• 化学的特性

  Mercuric cyanide is an odorless, white crystalline solid; turns gray to dark brown when exposed to light

• 使用

  Mercuric cyanide finds veterinary application as a topical antiseptic for cats and other animals.

• 製造方法

  One part of HgO is digested for a few hours on a water bath with one part of Prussian blue and 10 parts of H2O. The mercuric cyanide crystals separate on evaporation of the solution.

• 一般的な説明

  Odorless tetragonal crystals or white powder. Toxic by inhalation (dust, and the hydrogen cyanide from decomposition) and by ingestion. Toxic oxides of nitrogen are produced in fires. It is used in medicine, germicidal soaps, photography, and in making cyanogen gas.

• 空気と水の反応

  Soluble in water. Gradually decomposed by water to give off hydrogen cyanide, a flammable poison gas.

• 反応プロフィール

  MERCURIC CYANIDE is rapidly decomposed by acids to give off hydrogen cyanide, a flammable poison gas. Decomposed in the light. May tend to explosive instability. Capable of violent reaction with oxidizing agents. Fusion with metal chlorates, perchlorates, nitrates or nitrites can cause a violent explosion [Bretherick 1979. p. 101].

• 危険性

  Toxic by ingestion, inhalation, and skin absorption.

• 健康ハザード

  Mercuric cyanide is a highly poisonous compound. Its components, mercury(II) and the cyanide ions, are both highly toxic. Its toxicity, however, is lower than that of sodium and potassium cyanides.
  Acute toxic symptoms from oral intake of this compound in humans are hypermotility, diarrhea, nausea or vomiting, and injury to kidney and bladder. Toxic symptoms may be manifested in humans from consuming 15–20 g of this compound. Lower doses may produce somnolence. An intraperitoneal dosage of 7.5 mg/kg was fatal to rats.
  LD50 value, oral (mice): 7.5 mg/kg.

• 火災危険

  Special Hazards of Combustion Products: Fumes from fire may contain toxic mercury and hydrogen cyanide.

• 安全性プロファイル

  Poison by ingestion, subcutaneous, intravenous, and intraperitoneal routes. Human systemic effects by ingestion: nausea or vomiting, hypermotility, dlarrhea, kidney changes, somnolence. Hydrolyzes to toxic fumes. A frictionand impact-sensitive explosive. It may initiate detonation of liquid hydrogen cyanide. Incompatible with fluorine, magnesium, sodium nitrite. When heated to decomposition it emits very toxic fumes of Hg, NOx, and CN-. See also CYANIDE and MERCURY COMPOUNDS.

• 職業ばく露

  Mercuric cyanide is used in medicine, germicidal soaps, photography and in making cyanogen gas

• 輸送方法

  UN1636 Mercuric cyanide, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

• 純化方法

  Crystallise it from water. The solubility in H2O is 8% at ~20o and 33% at ~100o; in EtOH it is 8% at ~20o and in MeOH it is 25% at ~20o. [Blitz Z Anorg Allgem Chem 170 161 1928.] POISONOUS.

• 不和合性

  Violent reaction with fluorine, magnesium, sodium nitrite, acids. Heating or contact with acid releases toxic mercury and flammable hydrogen cyanide gas. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides

• 廃棄物の処理

  Return to supplier for mercury recovery and deactivation.
