Specifications 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.Synonyms: THF; Butylene oxide; Oxolane; Tetramethylene oxideMolecular Formula: C4H8OMolecular Weight: 72.11Linear Structural Formula: C4H8OMDL Number: MFCD00005356Purity: >=99.9%Melting Point: -108 C (lit.)Density: 0.889 g/mL at 25 C (lit.)Refractive Index: n20/D 1.407 (lit.)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.Legal Information: Pure-Pac is a registered trademark of Sigma-Aldrich Co.
