Tetrafluoroethylene (TFE) is a chemical compound with the formula C2F4. It belongs to the family of fluorocarbons and is the simplest perfluorinated alkene. Tetrafluoroethylene is a colorless, odorless gas. Like all unsaturated fluorocarbons it is susceptible to nucleophilic attack. It is unstable towards decomposition to C and CF4 and prone to form explosive peroxides in contact with air.
TFE is manufactured from chloroform. Chloroform is fluorinated by reaction with hydrogen fluoride to produce chlorodifluoromethane (R-22). Pyrolysis of chlorodifluoromethane (at 550-750 °C) yields TFE, with difluorocarbene as an intermediate.
CHCl3 + 2 HF → CHClF2 + 2 HCl2 CHClF2 → C2F4 + 2 HCl
TFE is used primarily in the industrial preparation of polymers. Polymerization of tetrafluoroethylene produces polytetrafluoroethylene (PTFE) polymers such as Teflon and Fluon.Source: Infogalactic, Tetrafluoroethylene.
