定義
ChEBI: An inorganic nitrate salt having copper(2+) as the couterion.
-
一般的な説明
Obtained as a trihydrate and as a hexahydrate. Both are blue crystalline solids. Used in medicine, as an insecticide, in chemical analysis, in making light sensitive papers. Toxic oxides of nitrogen are produced in fires involving Copper dinitrate.

空気と水の反応
Deliquescent. Water soluble.

反応プロフィール
Mixtures of Copper dinitrate 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]. A finely divided mixture of potassium ferrocyanide and Copper dinitrate exploded when dried at 220°C [Chem. Abst. 77:1343 (1972)]. Noncombustible, but Copper dinitrate will accelerate the burning of combustible materials. If large quantities of the material are involved in a fire or the material is finely divided, an explosion may result. Prolonged exposure to fire or heat may result in an explosion.

危険性
Oxidizer, causes violent combustion or
explosion with organic materials.
-
健康ハザード
Inhalation causes irritation of throat and lungs. Ingestion of large amounts causes violent vomiting and purging, intense pain, collapse, coma, convulsions, and paralysis. Solutions irritate eyes; contact with solid causes severe eye surface injury and skin irritation.
-
安全性プロファイル
Moderately toxic by
ingestion. A severe eye and skin irritant.
Potentially explosive reaction above 22OOC
with ammonium or potassium
hexacyanoferrate(I1). Reaction with
ammonia + potassium amide gives explosive
product. Violent reaction with acetic anhydride. May ignite on prolonged contact
with paper. Concentrated solutions may
ipte in contact with tin or aluminum foil.
Used as a fungicide, herbicide, and as a
catalyst component in solid rocket fuel.
When heated to decomposition it emits
toxic fumes of NOx. See also COPPER
COMPOUNDS and NITRATES.

職業ばく露
Cupric nitrate is used as an insecticide, in paint, varnish, enamel, and in wood preservatives. Metal compounds are often used in “hot” operations in the work-place. These may include, but are not limited to, welding, brazing, soldering, plating, cutting, and metallizing. At the high temperatures reached in these operations, metals often form metal fumes which have different health effects and exposure standards than the original metal compound and require specialized controls.

輸送方法
UN1479 Oxidizing solid, n.o.s., Hazard Class: 5.1; Labels: 5.1-Oxidizer, Technical Name Required.
-
純化方法
Crystallise it from weak aqueous HNO3 (0.5mL/g) by cooling from room temperature. The anhydrous salt can be prepared by dissolving copper metal in a 1:1 mixture of liquid NO2 and ethyl acetate and purified by sublimation [Evans et al. J Chem Soc, Faraday Trans 1 75 1023 1979]. The hexahydrate dehydrates to the trihydrate at 26o, and the anhydrous salt sublimes between 150 and 225o, but melts at 255-256o and is deliquescent.
-
不和合性
A strong oxidizer. Aqueous solution is acidic; incompatible with bases. Violent reaction with potassium hexacyanoferrate; ammonia and potassium amide mixtures; acetic anhydrides, cyanides, ethers. Forms explosive materials with nitromethanes, sodium hypobromite; acetylene; chemically active metals, such as potassium, sodium, etc. May ignite on contact with aluminum foil or tin. Risk of spontaneous combustion with combustibles (wood, cloth, etc.) organics, or reducing agents and readily oxidizable materials. Attacks metals in the presence of moisture.

廃棄物の処理
Copper-containing soluble wastes can be concentrated through the use of ion exchange, reverse osmosis, or evaporators to the point where copper can be electrolytically removed and sent to a reclaiming firm. If recovery is not feasible, the copper can be precipitated through the use of caustics and the sludge deposited in a chemical waste landfill. Add slowly to water; stir in excess soda ash. Let stand, then neutralize. Decant solution and flush to sewer; landfill sludge
