Abstract
Improved electrochemical processes for producing high purity grades of hydrogen iodide without developing cell fouling iodine solids through oxidation of iodide at the anode back migrating through ion exchange membrane into anolyte compartment. Two and three compartment electrochemical cells have anolyte solutions with chemical agents for oxidizing back migrating iodides to soluble iodine species to avoid build up of iodine solids on key cell components. Other embodiments include processes with undivided electrochemical cells fitted with hydrogen depolarized anodes, optionally operating electrogeneratively producing at least some of its own power requirements while simultaneously producing HI, or processes of making high purity HI with multi-phase aqueous/non-aqueous anolytes for solubilizing iodine solids as they develop in the anolyte compartment.
