee (KPT) THF is a cycloaliphatic ether with excellent solvent power for a wide variety of synthetic and natural resins. Also, the ether oxygen atom in the molecule is sterically unhindered, which favors the formation of complex compounds (with various metals and salts) and the formation of cation solutions.THF is used in its own right as a solvent and chemically as a precursor of an oligomeric polyether, polytetramethylene ether glycol (PTMEG), which is used also for Spandex fiber. The solvent applications for THF fall into resin and reaction solvents. Production Capacity : 30,000 MTA -.
