• 性質

  【Ⅰ】硝酸水銀(Ⅰ)：Hg2(NO3)2(525.19)．過剰の水銀を冷希硝酸に溶かすと得られる．水溶液からは二水和物(単斜晶系)を晶出する．密度4.8 g cm－3．水に易溶．水溶液は加水分解して淡黄色のHg(NO3)OHを析出する．空気による酸化を防ぐには水銀と共存させる．分析試薬，タンパク質の分析に用いる．有毒．[CAS 7782-86-7:HgNO3･H2O][CAS 14836-60-3:Hg2(NO3)2･2H2O]【Ⅱ】硝酸水銀(Ⅱ)：Hg(NO3)2(324.60)．水銀に過剰の熱硝酸を反応させて，溶液を濃縮すると0.5水和物が得られる．融点79 ℃．密度4.3 g cm－3．潮解性で，水で十分に希釈すると完全に酸化水銀と水銀に分解する．水溶液での保存は硝酸酸性とする必要がある．医薬品，有機化合物のニトロ化，酸化剤，フェルト製造に用いられる．有毒．[CAS 10045-94-0:Hg(NO3)2][CAS 7783-34-8:Hg(NO3)2･H2O][CAS 10045-94-0:Hg(NO3)2･nH2O]

• 反応性

  水銀の硝酸塩。一価および二価水銀の化合物が知られている。(1)硝酸水銀(Ⅰ)　冷希硝酸に水銀を過剰に溶かし、濃縮すると得られる無色の結晶。強く熱すると爆発する。加水分解しやすく、水溶液は酸性。有毒。冷暗所に貯蔵。タンパク分析に用いられる。(2)硝酸水銀(Ⅱ)　水銀に過剰の濃硝酸を加えて熱し、蒸発させると一（半）水和物が得られる。無色潮解性結晶。アンモニア水、アセトンに溶け、エタノール（エチルアルコール）に不溶。有毒。冷暗所に密栓して貯蔵。触媒、酸化剤としての用途がある。［中原勝儼］[補完資料] | 硝酸水銀（データノート1） | 硝酸水銀（データノート2）小学館　日本大百科全書(ニッポニカ) ）

• 化学的特性

  Mercuric nitrate is a white to yellowish crystalline solid with an odor like nitric acid. Normally exists as the hemihydrate or the dihydrate

• 使用

  Nitration of aromatic organic compounds, felt manufacture, mercury fulminate manufacturing.

• 一般的な説明

  A white crystalline solid. Toxic by inhalation, ingestion and/or skin contact. Prolonged exposure to fire or heat may result in an explosion. Produces toxic oxides of nitrogen when heated to decomposition. Used to make other chemicals and in medicine.

• 空気と水の反応

  Deliquescent. Soluble in a small amount of water. With much water or on boiling with water, an insoluble basic salt is formed.

• 反応プロフィール

  MERCURIC NITRATE is noncombustible, but, as an oxidizing agent, will accelerate the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided, an explosion may result. Light sensitive. Mixtures with alkyl esters may explode, owing to the formation of alkyl nitrates. Mixtures with phosphorus, tin(II) chloride, or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. Acetylene forms a sensitive acetylide when passed into an aqueous solution of MERCURIC NITRATE [Mellor 4:933. 1946-47]. Should not be mixed with alcohols as explosive mercury fulminates may be formed [Bahme 1961. p. 9]. Is violently reduced by hypophosphoric acid [Mellor 4:993. 1946-47]. Reacts with phosphine to give a yellow precipitate that explodes when heated or subjected to shock [Mellor 4:993. 1946-47].

• 危険性

  Dangerous fire risk in contact with organic materials. Very toxic.

• 健康ハザード

  Acute systemic poisoning may be fatal within a few minutes; death by uremic poisoning is usually delayed 5-12 days. Acute poisoning has resulted from inhaling dust concentrations of 1.2-8.5 mg/m 3 of air; symptoms inc lude tightness and pain in chest, coughing, and difficulty in breathing. Ingestion causes necrosis, pain, vomiting, and severe purging. Contact with eyes causes ulceration of conjunctiva and cornea. Contact with skin causes irritation and po ssible dermatitis; systemic poisoning can occur by absorption through skin.

• 安全性プロファイル

  Poison by ingestion, skin contact, intraperitoneal, and subcutaneous routes. A powerful oxidizer. Probably an eye, skin, and mucous membrane irritant. Reacts with acetylene to form the explosive mercury acetylide whch is sensitive to heat, friction, or contact with sulfuric acid. Reaction with ethanol forms the explosive mercury fulrmnate. Reaction with isobutene forms an unstable explosive product. Forms explosive mixtures with phosphine (heatand impact-sensitive), potassium cyanide (heat-sensitive), and sulfur. Violent reaction with phosphinic acid, hypophosphoric acid, unsaturated hydrocarbons, aromatics. Vigorous reaction with petroleum hydrocarbons. When heated to decomposition it emits very toxic fumes of Hg and NOx. See also MERCURY COMPOUNDS, INORGANIC; and NITRATES.

• 職業ばく露

  Mercuric nitrate is used in making other chemicals; in felt manufacture and in making mercury fulminate

• 輸送方法

  UN1625 Mercuric nitrate, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

• 不和合性

  A strong oxidizer. Reacts violently with combustibles, petroleum hydrocarbons; reducing agents; aldehydes, ammonia, ketones, phosphorus. Reacts with acetylene, alcohol, phosphine, and sulfur to form shocksensitive compounds. Aqueous solution attacks most metals. Vigorous and dangerous reaction with petroleum hydrocarbons. Incompatible with organic materials; acetylene, ethanol, phosphine, sulfur, hypophosphoric acid. Inorganic mercury compounds are incompatible with acetylene, ammonia, chlorine dioxide; azides, calcium (amalgam formation), sodium carbide; lithium, rubidium, copper. Decomposes in heat or on exposure to light, producing toxic fumes (mercury, nitrogen oxides)
