ABSTRACT:
The invention relates to processes for removing chlorate salts from an aqueous alkali chloride solution employed in cation-exchange membrane electrolysis, comprising the steps of adding hydrochloric acid to an aqueous alkali chloride solution to form a reaction solution, and maintaining the absolute pressure of the reaction solution at a range not higher than 600 mmHg and not lower than the saturated vapor pressure of the solution in a decomposition vessel and/or feeding the reaction solution to the bottom portion of a decomposition vessel and causing the reaction solution to flow upward in the decomposition vessel.
