Sodium chlorite is alkaline with light hygroscopicity. It is easily soluble in water and alcohol. Under room temperature and normal storage condition, sodium chlorite has fine stability, which is between sodium hypochlorite and sodium chlorate. When heating up to 170℃, solid sodium chlorite and alkaline aqueous solution resolve into sodium chlorate and sodium hypochlorite. If contact with acid, it easily resolves and releases chloride dioxide gas. It easily explodes and burns when contact or clash with sawdust, organics and reducing substance.
Product Usage
Sodium chlorite is widely used in the production of chloride dioxide disinfectant. It is also used in the bleaching of cotton, flax, fiber and paper, metal surface treatment and water sterilization.
Storage & Transportation & Notes
Sodium chlorite is dangerous chemical product 5.1 category (UN NO: 1496). It should not be stored or transported with acid or reducing substance. It should be stored in cool, dry place, be away from fire, heat. Water, sand soil and dry powder extinguisher should be used to put out fire. Sodium chlorite dust has hormesis on respiratory organs, eyes and skin. If it splashes into eyes or on skin, please wash with clean water immediately. If it was ate by mistake, please drink saline solution or warm soapy water immediately. After spitting, transfer the person into hospital to receive treatment. Lethal dose is 10g.
