DESCRIPTION
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]
