Hexafluoropropylene is the fluoroalkene with the formula CF<sub>3</sub>CF=CF<sub>2</sub>. It is the perfluorocarbon counterpart to the hydrocarbon propylene. It is mainly used to produce copolymers with tetrafluoroethylene. Hexafluoropropylene is used as a chemical intermediate.
Hexafluoropropylene can be produced by pyrolysis of tetrafluoroethylene:
It can also be prepared from chlorodifluoromethane, or produced from various chlorofluorocarbons.
