과산화칼륨 화학적 특성, 용도, 생산

화학적 성질
yellow amorphous mass; decomposes in water, evolving oxygen; oxidizing agent; used for bleaching, in oxygen generating gas masks [HAW93]
용도
Oxidizing agent, bleaching agent, oxygen- generating gas masks.
일반 설명
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.
공기와 물의 반응
Reacts exothermically with water (or moisture in the air) to give oxygen and a caustic solution, potassium hydroxide [NFPA 491M] .
반응 프로필
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].
위험도
Dangerous fire and explosion risk in con- tact with organic materials, strong oxidizing agent. Irritant to skin and tissue.
건강위험
Inhalation causes respiratory irritation. Ingestion causes severe burns of mouth and stomach. Contact with eyes or skin causes irritation and caustic burns.
화재위험
Behavior in Fire: Increases intensity of fire and can start fires when in contact with organic combustibles
Safety Profile
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, E INORGANIC.
