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 Ashland/ISP is one of the biggest producers of this chemical route. The method is similar to the production of diethyl ether from ethanol. 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-butanediol
.

Product Application

                    
 

China Supplier CAS 109-99-9 Thf Tetrahydrofuran/Thf

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.
