Tetrahydrofuran is a type of heterocyclic organic compound. It is one of the strong polar ethers and is used as a medium polar solvent in chemical reactions and extraction. Colorless and volatile liquid with an odor similar to ether. Soluble in most organic solvents such as water, ethanol, ether, acetone, benzene, etc.

Chemical nature

It can be explosive when mixed with air; it can form explosive peroxides in the air, which is flammable when exposed to open flames, high temperatures and oxidants; burning produces irritating smoke. Tetrahydrofuran

Tetrahydrofuran ball and stick model

It is a heterocyclic organic compound. Belongs to ethers, which is the completely hydrogenated product of aromatic compound furan. Used as a medium polar aprotic solvent in chemical reactions and extraction. Tetrahydrofuran is partially miscible with water at room temperature, and some illegal reagent dealers use this to make profits by mixing tetrahydrofuran reagent with water. Tetrahydrofuran tends to become peroxides during storage. Therefore, commercial tetrahydrofuran often uses BHT, 2,6-di-tert-butyl-p-cresol to prevent oxidation. Tetrahydrofuran can be stored in a dark place with sodium hydroxide in a sealed bottle.
