Product Description

Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH2)4O. The compound is classified as heterocyclic
compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent.
About 200,000 tonnes of tetrahydrofuran are produced annually. The most widely used industrial process involves the acid-catalyzed
dehydration of 1,4-Butylene glycol. Ashland/ISP is one of the biggest producers of this chemical route. The butanediol is derived from condensation of acetylene with formaldehyde followed by hydrogenation.DuPont developed a process for producing THF by oxidizing n-butane to crude maleic anhydride, followed by catalytic hydrogenation. A third major industrial route entails hydroformylation of allyl alcohol followed by hydrogenation to 1,4-Butylene glycol.

Product Application

Tetrahydrofuran Application

Polymerization
In the presence of strong acids, THF converts to a linear polymer called poly(tetramethylene ether) glycol (PTMEG), also known as polytetramethylene oxide (PTMO)

As a solvent
The other main application of THF is as an industrial solvent for polyvinyl chloride (PVC) and in varnishes.THF is often used in polymer science. THF is used as a component in mobile phases for reversed-phase liquid chromatography.
THF is used as a solvent in 3D printing when using PLA plastics. It can be used to clean clogged 3D printer parts, as well as when finishing prints to remove extruder lines and add a shine to the finished product. Recently THF is used as co-solvent for lithium metal batteries, helping to stabilize the metal anode.

Laboratory use
In the laboratory, THF is a popular solvent when its water miscibility is not an issue.

Reaction with hydrogen sulfide
In the presence of a solid acid catalyst, THF reacts with hydrogen sulfide to give tetrahydrothiophene.
