説明
Magnesium nitrate has the molecular formula of
Mg(NO3)2 and the molecular weight of 148.3152 g/
mol.
Magnesium nitrate is prepared by the action of nitric
acid on magnesium carbonate, oxide or hydroxide:
MgCO3 + 2HNO3 ? Mg(NO3)2 + CO2 +H2O
Mg(OH)2 + 2HNO3 ? Mg(NO3)2 + 2H2O
The salt crystallizing at room temperature after
evaporation is the hexahydrate, Mg(NO3)2·6H2O. Two
stable hydrates are formed, the hexahydrate [CAS
number =13446-18-9] and the dihydrate, Mg(NO3)2·
2H2O [CAS number = 15750-45-5].
化学的特性
White crystals.Soluble in water and alcohol;
deliquescent.
化学的特性
Magnesium nitrate is white crystalline solid.
使用
In pyrotechnics; in the concentration of nitric acid.
定義
ChEBI: The inorganic nitrate salt of magnesium.
製造方法
The magnesium nitrate used in commerce has been synthesized in a variety of ways. The reaction between nitric acid and magnesium metal is one way and reaction with MgO is another. Magnesium hydroxide and ammonium nitrate also form the product but ammonia
一般的な説明
A white crystalline solid. Produces toxic oxides of nitrogen if heated to decomposition. Used in pyrotechnics.
空気と水の反応
Deliquescent. Water soluble.
反応プロフィール
Mixtures of Magnesium nitrate 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]. Noncombustible but 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. Prolonged exposure to fire or heat may result in an explosion. Magnesium nitrate has been reported to undergo spontaneous decomposition in dimethylformamide [Bretherick 5th ed., 1995]. Magnesium nitrate tends to behave as a strong oxidizer.
危険性
Dangerous fire and explosion risk in contact
with organic materials, strong oxidizing agent.
健康ハザード
Exposure can cause mild irritation to the mucous membranes. Symptoms may include coughing and shortness of breath. Ingestion of large doses may cause dizziness, abdominal pain, vomiting, bloody diarrhea, weakness, convulsions, and collapse. Contact with skin may cause irritation, redness, and pain.
安全性プロファイル
Probably a severe
irritant to the eyes, skin, and mucous
membranes. A powerful oxidizer. Violent
decomposition on contact with
dmethylformamide. When heated to
decomposition it emits toxic fumes of NOx.

COMPOUNDS.
職業ばく露
Magnesium nitrate is used in fireworks and in the production of concentrated nitric acid.
輸送方法
UN1474 Magnesium nitrate, Hazard Class: 5.1;

不和合性
A powerful oxidizer. Violent reaction
with dimethylformamide, reducing agents; combustibles,
fuels, organic and easily oxidizable matter
