Advantages of Tetrahydrofuran liquid.

Global ASAP Nutrition Factory Tetrahydrofuran (THF) is an important organic solvent that is widely used in many fields such as chemical industry, pharmaceutical industry, and electronic industry, with organic solvents being the main use.

In 2022, high quality the global market is divided into textiles, paints and coatings, packaging, polymers, etc. The packaging segment accounted for the largest revenue share in 2022. With the increasing demand for polyvinyl chloride in the packaging industry, the increasing use of tetrahydrofuran as a solvent for polyvinyl chloride industry has led to the packaging industry occupying the highest position in the global market.

The tetrahydrofuran (THF) market is expected to grow at a CAGR of 6% by 2028. The growing demand for spandex in the textile industry is driving the growth of the tetrahydrofuran industry.

Uses of Tetrahydrofuran liquid.

Organic synthesis: THF is a commonly used organic synthesis solvent and is widely used in many organic synthesis reactions, such as Grignard reaction, metal catalysis reaction, esterification reaction, etc. It can dissolve many organic compounds, making them easier to occur in the reaction.

Polymerization reaction: THF can be used as a reaction solvent for some polymerization reactions, especially in the process of synthesizing polymer materials such as polyurethane and polyacrylate.

Dissolution of metal ion complexes: Since THF has good solubility for many metal ion complexes, it is widely used in the synthesis of metal organic compounds or in organic metal chemical reactions.

Solvent extraction: THF can be used in chemical separation and extraction processes, such as for extracting natural products, separating compounds in mixtures, etc.

Polymer dissolution: THF is a solvent with strong solubility and can be used to dissolve and process some high molecular polymers, such as polyacrylate and polycaprolactone.

Nature of Tetrahydrofuran.

Tetrahydrofuran (THF) is a heterocyclic organic compound belonging to the ether class and is the complete hydrogenation product of furan. At room temperature, tetrahydrofuran is a colorless, volatile liquid with an ether-like smell. It is soluble in most organic solvents such as water, ethanol, ether, acetone, benzene, etc., and is known as the "universal solvent"

Chemical properties

Tetrahydrofuran is a polar ether, commonly used as a medium-polarity solvent in chemical reactions and extraction processes. It easily mixes with air to form explosive peroxides, is flammable when exposed to open flames, high temperatures, and oxidants, and produces irritating smoke when burned.

Product Method of Tetrahydrofuran.

The earliest industrial production used aldehyde as raw material. The mixture of aldehyde and steam was passed into a reactor filled with zinc-chromium-manganese metal oxide (or palladium) catalyst to remove the carbonyl group at 400-420℃ to form furan; then, using skeleton nickel as catalyst, furan was hydrogenated at 80-120℃ to produce tetrahydrofuran. This method consumes about 3 tons of aldehyde to produce 1 ton of tetrahydrofuran.

There are many production methods developed later. The industrialized method includes the 1,4-butanediol catalytic dehydration cyclization method, because butanediol is made from acetylene and formaldehyde, this method is called the Reppe method; the production of tetrahydrofuran using 1,4-dichlorobutene, a byproduct of chloroprene rubber monomer chloroprene, is called the dichlorobutene method; in recent years, a catalytic hydrogenation method using maleic anhydride as raw material has been developed.
