PROCESSO PARA PRODUCAO DE CLORATO DE METAL ALCALINO

摘要

The invention relates to a process for the production of alkali metal chlorates by electrolysis of alkali metal chloride. The electrolyte is prepared by addition of a crystal slurry having a dry content above 50 per cent by weight to the of alkali metal chloride depleted reaction solution flowing out from th eelectrolyster. The crystal slurry has been prepared by dissolving an alkali metal chloride in water whereafter the obtained water solution has been purified in a known manner and concentrated to the stated dry content.
