ペルオキシジカリウム 化学特性,用途語,生産方法
解説
過酸化カリウム．金属カリウムの液体アンモニア溶液に－50 ℃ で徐々に酸素を通じるか，または水酸化カリウムと過酸化水素の混合水溶液を真空中で濃硫酸上で蒸発させると二水和物が得られる．橙色の粉末．加熱によりK2Oと O2 に分解する．吸湿性があり，水と反応してKOHと O2 に分解する．酸化剤，漂白剤として用いられる．
化学的特性
yellow amorphous mass; decomposes in water, evolving oxygen; oxidizing agent; used for bleaching, in oxygen generating gas masks [HAW93]
使用
Oxidizing agent, bleaching agent, oxygen-
generating gas masks.
一般的な説明
A yellow granular solid. Mixtures of potassium peroxide and combustible material readily ignited by friction, heat or contact with moisture. Prolonged exposure to fire or heat may cause vigorous decomposition of the material and rupture of the container. Used as a bleach.
空気と水の反応
Reacts exothermically with water (or moisture in the air) to give oxygen and a caustic solution, potassium hydroxide [NFPA 491M] .
反応プロフィール
potassium peroxide is a strong oxidizing agent. Reacts readily with reducing agents, including most organic compounds, to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). A quantity left on a piece of paper in the open air usually starts a fire in the paper spontaneously in a few minutes [Freeman].
危険性
Dangerous fire and explosion risk in con-
tact with organic materials, strong oxidizing agent.
Irritant to skin and tissue.
健康ハザード
Inhalation causes respiratory irritation. Ingestion causes severe burns of mouth and stomach. Contact with eyes or skin causes irritation and caustic burns.
火災危険
Behavior in Fire: Increases intensity of fire and can start fires when in contact with organic combustibles
安全性プロファイル
Dangerous fire hazard
by spontaneous chemical reaction. It is a
very powerful oxidzer. Fires of this material
should be handled like sodurn peroxide
fires. Moderate explosion hazard by
spontaneous chemical reaction. Explodes on
contact with water, forming H2O2 and
KOH. Violent reactions with air, Sb, As, O2 ,
K. Vigorous reaction on contact with
reducing materials. On contact with acid or
acid fumes, it can emit toxic fumes.
Incompatible with carbon, diselenium
dichloride, ethanol, hydrocarbons, metals.
When heated to decomposition it emits
toxic fumes of K2O . See also PEROXIDES,
