ABSTRACT:
A process for separating carbon dioxide from an unsaturated fluorinated compound carbon dioxide mixture comprising contacting the unsaturated fluorinated compound carbon dioxide mixture with a semipermeable membrane to form at least one exit stream having an increased concentration of carbon dioxide and at least one other exit stream having a reduced concentration of carbon dioxide.
