Process for manufacturing and using a more stable formulation of sodium chlorite

摘要

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.
