Gefahrenhinweise
Regulatory Information
Chemical: Sodium oxide (Na2O)
Sodium oxide (Na2O) is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Sodium oxide (Na2O) are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)
Status: Active Update: 21-09-2022 https://echa.europa.eu/registration-dossier/-/registered-dossier/22654
Sodium oxide (Na2O): Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.
Chemical Dangers
The solution in water is a strong base. It reacts violently with acid and is corrosive. Reacts violently with water. This produces sodium hydroxide. Decomposes at >400 °C. This produces sodium peroxide and sodium. Attacks many metals in the presence of water.

Ergänzende Hinweise
DefinitionA white solid formed by burning sodium in a deficiency of oxygen or alternatively by reducing sodium peroxide or sodium hydroxide with the requisite amount of sodium. It reacts violently with water to form sodium hydroxide and with acids to form solutions of their salts. Sodium monoxide forms cubic crystals. It dissolves in liquid ammonia to give a mixture of sodamide and sodium hydroxide.
