1. A process for preparing 2-chloro-3,3,3-trifluoropropene comprising fluorinating in a liquid phase in an organic medium a reactant comprising 1,1,1,2,3-pentachloropropane or/and 1,1,2,2,3-pentachloropropane in the presence of a catalyst, wherein the organic medium is selected from the group consisting of 1,2-dichloroethane, 1,2,3-trichloropropane, 1-chloro-1-fluoroethane, 1,1-difluoroethane, 1,1-dichloro ethane and 1,3-dichloro-1-fluorobutane, tetrachlorofluoropropane isomers, trichlorodifluoropropane isomers and dichlorotrifluoropropane isomers, 1,1,1,3,3-pentafluorobutane and 1,1,2-trichloro-2,2-difluoroethane, nitrated solvents including nitromethane and nitrobenzene, sulfones including tetramethylene sulfone and dimethyl sulfone, 1,1,2-trichloro-2-fluoroethane, perchloroethylene, and mixtures thereof. |
