ABSTRACT:
The invention relates to a process for electrolytic production of alkali metal chlorate where the demand of pH-adjusting chemicals is largely covered by integrated production of acid and alkali metal hydroxide. The process consists in electrolyzing a partial flow of chlorate electrolyte produced, in a cell provided with a separator, for producing a catholyte containing alkali metal hydroxide and an anolyte containing hydrochloric acid. The catholyte and the anolyte are used in alkalization and acidification in the chlorate process, thus significantly reducing the admission of impurities via externally produced chemicals.
