(also tetramethylene oxide or furanidine), a colorless liquid with an ether-like odor. Tetrahydrofuran is miscible with water and many organic solvents. It boils at 65.6°C and has a density of 0.889 g/cm3 at 20°C.

Tetrahydrofuran is obtained by the catalytic hydrogenation of furan. It is typically used as a solvent for polyvinyl chloride or to replace ethyl ether in the laboratory synthesis of organomagnesium compounds, particularly magnesium vinyl bromide. The products of the homopolymerization and copolymerization of tetrahydrofuran are used as starting materials in the manufacture of urethane rubbers.


(organic chemistry)
C4H8O A clear, colorless liquid with a boiling point of 66°C; soluble in water and organic solvents; used as a solvent for resins and in adhesives, printing inks, and polymerizations. Abbreviated THF.
