Tetrahydrofuran
Tetrahydrofuran (THF) is an organic compound with the formula (CH2)4O. This colorless, volatile, mobile liquid, which is slightly water-soluble, is primarily used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent.
Properties[edit | edit source]
Tetrahydrofuran is a colorless liquid with an ether-like odor. It is highly flammable and can form explosive peroxides upon storage in the presence of air. The substance is stable under recommended storage conditions.
Production[edit | edit source]
Commercially, tetrahydrofuran is produced on a large scale from 1,4-butanediol. The method involves dehydration of 1,4-butanediol at high temperatures over an acidic catalyst.
Uses[edit | edit source]
Tetrahydrofuran is a widely used industrial solvent. It is a direct precursor to polymers. Poly(tetramethylene ether) glycol (PTMEG), a polymer used for high-performance athletic apparel and swimsuits, is derived from THF.
Safety[edit | edit source]
Exposure to tetrahydrofuran can cause irritation to the eyes and respiratory tract. Prolonged skin contact may cause dermatitis, a skin condition characterized by red, itchy skin.
