• 化学的特性

  Mercuric Bromide is a crystalline solid

• 使用

  Medicine.

• 一般的な説明

  White rhombic crystals. Sensitive to light. Slightly soluble in water and denser than water. Severely toxic by inhalation and ingestion.

• 空気と水の反応

  Slightly soluble in water.

• 反応プロフィール

  MERCURIC BROMIDE is incompatible with acetylene, ammonia, chlorine dioxide, azides, calcium (amalgam formation), sodium carbide, lithium, rubidium, copper . Reacts with sodium azide to give mercury(II) azide, which is sensitive to shock, friction, and heat. Mixing with hydrazine salts in basic solution produced a heat or shock sensitive yellow precipitate [Annalen, 1899, 305, 191]. Reacts violently with chlorine trifluoride *with ignition often occurring.

• 危険性

  Toxic by inhalation, ingestion, and skin absorption; strong irritant.

• 健康ハザード

  TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

• 火災危険

  Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

• 安全性プロファイル

  A poison by ingestion, skin contact, and intraperitoneal routes. Vigorous reaction with indium at 35OC. Incompatible with sodmm and potassium. When heated to decomposition it emits very toxic fumes of Brand Hg. See also MERCURY COMPOUNDS and BROMIDES.

• 合成

  Five parts of Hg are covered with 60 parts of H2O and allowed to react at 50 °C (vigorous stirring) with four parts of Br2 , which is added dropwise as long as no permanent color is formed. The solution is then brought to a boil, filtered hot, and placed in an ice bath to induce crystallization. The salt is dried at as low a temperature as possible. Purification is by careful double or triple sublimation from a porcelain dish heated on a sand bath and covered with a Petri dish. When very high purity is required (e.g., for conductivity measurements), it may be necessary to re - peat the sublimation several times more.
  Hg + Br2 = HgBr2
  

• 職業ばく露

  This compound has applications in medicine.

• 輸送方法

  UN1634 Mercuric bromides, Hazard Class: 6.1; Labels: 6.1-Poisonous materials

• 純化方法

  Crystallise it from hot saturated ethanolic solution, dry and keep it at 100o for several hours under a vacuum, then sublime it. [Garrett J Am Chem Soc 61 2744 1939.] Its solubility in H2O is 0.6% at 20o, and 22% at 100o; in EtOH it is 30% at 25o; and in MeOH it is 69.6% at 25o. [Wagenknecht & Juza Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1109 1965.] POISONOUS.

• 不和合性

  Violent reaction with active metals; potassium, sodium. Store away from heat and light
