Abstract
The alkali metal perchlorates, e.g., sodium perchlorate or hydrate thereof, are continuously produced by continuously electrolyzing an aqueous solution electrolyte of a corresponding alkali metal chlorate in a single stage, while maintaining such electrolyte homogeneous and compositionally uniform over time by the continuous and simultaneous introduction of alkali metal chlorate and water thereto, and continuously directly separating desired alkali metal perchlorate from such solution of electrolysis.
