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 in a sealed bottle with sodium hydroxide.

 

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).

 

Storage Precautions Usually products contain in a cool, ventilated warehouse.Keep away from fire and heat sources.The storage temperature should not exceed 29ºC.The packaging must be sealed and must not come into contact with air.They should be stored separately from oxidants, acids, alkalis, etc. and avoid mixed storage.Use explosion-proof lighting and ventilation facilities.It is prohibited to use mechanical equipment and tools that are prone to sparks.The storage area should be equipped with emergency release equipment and suitable containment materials.
