Claims

1. A NEW AND USEFUL ELECTROCHEMICAL PROCESS OF MAKING FLUORINE-CONTAINING CARBON COMPOUNDS FROM FLUORINATABLE ORGANIC STARTING COMPOUNDS, WHICH COMPRISES ELECTROLYZING FOR A PERIOD OF HOURS A CURRENT-CONDUCTING MIXTURE OF THE ORGANIC STARTING MATERIAL IN LIQUID HYDROGEN FLUORIDE FREE FROM WATER IN MORE THAN A SMALL PROPORTION AS HEREIN DESCRIBED, AT A TEMPERATURE AND PRESSURE AT WHICH A LIQUID STATE IS MATAINED AND AT A CELL VOLTAGE WHICH IS INSUFFICIENT TO GENERATE FREE FLUORINE UNDER THE EXISTING CONDITIONS BUT WHICH IS SUFFICIENT TO CAUSE THE PRODUCTION OF FLUORINE-CONTAINING CARBON COMPOUND PRODUCTS AT A USEFUL RATE, AND RECOVERING AT LEAST ONE FLUORINE-CONTAINING CARBON COMPOUND PRODUCT OF THE PROCESS.
