과망간산 칼슘

과망간산 칼슘 화학적 특성, 용도, 생산

• 화학적 성질

  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]

• 용도

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

• 일반 설명

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

• 공기와 물의 반응

  Water soluble.

• 반응 프로필

  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.

• 건강위험

  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.

• 화재위험

  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.

• 공업 용도

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

• Safety Profile

  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.

• Purification Methods

  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.
