ABSTRACT:
The instant invention relates to producing fluorinated propanes and pentanes. More particularly it relates to producing perhalofluoropropanes and pentanes by reacting dihalodifluoromethanes with polyfluoroethylenes, notably tetrafluoroethylene (TFE) and chlorotrifluoroethylene (CTFE) while in the presence of an aluminum chlorofluoride catalyst.
