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.

Check Digit Verification of cas no

The CAS Registry Mumber 12034-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,3 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 12034-12:
47 % 10 = 7
So 12034-12-7 is a valid CAS Registry Number.
