過酸化亜鉛 化学特性,用途語,生産方法
外観
白色～わずかにうすい黄褐色, 結晶性粉末～粉末
溶解性
希塩酸に溶ける。水にほとんど不溶、アンモニア水に不溶。希酸により容易に過酸化水素を出して分解する。
用途
散剤、軟コウ剤として消毒、脱臭に用いる。
用途
ゴムの促進剤、合成エラストーマの硬化剤、創傷及び皮膚疾患の脱臭剤。
化学的特性
White powder containing 45–60%
ZnO2, balance ZnO. Decomposes rapidly above 150C. Decomposes in acids, alcohol, acetone;
insoluble in water but decomposed by it.
使用
Zinc peroxide is used as an accelerator in rubber-compounding, as a curing agent for synthetic elastomers, and as a deodorant for wounds and skin diseases.
一般的な説明
A white powder.
空気と水の反応
Slowly decomposed by water.
反応プロフィール
Zinc peroxide dissolves in dilute acid, liberating hydrogen peroxide [Merck 11th ed. 1989]. Noncombustible but accelerates the burning of combustible material. If the combustible material is finely divided, the mixture may be explosive. Mixtures with combustible material can sometimes be ignited by friction or contact with moisture.The hydrated material (of indefinite composition) explodes at 212°C. Mixtures with aluminum or zinc powder burn brilliantly [Mellor 1940. v. 4, 530].
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
Systemic toxicity is
similar to zinc oxide. Flammable when
SYN: ZINC SUPEROXIDE
212.. Can react.iolently with A. and Zn.
Very dangerous, wdl react with water or
steam to produce heat. Vigorous reaction
with reducing materials. When heated to
decomposition it emits toxic fumes of ZnO.
