The aluminum nitrate It is the aluminum salt of nitric acid. Aluminum nitrate nonahydrate, at room temperature, appears as a colorless solid with the odor of nitric acid..
They are not combustible, but they can accelerate the combustion of combustible materials. If large amounts of aluminum nitrate are involved, or if combustible material is finely divided, an explosion may occur..
Prolonged exposure to fire or heat can lead to an explosion. When they come into contact with fire, they produce nitrogen oxides. Its uses include the refining of petroleum, and the dyeing and tanning of leather..
It is a white, water-soluble salt that most commonly occurs in its crystalline nonahydrate form (aluminum nitrate nonahydrate)..

Aluminum nitrate is a strong oxidizing agent.
Aluminum nitrate is deliquescent (it has the property of absorbing moisture from the air to form an aqueous solution). It is soluble in water. Its aqueous solutions are acidic.
Nitrates and nitrites are explosive compounds. Some of these substances can decompose explosively when heated or involved in a fire. They can explode from heat or contamination. Containers may explode when heated.
Special hazards from combustion products: toxic nitrogen oxides can form in a fire involving aluminum nitrate.
Nitrates and nitrites can act as extremely powerful oxidizing agents and mixtures with reducing agents or reduced materials such as organic substances can be explosive. React with acids to form toxic nitrogen dioxide.
In general, nitrate and nitrite salts with redox active cations (transition metals and the metals of group 3a, 4a and 5a of the periodic table, as well as the ammonium cation [NH4] +) are more reactive with organic materials and agents. gearboxes in ambient conditions.
Aluminum nitrate is an oxidizing agent. Mixtures with alkyl esters can explode. Mixtures with phosphorus, tin (II) chloride or other reducing agents can react explosively.
Humans are subject to nitrate and nitrite toxicity, with children being especially vulnerable to methemoglobinemia.
Ingestion of large doses of aluminum nitrate causes gastric irritation, nausea, vomiting, and diarrhea. Contact with dust irritates eyes and skin.
Nitrates and nitrites are widely used (and in very large quantities) as fertilizers in agriculture due to their willingness to break down and release nitrogen for plant growth and due to their solubility, which allows nitrate ions to be absorbed by the roots of the plant.
Nitrate compounds are also widely used as an industrial raw material when an oxidizing agent or nitrate ion source is required..
Aluminum nitrate is used in the manufacture of laboratory, cosmetic, and personal hygiene chemicals. In industry, it is used as an intermediate in the manufacture of other substances.
It is used in leather tanning, in antiperspirants, corrosion inhibitors, in uranium extraction, petroleum refining, and as a nitrating agent..
Aluminum nitrate nonahydrate and other hydrated aluminum nitrates have many applications. These salts are used to produce alumina for the preparation of insulating papers, in heating elements of cathode ray tubes and in the core laminates of transformers. Hydrated salts are also used for the extraction of actinidic elements..
Aluminum is ubiquitous, it is the most abundant metal in the earth's crust. Most human exposure comes from food. It is present in some pharmaceutical products. In industry it is widely used.
Aluminum inhibits bone remodeling, causing osteomalacia. It is believed to inhibit erythropoiesis, causing anemia.
Acute poisoning is rare. Soluble forms of aluminum have greater potential for toxicity than insoluble forms, due to their greater absorption..
Patients with kidney failure are prone to aluminum toxicity, either from aluminum in the dialysate or other exogenous sources, especially phosphate binders and aluminum-containing antacids..
Chronic exposure to aluminum dust can cause dyspnea, cough, pulmonary fibrosis, pneumothorax, pneumoconiosis, encephalopathy, weakness, incoordination, and epileptiform seizures..
Aluminum salts can cause irritation of the eyes and mucous membranes, conjunctivitis, dermatosis and eczema..
Although aluminum and its compounds have shown little evidence of carcinogenicity in humans, exposure to other substances involved in aluminum production has been associated with carcinogenicity..
Hazard statements of the Globally Harmonized System of classification and labeling of chemicals (GHS).
The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) is an internationally agreed system, created by the United Nations and designed to replace the various classification and labeling standards used in different countries by using consistent criteria globally..
The hazard classes (and their corresponding chapter of the GHS), the classification and labeling standards, and the recommendations for aluminum nitrate and for aluminum nitrate nonahydrate are as follows (European Chemicals Agency, 2017; United Nations, 2015; PubChem, 2017):
H272: May intensify fire; Oxidizer [Warning Oxidizing liquids; Oxidizing solids - Category 3] (PubChem, 2017).
H301: Toxic if swallowed [Acute Toxicity Hazard, Oral - Category 3] (PubChem, 2017).
H315: Causes skin irritation [Warning Skin corrosion / irritation - Category 2] (PubChem, 2017).
H318: Causes serious eye damage [Danger Serious eye damage / eye irritation - Category 1] (PubChem, 2017).
H319: Causes serious eye irritation [Warning Serious eye damage / eye irritation - Category 2A] (PubChem, 2017).
