| | sodium superoxide Usage And Synthesis |
| Chemical Properties | Sodium superoxide, NaO2, is a yellow solid. | | General Description | A solid. Yellowish at room temperatures but may become white when cooled. Prolonged exposure to fire or heat may cause vigorous decomposition and the rupturing of the containers. | | Air & Water Reactions | Reacts with moisture and carbon dioxide in the air. Reacts vigorously with water to give oxygen and sodium hydroxide. | | Reactivity Profile | sodium superoxide violently decomposes above 250°C, evolving oxygen [Mellor 2 Supp. 2:639 1961]. An oxidizing agent. Reacts with carbon dioxide to give sodium carbonate and oxygen. Mixtures with combustible materials (most organic compounds) are readily ignited by friction, heat, or contact with moisture. | | Health Hazard | TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire may produce irritating and/or toxic gases. Toxic fumes or dust may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Runoff from fire control or dilution water may cause pollution. | | Fire Hazard | May explode from friction, heat or contamination. These substances will accelerate burning when involved in a fire. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react explosively with hydrocarbons (fuels). Containers may explode when heated. Runoff may create fire or explosion hazard. | | Safety Profile | An oxidizer. When heated to decomposition it emits toxic vapors of Na2O. |
