Tetrahydrofuran THF Uses
Tetrahydrofuran as a fine reaction intermediate can be used as a natural flavor enhancer for tetrahydrothiophene
Tetrahydrofuran is used in medicine to produce carbetapentane citrate progesterone rifumycin etc
Tetrahydrofuran can be used in chemical production to prepare polytetrahydrofuran tetrahydrothiophene 1 4dichlorobutane 2 3dichlorotetrahydrofuran valerolactone ethanediamine 1 4butanediolgammabutyrolactone and many other chemical products
Tetrahydrofuran can also be used as high energy fuel acetylene extraction solvent electroplating coating liquid precision tape cleaning agent leather surface finishing agent light stabilizer of molecular materials etc
The most important use of THF tetrahydrofuran is to produce PTMEG According to rough statistics about 80 of THF in the world is used to produce PTMEG and PTMEG is mainly used to produce spandex fiber
