질산수은(Ⅱ)(고체) 화학적 특성, 용도, 생산

• 화학적 성질

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

• 용도

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

• 일반 설명

  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.

• 공기와 물의 반응

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

• 반응 프로필

  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].

• 위험도

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

• 건강위험

  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.

• Safety Profile

  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.

• 잠재적 노출

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

• 운송 방법

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

• 비 호환성

  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)
