应用

Tetrahydrofuran is used as a solvent in Grignard reagent formation processes, pharmaceutical steroids and in the preparation of organometallic reagents.It is used for HPLC, spectrophotometry and environmental testing.It is used as a resin solvent in flexographic inks for plastics coating deposition for audio and video tapes.It is used in PVC and CPVC pipe cements, polyurethane coatings and in PVC film castings.

注释

Filtered through 0.2µ filters. Suitable for spectophotometry, chromatographyHighly flammable. Oxidizes readily in air to form unstable peroxides.THF exhibits high volatility and an extremely low freezing point.Keep the container tightly closed and sealed until ready for use.
