Chemical compound

Hexafluoropropylene is the fluoroalkene with the formula CF3CF=CF2. 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.

Preparation

Hexafluoropropylene can be produced by pyrolysis of tetrafluoroethylene:

3 CF2=CF2 → 2 CF3CF=CF2

It can also be prepared from chlorodifluoromethane, or produced from various chlorofluorocarbons.
