Methods and materials are disclosed for the conversion hydrofluorocarbons. More specifically methods and materials are provided for converting hydrofluorocarbons such as HFC-227, HFC-236, HFC-245, HFC-125, HFC-134, HFC- 143, HFC-152, HFC-32, HFC-23 and their respective isomers. Methods are provided for converting hydrofluorocarbons such as these to fluoromonomer precursors such as CFC-217, CFC-216, CFC-215, CFC-115, CFC-114, CFC-113, CFC- 112, CFC-22, HCFC-22, CFC-12, CFC-13 and their respective isomers. Materials and methods are provided for the conversion of these fluoromonomer precursors to fluoromonomers such as HFP, PFP, TFP, TFE, and VDF.
L'invention concerne des procédés et des matériaux de conversion d'hydrofluorocarbones. Elle concerne plus particulièrement des procédés et des matériaux de conversion d'hydrofluorocarbones, tels que HFC-227, HFC-236, HFC-245, HFC-125, HFC-134, HFC-143, HFC-152, HFC-32, HFC-23 et leurs isomères respectifs. L'invention concerne des procédés de conversion d'hydrofluorocarbones, tels que ceux cités plus haut, en précurseurs de monomères fluorés, tels que CFC-217, CFC-216, CFC-215, CFC-115, CFC-114, CFC-113, CFC-112, CFC-22, HCFC-22, CFC-12, CFC-13 et leurs isomères respectifs. Elle concerne en outre des matériaux et des procédés de conversion desdits précurseurs de monomères fluorés en monomères fluorés, tels que HFP, PFP, TFP, TFE et VDF.
