Tetrahydrofuran Usage and Synthesis:

Tetrahydrofuran, abbreviated as THF, is a heterocyclic organic compound. It belongs to the group of ethers and is the product of the complete hydrogenation of the aromatic compound furan. Tetrahydrofuran is a class of heterocyclic organic compounds. Tetrahydrofuran is a class of heterocyclic organic compounds. It is one of the strongest polar ethers and is used as a moderately polar solvent in chemical reactions and extractions. It is a colorless and transparent liquid. It has an ether-like odor. . It is commonly used as a solvent, raw material for organic synthesis, and is a commonly used excellent solvent. The most important use in the polyurethane industry is as a monomer for polytetrahydrofuran diol (PTMEG). (PTMEG), which is one of the main uses of THF.

Pharmacokinetics of Tetrahydrofuran:

Relative density of tetrahydrofuran 0.89. Molecular weight 72.11. Melting point -108.5°C. Boiling point 66°C. Boiling point 66℃. Flash point -17.2℃. Auto-ignition point 321.1℃. Refractive index 1.407. It is used as a medium-polar nonprotonic solvent in chemical reactions and extractions. Tetrahydrofuran is a colorless, low-viscosity liquid with an odor similar to that of ether. At room temperature, tetrahydrofuran Tetrahydrofuran is partially miscible with water at room temperature, and some unscrupulous reagent dealers take advantage of this to make a profit by mixing tetrahydrofuran reagent with water. Tetrahydrofuran can easily become peroxide when stored. Therefore Therefore, commercial tetrahydrofuran is often treated with BHT, 2,6-di-tert-butyl-p-cresol, to prevent oxidation. Tetrahydrofuran can be stored by sodium hydroxide in a sealed bottle in a dark place. Storage.

Clinical Application of Tetrahydrofuran:

Tetrahydrofuran is an important organic chemical and fine chemical raw material with low toxicity, low boiling point and good fluidity. It is widely used in resin solvent (tape coating, PVC surface coating, cleaning PVC reactor, removing PVC film, etc.). PVC surface coating, cleaning PVC reactor, PVC film removal, cellophane coating, plastic printing ink, thermoplastic polyurethane coating); reaction solvents (format reagents, alkane alkyl and aryl alkali metal compounds, aluminum and boron hydride, steroid compounds and large organic polymers); chemical intermediates (polymerization to produce PTMEG , natural gas flavoring agents); chromatographic solvents (gel permeation chromatography). Click to learn more.
