◎ 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.
