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....
What is claimed is: 1. A process for producing CF3CFHCF3 comprising: contacting a C-3 reactant comprising one or more of perhydrogenated or partially halogenated C-3 hydrocarbons with Cl2 and HF in the presence of a first catalyst at a first temperature to form a C-3 product comprising a C-3 perhalogenated compound; contacting the C-3 product with HF in the presence of a second catalyst at a second temperature to form a CF3CCl2CF3 product, the CF3CCl2CF3 product comprising a mole ratio of CF3CCl2CF3 to CF3CF3CFClCClF2 greater than 2:1; contacting the CF...
