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 purifying reaction products comprising: providing a reaction product mixture comprising HF, C3Cl3F5, and C3Cl2F6; phase separating the reaction product mixture into a top liquid phase comprising HF and a bottom liquid phase comprising the C3Cl3F5, and C3Cl2F6; and physically separating the top and bottom phases to form a solution comprising one or both of the C3Cl3F5; and C3Cl2F6. 2. The process of claim 1 wherein: the mixture comprises HF, C3Cl4F4, C3Cl3F5, and C3Cl2F6; the bottom liquid phase comprises C3Cl4F4, ...
