Types of Aluminium Nitrate

01.

Aluminium Nitrate Crystal

Aluminium nitrate crystal is colorless rhombic crystal. It is oxidizing. Soluble in water, ethanol and CS2, aqueous solution is acidic, easy deliquescence. At 70℃, it melts into AI(NO3)3·6 H2O, decomposes to form basic salt [AI(NO3)3·3A1(OH)3·H20] at 135℃, and forms 4A1203·3N205· 14H2O at 140℃. When the temperature is higher than 200℃, aluminium nitrate crystal is completely decomposed into alumina.

02.

Aluminium Nitrate Nonahydrate

Aluminium nitrate nonahydrate is colorless crystal. It is easy to delix, melting point is 37.5℃, decompose at 150℃, easily soluble in water, alcohol, insoluble in ethyl acetate, aqueous solution is acidic, has strong oxidation, toxic, contact with flammable products can cause fire, and organic matter heating will burn and explode, irritating to the skin.Aluminium nitrate nonahydrate is mainly used in the manufacture of catalysts for organic synthesis, mordant for textile industry, oxidant, as a salting agent in the recovery of nuclear fuel by solvent extraction and for the manufacture of other aluminum salts.

Industrial Applications of Aluminium Nitrate

Leather

In order to chrome-tan leather, aluminum nitrate is occasionally combined with chrome salts. By stabilizing the collagen fibers in the hide, this technique increases the leather’s durability and resistance to degradation.

Chemical

Utilizing aluminum nitrate as a catalyst in the synthesis of polymers is among its most popular uses. Polymers are found in many different products, such as adhesives, textiles, and plastics. The synthesis of polyester fibers, polyethylene terephthalate (PET), and other polymers uses aluminum nitrate as a catalyst. It contributes to raising the reaction’s efficiency and lowering the energy needed to create the polymer. Furthermore, titanium dioxide and other chemicals can be produced using aluminum nitrate as a catalyst. White pigment titanium dioxide is used in many different products, such as paint, plastics, and paper. When producing titanium dioxide through the chloride process, which involves chlorinating ilmenite ore, aluminum nitrate is utilized as a catalyst.

Textiles

Aluminum nitrate has significant application in dyeing, where it serves as a mordant. Mordant is used to bind dyes to various materials. Aluminum nitrate in mordant is specifically used to bind the dyes with cotton. Thus, aluminum nitrate plays a crucial role in the cotton material dyeing process.

Water Treatment

In the water treatment industry, it acts as a flocculant, a chemical that makes suspended solids in water aggregate and sink to the bottom of the container. This facilitates the process of removing the solids from the water. In water treatment facilities, iron and manganese impurities—which can lead to discoloration and other issues—are eliminated with the use of aluminum nitrate. In order to get rid of heavy metals and other contaminants, it is also used in industrial wastewater treatment.

Aluminum Nitrate Production Process

Laboratory preparation method
Under heating conditions, dissolve aluminum in 57% nitric acid, boil the reaction solution slightly, and filter to remove impurities. The filtrate is acidified with nitric acid, evaporated and concentrated at a temperature not higher than 74°C until crystallization occurs. Cool and crystallize, filter, wash the crystals with ice water, dry in a sulfuric acid desiccator for a short time, and seal and package.

Industrial manufacturing method
Clean the metal aluminum plate with 10% caustic soda solution to remove surface oil stains, then rinse with tap water, then put it into the reactor, add a small amount of 1 (approximately 2 kg per 100 kg of aluminum flakes) mercury oxide as the oxidant, and then slowly Add dilute nitric acid (concentration of about 38%), keep excess aluminum during the reaction, and heat with steam to keep the reaction temperature at 110-115°C. After about 2 hours, the reaction is completed. The specific gravity of the reaction solution is 25-32 Be. After clarification and filtration, the clear liquid is sent to the evaporator and evaporated to 45-47 Be under reduced pressure. It is placed in a crystallizer for natural cooling and crystallization. After being taken out and mashed, it is dehydrated with a centrifuge. After drying, it is directly packed into barrels as the finished product.

