General description
Tetrahydrofuran (THF) is a saturated cyclic ether with a potential use as a biofuel. Its combustion studies have been reported. Reports suggest it is a better promoter than 1,3 dioxolane for CO2-hydrate formation. The effect of THF on the biological systems has been studied.
Application
Tetrahydrofuran may be used as a solvent in the following processes:
• Formation of diacetylinic polymers.
• RAFT polymerization of p-acetoxystyrene.
• Synthesis of di-tert-butyl-Phosphinoferrocene.
It may be used in the following processes:
• As mobile phase solvent in high-performance liquid chromatography.
• As a solvent in the preparation of spin-coated poly(bisphenol A decane ether).
• Formation of butyrolactone (BTL) by green oxidation method.
• As a solvent for lignin depolymerization to isolate phenolic monomer.
