Abstract
Disclosed is a method of producing aqueous iodide solutions. According to the disclosed method, iodine is electrolyzed in an aqueous catholyte and hydrogen iodide is formed.
Claims12
A method of producing hydrogen iodide comprising the steps of:
- providing an aqueous catholyte liquor containing a solubilizing amount of hydrogen iodide;
- providing an electrically conductive anolyte liquor;
- feeding iodine to the catholyte liquor;
- and
- passing an electrical current from an anode through said anolyte liquor and catholyte liquor to a cathode whereby to evolve hydrogen iodide.
2 more elements
A method of producing hydrogen iodide comprising the steps of:
- providing an aqueous catholyte liquor containing iodine;
- providing an electrically conductive anolyte liquor separated from said catholyte by a permionic membrane;
- and
- passing an electrical current from an anode through said anolyte liquor and catholyte liquor to a cathode whereby to evolve hydrogen iodide.
