May 30, 2018

 

Tetrahydrofuran is a transparent , colorless liquid and can be dissolved in water and many organic solvents. In the air , it can be oxidized to from explosive peroxides.

 Freezing point :-108.56℃     Boiling point: 66℃

 Relative density :0.8892 (25℃)    Refractive index :1.4050 (20℃)     Flash point: -15℃

 

Tetrahydrofuran (THF) is an industrial solvent widely recognized for its unique combination of useful properties. It is used as a resin solvent for uncured and thermoplastic polyurethanes used in coating media, such as magnetic tapes and synthetic leather. It is also used in PVC top coating, reactor cleaning and film casting—in addition to cellophane coating and printing inks for plastics.

THF is a chromatographic solvent for gel permeation chromatography and a reaction solvent for:

  • Grignard reagents

  • Alkali metals, alkyl and arylalkali metal compounds

  • Alkali metal aluminum hydrides and borohydrides

  • Steroids and high-molecular-weight organic polymers
