Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
45 words
THE PROCESS OF FLUORINATION OF A HALOGENATED ALIPHATIC HYDROCARBON TO REPLACE HALOGEN OTHER THAN FLUORINE WITH FLUORINE COMPRISING CONTACTING THE HALOGENATED ALIPHATIC HYDROCARBON WITH HYDROFLUORIC ACID IN THE PRESENCE OF A GALLIUM FLUORIDE AS A CATALYST AND AT A TEMPERATURE WITHIN THE RANGE OF 150-450*C.
Claim 2
Dependent Claim
45 words
THE PROCESS OF FLUORINATION OF A HALOGENATED ALIPHATIC HYDROCARBON TO REPLACE HALOGEN OTHER THAN FLUORINE WITH FLUORINE COMPRISING CONTACTING THE HALOGENATED ALIPHATIC HYDROCARBON WITH HYDROFLUORIC ACID IN THE PRESENCE OF A GALLIUM FLUORIDE AS A CATALYST AND AT A TEMPERATURE WITHIN THE RANGE OF 150-450*C.
Claim 3
Dependent Claim
107 words
IN THE METHOD OF PREPARING A CATALYST FOR THE FLUORINATION OF A HALOGENATED ALIPHATIC HYDROCARBON TO REPLACE HALOGEN OTHER THAN FLUORINE WITH FLUORINE COMPRISING IMPREGNATING A CARRIER SELECTED FROM THE GROUP CONSISTING OF ACTIVATED CHARCOAL AND ALUMINUM OXIDE WITH A GALLIUM COMPOUND, PASSING HYDROFLUORIC ACID INTO CONTACT WITH THE IMPREGNATED CARRIER AT A TEMPERATURE BETWEEN 150250*C TO CONVERT THE GALLIUM COMPOUND TO A GALLIUM FLUORIDE AND THEN USING THE GALLIUM FLUORIDE ON THE CARRIER AS A CATALYST IN THE FLUORINATION REACTION TO SUBSTITUTE FLUORINE FOR THE HALOGEN ON THE HALOGENATED ALIPHATIC HYDROCARBON IN THE PRESENCE OF HYDROFLUORIC ACID AND AT A TEMPERATURE WITHIN THE RANGE OF 175-450*C.
Claim 4
Dependent Claim
