Abstract
Disclosed herein are methods and systems that relate to electrochemically oxidizing metal halide with a metal ion in a lower oxidation state to a higher oxidation state; halogenating an unsaturated hydrocarbon or a saturated hydrocarbon with the metal halide with the metal ion in the higher oxidation state; and oxyhalogenating the metal halide with the metal ion from a lower oxidation state to a higher oxidation state in presence of an oxidant. In some embodiments, the oxyhalogenation is in series with the electrochemical oxidation, the electrochemical oxidation is in series with the oxyhalogenation, the oxyhalogenation is parallel to the electrochemical oxidation, and/or the oxyhalogenation is simultaneous with the halogenation.
