Tetrahydrofuran Anhydrous >=99.9% 18l Un 2056 3/pg 2, Each

Details:

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.
