Product Information
Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH2)4O. The compound is classified as heterocyclic compound. 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.

Operation and Storage
Store in a cool, ventilated warehouse. Keep away from fire and heat source. It should be stored separately from oxidants, acids, alkalis and edible chemicals, and should not be mixed. Equip the appropriate type and quantity of fire fighting equipment. The storage area shall be equipped with leakage emergency treatment equipment and appropriate holding materials. 
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.
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.
