Claim 1
Independent Claim
125 words
THE PROCESS OF PREPARING A POLYFLUORO-1-OLEFIN WHICH COMPRISES REACTING, AT A TEMPERATURE OF FROM ABOUT 80 TO ABOUT 150*C. AND AT A PRESSURE UP TO ABOUT ONE ATMOSPHERE, A ONE MOLAR PROPORTION OF AN ALKALI METAL ALKOXIDE IN SUSPENSION IN AN INERT LIQUID WITH AT LEAST A ONE MOLAR PROPORTION OF A LOWER ALKYL ESTER OF AT LEAST ONE ACID FROM THE GROUP CONSISTING OF POLYFLUOROPERHALOCARBOXYLIC AND OMEGA-HYDROPOLYFLUOROPERHALOCARBOXYLIC ACIDS, WHEREIN THE HALO SUBSTITUENTS ARE OF ATOMIC NUMBER 9-17 AND WHEREIN THE RADICAL ATTACHED DIRECTLY TO THE CARBOXYL CARBON HAS AT LEAST TWO CHAIN CARBONS, THE ALPHA CARBON OF WHICH CARRIES AT LEAST TWO MEMBERS FROM THE GROUP CONSISTING OF FLUORINE AND PERFLUOROCARBON RADICALS AND THE BETA CARBON OF WHICH CARRIES AT LEAST ONE FLUORINE RADICAL,
