    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.

    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.
