Abstract: The present disclosure provides a method for purifying trifluoroiodomethane. The method includes providing a process stream comprising trifluoroiodomethane, organic impurities, and acid impurities; reacting the process stream with a basic aqueous solution, the basic aqueous solution comprising water and at least one base selected from the group of an alkali metal carbonate and an alkali metal hydroxide; and separating at least some of the organic impurities from the process stream.

Abstract: The invention provides an improved process to manufacture 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb) by reacting 2-chloro-3,3,3,-trifluoropropene (HCFO-1233xf) with hydrogen fluoride, in a liquid phase reaction in the presence of hydrogen chloride and a liquid phase fluorination catalyst. The hydrogen chloride is added into the reaction from an external source at a pressure of about 100 psig or more. The HCFC-244bb is an intermediate in the production of 2,3,3,3-tetrafluoropropene-1 (HFO-1234yf).
