Hexafluoropropylene

Hexafluoropropylene is a compound with the formula C3F6. It is a fluorocarbon alkene in which all of the hydrogen atoms in propylene are replaced by fluorine atoms. It is used as a chemical intermediate.[1] It can be produced by pyrolysis of tetrafluoroethylene or chlorodifluoromethane, or produced from various chlorofluorocarbons [2]
