Abstract
Method for producing stable sodium chlorite by pelletization of granular sodium chlorite with metal salt or salts forming hydrates with water of hydration in the pellets being more than 5% of the anhydrous weight of the sodium chlorite. Pelletized sodium chlorite can be used to produce chlorine dioxide gas by passing a dilute mixture of chlorine gas and an inert gas through a bed of the pellets.
