Hodges, J R

This patent describes an electrolytic cell for the production of halogens or halates from their corresponding brine electrolytes, consisting essentially of: (a) an electrically conductive container for the electrolytes having a removable cover electrically insulated from a lower portion of the container; (b) an anode affixed to the cover and associated pairs of cathodes that are electrically connected to the lower portion of the container with the anode and cathodes being adapted to be operatively positioned within the container. At least a portion of the anode is overlapped by each adjacent cathode and the cathodes and anode are adapted to be immersed in the electrolytes. The anode consists essentially of: (i) a self supporting aluminum core, (ii) a sheath of metal from the titanium group completely covering at least that portion of the core that is disposed to be located within the interior of the container during cell operation, and (iii) an electroconductive coating of precious metal covering at least that portion of the anode and sheath that is overlapped by an adjacent cathode in (b); (c) means for applying a DC voltage between the anode and the lower portion of the container; (d) means for introducing brine electrolyte into the lower portion of the container, and (e) means for withdrawing from the container halogens or halates produced by electrolysis of the brine.
