Tetrahydrofuran
It is a heterocyclic organic compound., It is the complete product of aromatic compound furan. It is used as an aprotic solvent with medium polarity in chemical reaction and extraction. Tetrahydrofuran is partially miscible with water at room temperature. Tetrahydrofuran is easy to become peroxide during storage. Therefore, BHT, i.e. 2,6-di-tert-butyl-p-cresol, is often used for commercial tetrahydrofuran to prevent oxidation. Tetrahydrofuran can be stored in a dark place in a sealed bottle by * * *.
Function and use
Tetrahydrofuran
1. Used as solvent and raw material for organic synthesis.
2. It is used as chromatographic reagent, organic solvent and nylon 66 intermediate. Tetrahydrofuran is also known as pentaoxygene, oxyheterocyclopentane and tetramethylene oxygen. In addition, it can be directly used to produce synthetic fibers synthetic resin 、 synthetic rubber It is also a solvent for many polymeric materials, precision magnetic tapes and electroplating industries.
3. Tetrahydrofuran is an important organic synthetic raw material and a solvent with excellent performance. It is widely used as a solvent for surface coatings, anti-corrosion coatings, printing inks, tape and film coatings, and as a reaction solvent. When it is used for electroplating aluminum solution, the thickness of aluminum layer can be controlled arbitrarily and it is bright. Raw materials for special rubber and some special purpose coatings. In organic synthesis, it is used to produce tetrahydrothiophene.
