ペルオキシジリチウム 化学特性,用途語,生産方法

• 化学的特性

  Lithium peroxide is a white crystalline solid or pale yellow powder which is thermodynamically stable at room temperature. The substance decomposes on heating to 195°C (the exact decomposition temperature is subject to dispute) with the formation of lithium oxide and oxygen. The decomposition forms the basis for one preparation of lithium oxide. High-purity lithium peroxide may be stored for long periods of time with no significant decomposition.
  The reaction of carbon dioxide and lithium peroxide is noted above. When lithium peroxide is exposed to the air, lithium carbonate is the final product. Dissolving pure lithium peroxide in water produces an alkaline solution containing lithium ions and hydroperoxide ions. The decomposition of the solution is typical in that oxygen is released on heating or in the presence of a catalyst. The water solubility of lithium peroxide decreases with increasing temperature.
  

• 使用

  At this time no important industrial uses of lithium peroxide are known. One interesting potential application is in the field of atmosphere regeneration for undersea and space applications, since the compound reacts with carbon dioxide to release oxygen: Li2O2+C02 -> Li2CO3 + 0.5O2.

• 製造方法

  Lithium peroxide is prepared industrially by the reaction of lithium hydroxide monohydrate with hydrogen peroxide which yields lithium hydroperoxide monohydrate.
  LiOH·H20 + H202 → LiOOH·H20+H20
  The hydroperoxide may be dehydrated by heating in a vacuum to yield the peroxide.
  2LiOOH·H20 → Li202+H202 + 2H20

• 一般的な説明

  A white powder or sandy yellow granular solid. Irritates skin, eyes and mucous membranes. Used to produce a supply of high-purity oxygen.

• 空気と水の反応

  Contact with water or moist air generates a large amount of heat and corrosive, alkaline lithium hydroxide [AAR 1991].

• 反応プロフィール

  Lithium peroxide is strongly basic and an extremely powerful oxidizing agent. Accelerates the combustion of other materials, especially organic materials, involved in a fire. Can ignite wood, paper, oil, clothing, etc. on contact. May react explosively with hydrocarbons (fuels). Exposure to heat in a closed container may result in a vigorous reaction that violently ruptures the container.

• 健康ハザード

  TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire may produce irritating and/or toxic gases. Toxic fumes or dust may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Runoff from fire control or dilution water may cause pollution.

• 火災危険

  May explode from friction, heat or contamination. These substances will accelerate burning when involved in a fire. May ignite combustibles (wood, paper, oil, clothing, etc.). Some will react explosively with hydrocarbons (fuels). Containers may explode when heated. Runoff may create fire or explosion hazard.

• 安全性プロファイル

  A powerful oxidizer and irritant to skin, eyes, and mucous membranes. A very dangerous fire hazard because it is an extremely powerful oxidizing agent. Will react with water or steam to produce heat; on contact with reducing materials, can react vigorously. See also LITHIUM COMPOUNDS, PEROXIDES, and PEROXIDES, INORGANIC.
