Systems and methods for producing fluorocarbons are provided that include contacting a saturated halogenated fluorocarbon with hydrogen and catalyst to produce a saturated hydrofluorocarbon and an unsaturated fluorocarbon. Aspects of the present invention describe systems and methods for contacting saturated halogenated fluorocarbons such as CFCClFCFand/or CFCClCFwith hydrogen and catalyst. Systems and methods of the present invention also describe contacting saturated halogenated fluorocarbons with catalysts having one or more of K, Zr, Na, Ni, Cu, Ni, Zn, Fe, Mn, Co, Ti, and Pd. Aspects of the present invention also describe contacting saturated halogenated fluorocarbons with hydrogen under pressure. Saturated hydroflourocarbons and unsaturated fluorocarbons produced in accordance with the systems and methods of the present invention can include one or more of CFCFHCF, CFCHCF, CFCHClCF, CFCF&#x2550;CF, CFCH&#x2550;CF, and CFCCl&#x2550;CF.

Systems and methods for producing fluorocarbons

Methods and materials are provided for the production of essentially isomerically pure perhalogenated and partially halogenated compounds. One embodiment of the present invention provides a process for the production of essentially isomerically pure CFC-216aa. Other embodiments include processes for the production of CFC-217ba and HFC-227ea. Particular embodiments of the present invention provide separation techniques for the separation of chlorofluorocarbons from HF, from other chlorofluorocarbons, and the separation of isomers of halogenated compounds. Still other embodiments of the present invention provide catalytic synthetic techniques that demonstrate extended catalyst lifetime. In other embodiments, the present invention provides catalytic techniques for the purification of isomeric mixtures.
