NICKEL NITRATE химические свойства, назначение, производство
Химические свойства
Nickel nitrate is a green powder.
Физические свойства
The hexahydrate forms emerald green monoclinic crystals; hygroscopic; density 2.05 g/cm3; isomorphous with corresponding cobalt salt; melts at 56.7°C; loses water on heating, decomposing to nickel oxide; very soluble in water; aqueous solution acidic; soluble in ethanol.
Использование
Nickel plating, preparation of nickel catalysts,
manufacture of brown ceramic colors.
Общее описание
NICKEL NITRATE is a green crystalline solid. NICKEL NITRATE is soluble in water. NICKEL NITRATE is noncombustible, but NICKEL NITRATE 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. Toxic oxides of nitrogen are produced in fires involving NICKEL NITRATE. NICKEL NITRATE is used in nickel plating and to make nickel catalysts for use in chemical manufacture.
Реакции воздуха и воды
Nickel nitrate, Ni(N03)2·SH20, is green, monoclinic, deliquescent crystals that are soluble in water and alcohol; a dangerous fife hazard and strong oxidant that is used in nickel plating and the preparation of catalysts and brown ceramic coloring.
Профиль реактивности
Green, crystalline material, toxic and carcinogenic. A powerful oxidizer, NICKEL NITRATE may cause a violent reaction with reducing materials (e.g., magnesium or aluminum powder, tin(II) chloride). Dangerous fire hazard, acts as oxygen carrier. When heated to decomposition NICKEL NITRATE emits highly toxic fumes of oxides of nitrogen [Lewis, 3rd ed., 1993, p. 915]. Complexes with tetrammine and tetrahydrazine are explosive [Bretherick, 5th ed., 1995, p. 1685].
Опасность
Dangerous fire risk, strong oxidizing agent.
Угроза здоровью
Inhalation of dust causes irritation of nose and throat. Ingestion causes vomiting. Dust irritates eyes and may cause dermatitis in contact with skin.
Профиль безопасности
Confirmed human
carcinogen. Poison by intravenous route.
Experimental reproductive effects. Mutation
data reported. A powerful oxilzer. When
heated to decomposition it emits very toxic
fumes of NOx. See also NICKEL
COMPOUNDS and NITRATES.
Возможный контакт
Nickel nitrate is used in electroplating,
in nickel catalyst production for making other chemicals
and the manufacture of brown ceramic colors.
Перевозки
UN2725 Nickel Nitrate, Hazard Class: 5.1;
Labels: 5.1-Oxidizer.
Несовместимости
A strong oxidizer. Incompatible with
strong acids; sulfur, combustibles, organics, and other easily
oxidizable materials. Noncombustible, but it 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.
Утилизация отходов
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations
governing storage, transportation, treatment, and waste
disposal.
