Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH2)4O. The compound is classified as a 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.
The other main application of THF is as an industrial solvent for polyvinyl chloride (PVC) and in varnishes. It is an aprotic solvent with a dielectric constant of 7.6. It is a moderately polar solvent and can dissolve a wide range of nonpolar and polar chemical compounds. THF is water-miscible and can form solid clathrate hydrate structures with water at low temperatures.
THF has been explored as a miscible co-solvent in an aqueous solution to aid in the liquefaction and delignification of plant lignocellulosic biomass for the production of renewable platform chemicals and sugars as potential precursors to biofuels. Aqueous THF augments the hydrolysis of glycans from biomass and dissolves the majority of biomass lignin making it a suitable solvent for biomass pretreatment.
THF is often used in polymer science. For example, it can be used to dissolve polymers prior to determining their molecular mass using gel permeation chromatography. THF dissolves PVC as well, and thus it is the main ingredient in PVC adhesives. It can be used to liquefy old PVC cement and is often used industrially to degrease metal parts.
THF is used as a component in mobile phases for reversed-phase liquid chromatography. It has a greater elution strength than methanol or acetonitrile but is less commonly used than these solvents.
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 a 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. It is more basic than diethyl ether and forms stronger complexes with Li+, Mg2+, and boranes. It is a popular solvent for hydroboration reactions and for organometallic compounds such as organolithium and Grignard reagents. Thus, while diethyl ether remains the solvent of choice for some reactions (e.g., Grignard reactions), THF fills that role in many others, where strong coordination is desirable and the precise properties of ethereal solvents such as these (alone and in mixtures and at various temperatures) allow fine-tuning modern chemical reactions.
Commercial THF contains substantial water that must be removed for sensitive operations, e.g. those involving organometallic compounds. Although THF is traditionally dried by distillation from an aggressive desiccant, molecular sieves are superior.
This product is an organic solvent with excellent properties. It has been widely used due to its fast dissolution rate and good permeability and diffusion on the surface and inside of the resin. It is used as a solvent in format reaction, polymerization reaction, LiAlH4 reduction condensation reaction, and esterification reaction. The dissolution of POLYvinyl chloride, PVC-VINylidene chloride, and its copolymers yield a solution of low viscosity, which is often used in the manufacture of surface coatings, protective coatings, adhesives, and films. Also used in ink, paint remover, extraction agent, artificial leather surface treatment, and so on. This product is self-polymerization and copolymerization, can produce polyether type polyurethane elastomer, its characteristics are high resilience. This product is an important chemical raw material, can be prepared butadiene, polyvinylpyrrolidone, polybutanediol ether, -butyrolactone, polyvinylpyrrolidone, tetrahydrothiophene, etc. This product is also an intermediate in the organic synthesis of drugs.
