CA 2614530
There is provided a hydrogenation process comprising contacting a compound with a catalyst in the presence of water to form a hydrogenated compound preferably the contacting further compounds contacting the compound with H2. There is also provided a process for purifying CF3CFHCF3 comprising distilling a mixture comprising CF3CFHCF3, CF3CF2CF2H, and at least one chlorofluorocarbon to form a solution comprising CF3CFHCF3. There is also provided a process for purifying chlorofluorinated compounds comprising: providing a reaction product comprising HCl and/or HF, and a at least C-3 chlorofluorinated compound; phase separating the reaction product into a gas phase comprising the HCl, a top liquid phase comprising the HF, and a bottom liquid phase comprising the C-3 chlorofluorinated compound; and removing the bottom liquid phase to form a solution comprising the C-3 chlorofluorinated compound. There are also provided other related processes for separating, purifying and/or halogenating compounds such as chloro or hydro fluorinated compounds.
