Definitions
- the present invention relates to the production of fluorocarbons. Aspects of the present invention relate to the production of saturated and unsaturated fluorocarbons.
- Hydrofluorocarbons and fluoromonomers such as 1,1,1,2,3,3,3-heptafluoropropane (CF 3 CHFCF 3 , HFC-227ea) and hexafluoropropene (CF 3 CF ⁇ CF 2 , FC-1216, HFP) are commercially desired.
- HFP is widely employed as a monomer for the production of fluorine-containing polymers, for example, the thermoplastic FEP (“fluorinated-ethylene-propylene”) resins, formed via the copolymerization of tetrafluoroethylene and hexafluoropropene (see for example, Fluorine Chemistry: A Comprehensive Treatment, M. Howe-Grant, ed., Wiley & Sons, New York, N.Y., 1995, page 404).
- FEP fluorinated-ethylene-propylene
