ABSTRACT:
This invention provides a crystalline chromium fluoride having a cubic crystal structure (i.e., chromium trifluoride having an X-ray diffraction powder pattern as shown in Table I); and a catalytic composition comprising cubic chromium trifluoride. This invention also provides a process for changing the fluorine content of halogenated hydrocarbons containing from one to six carbon atoms, in the presence of a chromium-containing catalyst. The process is characterized by the chromium-containing catalyst comprising cubic chromium trifluoride.
