二過マンガン酸カルシウム

二過マンガン酸カルシウム 化学特性,用途語,生産方法

• 化学的特性

  violet or dark purple, deliquescent crystal(s); made by reacting KMnO4 and CaCl2; used in the textile industry, to sterilize water, and as a deodorizer [HAW93] [MER06]

• 使用

  Antiseptic, disinfectant, deodorizer; with CaF2 as binder for welding electrode coatings and fluxes.

• 一般的な説明

  Purple crystalline solid. CALCIUM PERMANGANATE is used as a disinfectant and deodorizer, in water purification, and for many other uses.

• 空気と水の反応

  Water soluble.

• 反応プロフィール

  CALCIUM PERMANGANATE is an oxidizing agent. Noncombustible but CALCIUM PERMANGANATE will accelerate the burning of combustible material. If the combustible material is finely divided the mixture may be explosive. Contact with liquid combustible materials may result in spontaneous ignition. Contact with sulfuric acid may cause fires or explosions. Mixtures with acetic acid or acetic anhydride can explode if not kept cold [Von Schwartz 1918 p. 34 ]. Explosions can occur when CALCIUM PERMANGANATE that has been treated with sulfuric acid comes in contact with benzene, carbon disulfide, diethyl ether, ethyl alcohol, petroleum, or other organic matter.

• 健康ハザード

  Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

• 火災危険

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

• 工業用途

  Calcium permanganate [Ca(MnO4)₂] is used in textile production, as a water-sterilising agent and in dental procedures.

• 安全性プロファイル

  Poison by intravenous route. See also CALCIUM COMPOUNDS, MANGANESE COMPOUNDS, and PERMANGANATES. A strong oxidant. May explode on contact with acetic acid or acetic anhydride. Ignites on contact with cellulose. Incompatible with hydrogen peroxide.

• 純化方法

  Crystallise it from water (3.3mL/g) by partial evaporation in a desiccator. It is deliquescent. Note that it loses oxygen more readily than the potassium salt. It is an oxidising agent.
