Abstract (en)

[origin: WO9958745A1] Described is a process for the electrochemical fluorination of an alkane substrate, the process comprising the steps of: providing an alkane substrate comprising at least one carbon-bonded hydrogen; preparing a reaction solution comprising the alkane substrate and hydrogen fluoride; passing electric current through the reaction solution sufficient to cause replacement of one or more hydrogens of the alkane 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 non-interrupted current.
