ビスチオシアナト水銀(II) 化学特性,用途語,生産方法

• 外観

  白色～わずかにうすい黄色, 粉末

• 溶解性

  エタノールに溶けにくく、水にほとんど溶けない。塩酸(1+3)及びシアン化カリウム溶液に溶けやすい。

• 用途

  分析試薬(塩化物イオンの吸光分析等)。

• 化学的特性

  Mercuric thiocyanate is an inorganic chemical substance. It is a stable solid at room temperature, and depending upon the purity, it appears as odourless white crystalline powder or grey. It is insoluble in water and denser than water and sinks in water. The solubility in alcohol and boiling H2O and in KSCN solution is higher, in ether lower. Decomposes with swelling on heating to 165°C. On decomposition, mercuric thiocyanate releases hazardous substances such as cyanide vapours, vapours of mercury, oxides of nitrogen (NO, NO2), and oxides of sulphur (SO2, SO3). Mercury thiocyanate has limited uses in chemical synthesis.

• 使用

  For Pharaoh's serpents (fireworks); intensifier in photography.

• 空気と水の反応

  Insoluble in water.

• 反応プロフィール

  MERCURIC THIOCYANATE decomposes into its elements at about 165°C. Burns readily in air to generate a coil of cohesive ash resembling a serpent (hence used in a firework: Pharaoh's serpents). Swells up to many times its original volume if heated [USCG, 1999]. Soluble in dilute hydrochloric acid [Merck]. Incompatible with strong oxidizing agents.

• 危険性

  Highly toxic by ingestion, inhalation, and skin absorption.

• 健康ハザード

  Mercuric thiocyanate causes severe eye and skin irritation with possible burns and causes digestive and respiratory tract irritation with possible burns. It may impair fertility, may cause harm to the unborn child, is harmful if inhaled, may cause allergic skin reaction, may cause kidney damage, may cause CNS effects, is light sensitive, and is a severe marine pollutant. Contact with acids liberates very toxic gas. The target organs include kidneys, CNS, reproductive system, eyes, and skin.

• 安全性プロファイル

  A poison by ingestion and intraperitoneal routes. Moderately toxic by skin contact. Thermally unstable and decomposition may be vigorous. When heated to decomposition it emits very toxic fumes of Hg, NOx, SOx, and CN-. See also MERCURY COMPOUNDS and CYANATES.

• 合成

  A Hg(NO3)2 solution, acidified with a few drops of HNO3, is treated with the stoichiometric amount of KSCN solution. The resultant crystalline precipitate is suction-filtered and washed with H2O. The product may be recrystallized from hot H2O or alcohol. Yield 80%.
  Hg(NO3)2 + 2 KSCN = Hg(SCN)2 + 2KNO3
  

• 職業ばく露

  Mercury thiocyanate is used in photography and fireworks.

• 輸送方法

  UN1646 Mercury thiocyanate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

• 純化方法

  Recrystallise it from H2O, and it can give various crystal forms depending on conditions. Its solubility in H2O is 0.069% at 25o, but is more soluble at higher temperatures. It decomposes to Hg above 165o. Poisonous. [Mason & Forgeng J Phys Chem 35 1121 1931, Birckenbach & Kolb Chem Ber 68 919 1935.]

• 不和合性

  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. Mercury thiocyanate is sensitive to heat; expands to many times its original volume and then decomposes at freezing/melting point forming toxic fumes of sulfur oxides, mercury cyanide, and nitrogen oxides. Contact with acid or acid fumes causes release of toxic mercury and cyanide vapors. Incompatible with chlorine, reducing agents such as hydrides, sulfides

• 廃棄物の処理

  Small amounts may be destroyed by alkaline hydrolysis. Admixture with alkali can be followed by soil burial. Larger quantities can be disposed of by incineration in admixture with acetone or xylene and using effluent gas scrubbing. Do not reuse empty container; proper disposal required.