Aluminum ash-nitric acid method
Add caustic soda solution and aluminum ash into the reactor to react to form sodium aluminate, then add nitric acid to react to form aluminum hydroxide and sodium nitrate. After the reaction solution is filtered, add nitric acid to dissolve the aluminum hydroxide to form Aluminum nitrate. The solution is then filtered, evaporated and concentrated, cooled and crystallized, and centrifuged to obtain the finished product of Aluminum nitrate.

Other methods
Aluminum nitrate is produced by directly reacting metallic aluminum with nitric acid. This method is simple and convenient, but the purity of the products produced is not high. This method is generally not used to produce Aluminum nitrate. Aluminum nitrate suitable for textile and other industrial uses is produced by metathesis of other industrially pure aluminum salts with aluminum nitrate, barium nitrate or calcium nitrate.

A: Because aluminium nitrate is a very strong oxidizing agent it is used for the processes such as tanning of leather, antiperspirants, corrosion inhibitors, in the process of extraction of uranium, in the refining of petroleum products, and of course as a nitrating agent.

Q: Why is aluminum important to the human body?

A: No known physiologic need exists for aluminum; however, because of its atomic size and electric charge (0.051 nm and 3+, respectively), it is sometimes a competitive inhibitor of several essential elements with similar characteristics, such as magnesium (0.066 nm, 2+), calcium (0.099 nm, 2+), and iron (0.064 nm, 3+).

Q: Is aluminum nitrate safe?

A: A skin and eye irritant; Causes vomiting and purging after ingestion; [CAMEO] Causes reproductive effects and weight loss in feeding studies in experimental animals; [HSDB] Not combustible, but as a strong oxidizer it may cause other materials to ignite.The more ions produced in the solution, the higher the electrical conductivity of the solution. Thus, aluminum nitrate will conduct electricity most strongly. This is the reason why distilled water which has a lesser number of ions present conducts lesser electricity compared to tap water.

Q: Is aluminium nitrate hazardous?

A: Hazardous in case of skin contact (irritant), of eye contact (irritant), of ingestion, of inhalation. Slightly hazardous in case of skin contact (permeator). Prolonged exposure may result in skin burns and ulcerations. Over-exposure by inhalation may cause respiratory irritation.Al(NO3)3 is an ionic compound that is made of a metal cation aluminum Al+3 and three nonmetal polyatomic anion NO3-. The net charge of Al(NO3)3 is equal to zero; one aluminum cation bonds with three nitrate anions.

Q: What happens when you mix aluminum nitrate and sodium hydroxide?

A: People have used aluminium compounds for medicinal purposes since the ancient Greeks, who used it as an astringent, for example to stop bleeding. Today, we use aluminium compounds to make vaccines more efficient and aluminium hydroxide is inter alia used to treat stomach ulcers.The water dissociates into proton which has +1 oxidation state and hydroxide ion which has -1 oxidation state. Therefore, the dissolution of aluminium nitrate in water gives the aluminium hydroxide and nitric acid.

Q: What are the risks of aluminum nitrate?

A: Severe irritation and burns Irritation Nose, throat and lung irritation with coughing, wheezing and/or shortness of breath Remove the person from exposure. Flush eyes with large amounts of water for at least 15 minutes. Remove contact lenses if worn.

Q: What happens when aluminium reacts with nitrate?

A: Hence, a cation of aluminium and a polyatomic anion of nitrate combine with each other to form a neutral salt compound having the aluminium nitrate formula. Thus, the chemical formula of Aluminium nitrate is given as Al(NO3)3 which is also the aluminium nitrate symbol.

Q: Does aluminum nitrate form a precipitate?

A: Aluminum nitrate is soluble in water. When it reacts with NaOH, double displacement reaction happens. A precipitate of Aluminium hydroxide gets formed, which is white in color. If NaOH is present in excess in the solution, then no precipitate will be formed.
