Sodium peroxide (Na2(O2))
Exists as impurity (about 10%) in sodium peroxide, obtained by heat- ing sodium peroxide in oxygen, reacts with water to yield hydrogen peroxide, oxygen, and sodium hydroxide.
light yellow granular powder

UN 1504 5.1/PG 1
A severe irritant to shin, eyes, and mucous membranes. Dangerous fire hazard by chemical reaction; a powerfuloxidizing agent. Reacts explosively or violently under the appropriate conditions with water, acids, powdered metals, acetic acid, acetic anhydride, Al, (Al + CO2), aluminum + aluminum chloride, almond oil, (NH4)2S208, aniline, Sb, As, benzene, boron nitride, calcium aceqlide, charcoal, Cu, cotton wool, (KNO3 + dextrose), diethyl ether, fibrous materials + water, glucose + potassium nitrate, hexamethylene-tetramine, hydrogen sulfide, hydroxy compounds (e.g., ethanol, ethylene glycol, glycerol, sugar), magnesium, (Mg + CO2), MnO2, metals, metals + carbon dioxide + water, nonmetals (e.g., carbon, phosphorus, antimony, arsenic, boron, sulfur, selenium), nonmetal halides (e.g., diselenium dichloride, disulfur dichloride, phosphorus trichloride), organic matter, paraffin, K, silver chloride + charcoal, soap, Na, sodium dioxide, SCl, Sn, Zn, wood, peroxyformic acid, reducing materials. Will react with water or steam to produce heat and toxic fumes. To fight fire, use carbon dioxide or dry chemical. Combustible materials ignited by contact with sodium peroxide should be smothered with soda ash, salt or dolomite mixtures. Chemical fire extinguishers should not be used. If the fire cannot be smothered, it should be flooded with large quantities of water from a hose. When heated to decomposition it emits toxic fumes of Na2O. See also SODIUM HYDROXIDE and PEROXIDES, INORGANIC.
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.
SODIUM PEROXIDE(1313-60-6) reacts violently with reducing agents, combustible materials and light metals. Reacts exothermically and rapidly or even explosively with water to form a strong base (NaOH) and oxygen (O2) [Handling Chemicals Safely 1980 p. 854]. A mixture with ammonium persulfate can explode if subjected to friction (crushing in a mortar), if heated, or if a stream of gaseous carbon dioxide is passed over SODIUM PEROXIDE(1313-60-6) [Mellor 10:464 1946-47]. Reacts very vigorously with gaseous hydrogen sulfide; even in the absence of air, the reaction may be accompanied by flame [Mellor 10:132 1946-47]. An explosion results when gaseous carbon dioxide is passed over a mixture of SODIUM PEROXIDE(1313-60-6) with powdered magnesium [Mellor 2:490 1946-47] . Mixtures with acetic acid or acetic anhydride can explode if not kept cold [Von Schwartz 1918 p. 321]. Spontaneously flammable in contact with aniline, benzene, diethyl ether, or organic materials such as paper and wood. Mixtures with charcoal, glycerine, certain oils, and phosphorus burn or explode [Mellor 2:490 1946-47]. A mixture with calcium carbide (powdered) burst into flame when exposed to damp air and exploded when heated [Mellor 2:490 1946-47]. Decomposes, often violently in the presence of catalytic quantities of manganese dioxide [Mellor 2 Supp. 2:635 1961]. Mixing with sulfur monochloride leads to a violent reaction [Mellor 2 Supp. 2:634 1961]. Can react with and cause the ignition of fuels.
Air & Water Reactions
Reacts vigorously with water, large amounts react explosively [Haz. Chem. Data 1969. p. 201].
Dangerous fire and explosion risk in contact with water, alcohols, acids, powdered metals, and organic materials. Strong oxidizing agent. Keep dry. Irritant.
TOXIC; inhalation or contact with vapor, substance, or decomposition products may cause severe injury or death. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.
May ignite combustibles (wood, paper, oil, clothing, etc.). React vigorously and/or explosively with water. Produce toxic and/or corrosive substances on contact with water. Flammable/toxic gases may accumulate in tanks and hopper cars. Some may produce flammable hydrogen gas upon contact with metals. Containers may explode when heated. Runoff may create fire or explosion hazard.
Although sodium peroxide, Na202, is the principal product of the combustion of sodium, sodium monoxide is prepared commercially by carefully permitting sodium to react with a limited amount of oxygen according to the equation
If the sodium monoxide thus prepared is exposed to further dry oxygen or air, it is oxidized to the peroxide; this is the commercial method of preparing Na202 , the most important alkali peroxide,
