PROCESSES FOR PRODUCING 2-CHLORO-1,1,1,2-TETRAFLUOROPROPANE AND 2,3,3,3-TETRAFLUOROPROPENE

To provide processes for efficiently and economically producing 2-chloro-1,1,1,2-tetrafluoropropane (R244bb) and 2,3,3,3-tetrafluoropropene (R1234yf) in an industrially practical manner. A process for producing 2-chloro-1,1,1,2-tetrafluoropropane, which comprises a chlorination step of reacting 1,2-dichloro-2-fluoropropane and chlorine in the presence of a solvent under irradiation with light to obtain 1,1,1,2-tetrachloro-2-fluoropropane, and a fluorination step of reacting the 1,1,1,2-tetrachloro-2-fluoropropane obtained in the chlorination step and hydrogen fluoride in the presence of a catalyst to obtain 2-chloro-1,1,1,2-tetrafluoropropane, and a process for producing 2,3,3,3-tetrafluoropropene, which comprises dehydrochlorinating it in the presence of a catalyst.

REACTIONS OF HALOGEN FLUORIDES. X. FLUORINATION OF CHLORINE-SUBSTITUTED ALKANES WITH BROMINE TRIFLUORIDE

Bromine trifluoride in Freon 113 readily substitutes the chlorine atoms in monochloroalkanes by fluorine, while in the presence of catalytic amounts of certain Lewis acids it is also capable of substituting the chlorine atoms in polychloroalkanes with the formation of the corresponding fluorides.Additions of tin tetrachloride make it possible not only to increase the reaction rate but also to increase the selectivity of fluorination.In some cases substitution of a primary chlorine atom is accompanied by hydride transfers.
