Application

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

General description

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

Other Notes

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