General description
Tetrahydrofuran (THF) is a widely used organic solvent. On long term storage it forms organic peroxides. This process can be suppressed by adding butylated hydroxytoluene (BHT) as a stabilizer. BHT removes the free radicals required for the peroxide formation. The effect of THF on the biological systems has been studied.
Application
Tetrahydrofuran (THF) was used as a solvent in the following processes:
• RAFT (Reversible Addition-Fragmentation chain Transfer) polymerization of p-acetoxystyrene.
• Synthesis of di-tert-butyl-phosphinoferrocene.
• Synthesis of n-TiO2-based amphiphilic polymer brushes.
• To dissolve the LiCl from the Mg2Si nanoparticles.
It may be used in the following studies:
• As an O-donor ligand to form coordination complexes.
• As mobile phase solvent in high-performance liquid chromatography.
• As a solvent in the preparation of spin-coated poly(bisphenol A decane ether).
• Synthesis of THF doped hydrogen clathrate hydrates.
