Abstract
There are provided methods and systems related to use of one or more lanthanide halides in an electrochemical oxidation of metal halide in anolyte where the metal ion is oxidized from lower oxidation state to higher oxidation state at an anode; and then further use of the one or more lanthanide halides and the metal halide with the metal ion in the higher oxidation state in a halogenation reaction of an unsaturated hydrocarbon or a saturated hydrocarbon to form one or more products comprising halohydrocarbon.
Claims17
A method, comprising:
- contacting an anode with an anode electrolyte wherein the anode electrolyte comprises metal halide, one or more lanthanide halides, and water wherein the one or more lanthanide halides are in concentration range of between about 0.4-10 mol %;
- contacting cathode with a cathode electrolyte;
- applying voltage to the anode and the cathode and oxidizing the metal halide from a lower oxidation state to a higher oxidation state at the anode;
- and
- reacting an unsaturated hydrocarbon or a saturated hydrocarbon with the metal halide in the higher oxidation state and the one or more lanthanide halides in the anode electrolyte, to result in one or more products comprising halohydrocarbon.
A method, comprising:
- contacting an anode with an anode electrolyte wherein the anode electrolyte comprises copper (I) chloride, copper (II) chloride, sodium chloride, cerium (III) chloride, and water;
- contacting cathode with a cathode electrolyte;
- applying voltage to the anode and the cathode and oxidizing the copper (I) chloride to copper (II) chloride at the anode;
- and
- reacting an unsaturated hydrocarbon or a saturated hydrocarbon with the copper (II) chloride and the cerium (III) chloride in the anode electrolyte, to result in one or more products comprising halohydrocarbon.
