Carbon tetrafluoride, from decomposition

Tetrafluoroethylene boils at -76.3 C. It is not the only product from the above pyrolytic reaction of difluorochloromethane. Other fluorine byproducts form as well and the monomer must be isolated. The monomer polymerizes in water at moderate pressures by a free-radical mechanism. Various initiators appear effective. Redox initiation is preferred. The polymerization reaction is strongly exothermic and water helps dissipate the high heat of the reaction. A runaway, uncontrolled polymerization can lead to explosive decomposition of the monomer to carbon and carbon tetrafluoride ...
