TITLE FLUORINATION PROCESS ABSTRACT OF THE DISCLOSURE A continuous process for fluorinating haloalkanes containing at least one nonfluorine halogen atom wherein antimony pentachloride is reacted with HF to produce an antimony chlorofluoride. The antimony chlorofluoride thus produced is then transferred to a separate reaction zone where it is reacted with the haloalkane, thereby replacing a portion of the nonfluorine halogen in the haloalkane with fluorine of the antimony chlorofluoride. The continuous process may be used in the manufacture of fluorinated derivatives of alkanes.
