General description

Tetrahydrofuran (THF) is a saturated cyclic ether with a potential use as a biofuel. Its combustion studies have been investigated.[1] Reports suggest that it is a better promoter than 1,3 dioxolane for CO2-hydrate formation.[2]

Application

Tetrahydrofuran was used as a solvent in the formation of diacetylinic polymers.[3]
It may be used in the following processes:
  • Formation of butyrolactone (BTL) by green oxidation method.[4]
  • Aqueous THF solution to modify the polystyrene surface by swelling process.[5]
  • As a solvent for lignin depolymerization to isolate phenolic monomer.[6]

Other Notes

"Greener alternatives are available for many THF applications, 2-Methyltetrahydrofuran (673277) and Cyclopentyl methyl ether (791962)
