Product Description

 

Used as a moderately polar aprotic solvent in chemical reactions and extractions.Tetrahydrofuran is a colorless, low-viscosity liquid with an ether-like odor.Tetrahydrofuran and water are partially miscible at room temperature. Some unscrupulous reagent dealers take advantage of this fact to make huge profits by mixing tetrahydrofuran reagent with water.Tetrahydrofuran easily turns into peroxide during storage.Therefore, commercial tetrahydrofuran often uses BHT, that is, 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.

Colorless transparent liquid.Smells of ether.It is an important organic chemical and fine chemical raw material, widely used in resin solvents (tape coating, PVC surface coating, cleaning PVC reactor, removing PVC film, cellophane coating, plastic printing ink, thermoplastic polyurethane coating) ; Reaction solvents (Grignett reagents, alkyl alkali metal compounds and aryl alkali metal compounds, aluminum hydride and boron hydride, steroid compounds and macromolecular organic polymers); chemical intermediates (polymerization to form PTMEG, natural gas odorant); chromatography Solvent (gel permeation chromatography).

Tetrahydrofuran (THF) is a type of heterocyclic organic compound. It is one of the strongest polar ethers and is used as a moderately polar solvent in chemical reactions and extractions. It is a colourless, clear liquid with an ether-like odour. It has a relative density of 0.89, a molecular weight of 72.11, a melting point of -108.5°C, a boiling point of 66°C, a flash point of -17.2°C, and a self-ignition point of 321.1°C. Its refractive index is 1.407.
