CAS No: 116-15-4.

Molecular formula: C3F6.

Molecular weight: 150.02

Uses: it can be used to prepare many kinds of fluorine-containing fine chemical products, pharmaceutical intermediates, fire extinguishing agents and other raw materials, as well as fluorinated polymer materials.

Production method: obtained by pyrolysis of tetrafluoroethylene. Tetrafluoroethylene was cracked in a high temperature cracking furnace at 700 ℃. After acid removal, drying and compression, the cracking gas was coarse distilled, the distillate was frozen and degassed, and finally the finished product was obtained by distillation.
