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