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.
