摘要

Sodium chloride in aqueous solution is converted to hypochlorite and chlorate by electrolysis in groups of cells whose electrodes are connected to a DC source in series circuit while the electrolyte is pumped through the cells in parallel flow between a distribution manifold and a collecting manifold connected to the cells by glass pipes. The manifold system consists of flangedly connected titanium pipes protected against electrolytic corrosion by electrical insulation between the sections and a small protective electrode having a platinum alloy surface and conductively connected to the anode pipe end adjacent the insulation.
