PURPOSE: A process of reducing PFC/HFC (perfluorinated compound/hydrogen fluoride compound) via an electrochemical route is provided, in which PFCs/HFCs are treated with a relatively strong chemical reducing agent, typically an alkali such as lithium, potassium, or sodium, in a system that promotes ionization of the alkali by inclusion of ammonia or other compound that promotes dissolution of the alkali to ions. CONSTITUTION: The electrochemical potential arising from the ionization process provides sufficient energy to extract the fluorine atoms from the PFCs/HFCs. The system also contains a weak acid proton donor to provide a hydrogenation source. The weak acid is believed to displace the reaction equilibrium by protonation, to allow the reaction to proceed at a sufficient rate.
