THF) is a cyclic ether. It is a colorless liquid with low viscosity and miscible with water at room temperature and pressure. Its chemical formula can be written as (CH2)4O. Due to its long liquid range, it is a commonly used medium polar aprotic solvent. Its main use is as a precursor of high molecular polymers.
Thf The Cornerstone of Modern Organic ChemistryTHF is produced in quantities of about 200,000 tonnes per year. [2] The most widely used method is the acid-catalyzed dehydration , similar to the dehydration of ethanol to produce ethylene. Butanediol can be obtained by carbonylation of acetylene followed by hydrogenation. DuPont has developed a method for producing by oxidation followed by catalytic hydrogenation. [3] Butanediol can also be produced by hydroformylation followed by hydrogenation.

THF can also be produced by catalytic hydrogenation of f. .F can be derived from pentose sugars. However, this method is not widely used.
Thf The Cornerstone of Modern Organic ChemistryTHF can be polymerized into chain-like polytetramethylene oxide (PTMEG) in a strong acidic environment. CAS No. [25190-06-1], also known as PTMO, which stands for "polytetramethylene oxide". Its basic use is to make elastic polyurethane fibers, such as spandex.Thf The Cornerstone of Modern Organic Chemistry
