- Tetrahydrofuran, also known as
THF, is a heterocyclic organic compound with the formula (CH2)4O.
- Tetrahydrofuran is a colorless
low-viscosity liquid with a smell similar to diethyl ether.
- THF is one of the most polar
ethers.
- THF is the fully hydrogenated
analog of the aromatic compound furan.
- THF is an aprotic solvent with a
dielectric constant of 7.6.
- THF is a moderately polar, aprotic
solvent that dissolves a wide range of non polar and polar
compounds.
- THF can be polymerized by strong
acids to give a linear polymer called poly (tetramethylene ether) glycol
PTMEG, also known as PTMO, polytetramethylene oxide.
- THF can be synthesized by
catalytic hydrogenation of furan.
The major industrial process for
making THF is the acid-catalyzed dehydration of
1,4-butanediol.
- Du Pont developed a process for
producing THF by oxidizing n-butane to crude maleic anhydride, followed
by catalytic hydrogenation of maleic anhydride to THF.
- THF or diethyl ether are often
used as solvents for Grignard reagents because of the oxygen atom's
ability to coordinate to the magnesium ion component of the Grignard
reagent.
- THF is often used in polymer
science.
- THF can be used to dissolve rubber
prior to determining its molecular mass using gel permeation
chromatography.
- THF dissolves PVC, and is the main
ingredient in PVC adhesives.
- THF can be used to liquefy old PVC
cement.
- Exposure to THF is most likely to
occur in occupational settings through inhalation or by dermal
contact.
- THF has been detected in ambient
air, groundwater, drinking water, landfill sludge, and in some common
household products.
