A process for producing fluorinated C1 HFCs comprising fluorinating a reactive organic compound to produce a reaction product comprising at least the desired C1 HFC, unreacted reactive organic compound and a byproduct having a boiling point between the boiling point of said desired hydrofluorocarbon compound and said reactive organic compound; and removing from the reaction product at least a substantial portion of the byproduct to produce a high purity product stream.

Method of producing hydrofluorocarbons

The present invention provides a novel process for producing 1,2-dichloro-1,1,2,2-tetrafluoroethane substantially free of the 1,1-isomer. The process includes contacting, in the vapor phase, an organic feed composition containing a major amount of the 1,2-isomer and a minor amount of 1,1-isomer with hydrogen in the presence of a hydrodechlorination catalyst. The process selectively degrades the 1,1-isomer. Also provided is a process for producing high purity 1,2-isomer.
