化学的特性
Strontium peroxide is a lightcolored solid of good thermal stability. Commercial strontium peroxide contains about 85% SrO2 and 10% active oxygen.
使用
Strontium peroxide or strontium dioxide (SrO2) can cause fires or explode when heated and in contact with organic substances. It is used as both a reducing agent and an oxidizing agent.
製造方法
Like the other alkaline earth peroxides, it can be
prepared by reaction of the nitrate and sodium peroxide
in a cold solution:
Sr(NO3)2＋ Na2O2＋xH2O
SrO2·xH2O＋2NaNO3
The hydrated form is usually the octahydrate. If the
anhydrate is desired, the hydrated peroxide is dried
and then sintered at 350°C for 10 min or less:
SrO2·xH2O＋ heat→SrO＋SrO2＋H2O
一般的な説明
A white powder. Insoluble in water and slowly decomposed by water. Noncombustible, but accelerates the burning of combustible material.
空気と水の反応
Insoluble in water and slowly decomposed by water.
反応プロフィール
Strontium peroxide may explode from friction, heat or contamination. Accelerates burning when involved in a fire. May ignite combustibles (wood, paper, oil, clothing, etc.). If the combustible material is finely divided the mixture may be explosive.
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. A skin, eye, and mucous membrane irritant. Mixtures with organic materials readily ignite with friction or on contact with moisture. See also PEROXIDES and STRONTIUM COMPOUNDS.
