化学的特性
Sodium peroxide, Na202, is a fire-hazardous white powder that yellows when heated and causes ignition when in contact with water. Sodium peroxide is decomposed by heating, although this is not easily accomplished. It is stable in dry air; however, in moist air,or when acted on by water, it decomposes readily. It can be a powerful oxidizer and a powerful reducing agent, depending on conditions. Sodium peroxide is also used as a bleach, in medicine soap, and in the decomposition of minerals.

説明
Sodium peroxide has a molecular formula of Na2O2 and is an inorganic peroxide salt. It is a yellowish-white powder that turns yellow when heated. Sodium peroxide absorbs water and carbon dioxide from the air and is soluble in cold water. It is a strong oxidizing agent, is corrosive and can cause burns to the eyes and skin, and is also toxic by ingestion and inhalation. Sodium peroxide is water reactive and a dangerous fire and explosion risk in contact with water, alcohol, or acids. Sodium peroxide forms self-igniting mixtures with powdered metals and organic materials. It is incompatible with ethyl or methyl alcohol, glacial acetic acid, carbon disulfide, glycerin, ethylene glycol, and ethyl acetate. The four-digit UN identification number is 1504. The NFPA 704 designation is health 3, flammability 0, and reactivity 1. The 704 diamond has the prefix “oxy” in the white space at the bottom. It is used as bleach and as an oxygen-generating material for diving bells and submarines.
使用
Sodium peroxide historically was used to bleach wood pulp for the production of paper and textiles. It is mainly used for specialized laboratory operations, for example, the extraction of minerals from various ores. Sodium peroxide is used as an oxidizing agent and is used as an oxygen source by reacting with carbon dioxide to produce oxygen and sodium carbonate; it is thus particularly useful in scuba gear, submarines, and so on.
一般的な説明
A yellow-white to yellow granular solid. Mixtures with combustible material are readily ignited by friction, heat, or contact with moisture. May vigorously decompose under prolonged exposure to heat, causing the rupture of the containers.
