<p>Described is a process for the electrochemical fluorination of a substrate, the process comprising the steps of: providing a substrate comprising at least one carbon-bonded hydrogen; preparing a reaction solution comprising the substrate and hydrogen fluoride; passing electric current through the reaction solution sufficient to cause replacement of one or more hydrogens of the substrate with fluorine, the electric current being interrupted through a current cycle defined by current levels comprising an elevated current and a reduced current; wherein the current varies in such a manner that the resistance of the cell operated with interrupted current is lower than the resistance of the cell operated with uninterrupted current.</p> |
