Tetrahydrofuran (THF) Solvent

Category:

Property:

Tetrahydrofuran (THF) is an organic compound with the formula (CH2)4O. It is a colorless, water-miscible organic liquid with low viscosity at standard temperature and pressure. This heterocyclic compound has the chemical formula (CH2)4O. As one of the most polar ethers with a wide liquid range, it is a useful solvent. Its main use, however, is as a precursor to polymers. THF solvent has an odor similar to its chemical cousin, diethyl ether, but is a much less potent anesthetic than diethyl ether.

Uses:

Tetrahydrofuran can be polymerized by strong acids to give a linear polymer called poly(tetramethylene ether) glycol(PTMEG), also known as PTMO, polytetramethylene oxide. The primary use of this polymer is to make elastomeric polyurethane fibers like Spandex.

The other main application of THF solvent is as an industrial solvent for PVC and in varnishes. It is an aprotic solvent with a dielectric constant of 7.6. Tetrahydrofuran is a moderately polar solvent and can dissolve a wide range of nonpolar and polar chemical compounds. Tetrahydrofuran is water-miscible and can form solid clathrate hydrate structures with water at low temperatures.
