Manufacture of organic fluorine compounds

Claim 1

THE METHOD OF MAKING A HIGHLY FLUORINATED COMPOUND WHICH COMPRISES REACTING AT A TEMPERATURE BELOW 200* C. AND AT ABOUT NORMAL ATMOSPHERIC PRESSURE A HALOGENATED ALIPHATIC HYDROCARBON SELECTED FROM THE GROUP CONSISTING OF HALOGENATED HEPTANES, HEPTENES, OCTANES AND OCTENES IN WHICH AT LEAST HALF BUT NOT ALL OF THE HYDROGEN CONTENT HAS BEEN REPLACED BY FLUORINE AND CHLORINE AND WHICH CONTAINS AT LEAST 3 ATOMS OF CHLORINE PER MOLECULE WITH FROM 0.375 TO 0.60 MOL OF A FLUORINATING AGENT OF THE GROUP CONSISTING OF ANTIMONY AND ARSENIC PENTAFLUORIDES FOR EACH GRAM-ATOM OF CHLORINE CONTAINED IN SAID HALOGENATED HYDROCARBON TO EFFECT PARTIAL REPLACEMENT OF CHLORINE ATOMS BY FLUORINE ATOMS, SEPARATING A LESS COMPLETELY FLUORINATED FRACTION FROM THE MORE COMPLETELY FLUORINATED PRODUCT AND FROM INORGANIC SALTS, REACTING THE LESS COMPLETELY FLUORINATED FRACTION WITH AN ADDITIONAL QUANTITY OF SAID FLUORINATING AGENT AT A TEMPERATURE BELOW 200* C., SEPARATING THE MORE COMPLETELY FLUORINATED PRODUCT FROM THE PRODUCTS OF SAID SECOND REACTION, SEPARATING FROM THE MORE COMPLETELY FLUORINATED PRODUCTS BY FRACTIONAL DISTILLATION A CHLORINE-FREE FLUORINE COMPOUND AND A MONOCHLORO FLUORINE COMPOUND AND HEATING VAPORS OF ONE OF SAID COMPOUNDS IN A TEMPERATURE RANGE RUNNING FROM 150* C. TO 350* C. WITH A FLUORINATING AGENT SELECTED FROM THE GROUP CONSISTING OF COF3, AGF2 AND MNF3, WHICH IS CAPABLE OF REPLACING RESIDUAL HYDROGEN TO FORM A STABLE HYDROGEN-FREE ORGANIC FLUORIDE.

Claim 2

THE METHOD OF MAKING A HIGHLY FLUORINATED COMPOUND WHICH COMPRISES REACTING AT A TEMPERATURE BELOW 200* C. AND AT ABOUT NORMAL ATMOSPHERIC PRESSURE A HALOGENATED ALIPHATIC HYDROCARBON SELECTED FROM THE GROUP CONSISTING OF HALOGENATED HEPTANES, HEPTENES, OCTANES AND OCTENES IN WHICH AT LEAST HALF BUT NOT ALL OF THE HYDROGEN CONTENT HAS BEEN REPLACED BY FLUORINE AND CHLORINE AND WHICH CONTAINS AT LEAST 3 ATOMS OF CHLORINE PER MOLECULE WITH FROM 0.375 TO 0.60 MOL OF A FLUORINATING AGENT OF THE GROUP CONSISTING OF ANTIMONY AND ARSENIC PENTAFLUORIDES FOR EACH GRAM-ATOM OF CHLORINE CONTAINED IN SAID HALOGENATED HYDROCARBON TO EFFECT PARTIAL REPLACEMENT OF CHLORINE ATOMS BY FLUORINE ATOMS, SEPARATING A LESS COMPLETELY FLUORINATED FRACTION FROM THE MORE COMPLETELY FLUORINATED PRODUCT AND FROM INORGANIC SALTS, REACTING THE LESS COMPLETELY FLUORINATED FRACTION WITH AN ADDITIONAL QUANTITY OF SAID FLUORINATING AGENT AT A TEMPERATURE BELOW 200* C., SEPARATING THE MORE COMPLETELY FLUORINATED PRODUCT FROM THE PRODUCTS OF SAID SECOND REACTION, SEPARATING FROM THE MORE COMPLETELY FLUORINATED PRODUCTS BY FRACTIONAL DISTILLATION A CHLORINE-FREE FLUORINE COMPOUND AND A MONOCHLORO FLUORINE COMPOUND AND HEATING VAPORS OF ONE OF SAID COMPOUNDS IN A TEMPERATURE RANGE RUNNING FROM 150* C. TO 350* C. WITH A FLUORINATING AGENT SELECTED FROM THE GROUP CONSISTING OF COF3, AGF2 AND MNF3, WHICH IS CAPABLE OF REPLACING RESIDUAL HYDROGEN TO FORM A STABLE HYDROGEN-FREE ORGANIC FLUORIDE.
