What is Aluminum potassium disulfate dodecahydrate？
Potassium aluminum sulfate forms a solid, white powder at room temperature. The powder form, made up of crystals can be readily dissolved in water. Additionally, this material has a property known as astringency which is an ability to constrict body tissues, and restrict the flow of blood.
Potassium aluminum sulfate is chemical which conforms to the general formula KAl(SO4)2. Also known as aluminum potassium sulfate, its unique characteristics have made it an important compound to many industries.
The commercial production of potassium aluminum sulfate is typically accomplished by a method called hydrometallurgy. In this process, an aqueous solution of sulfuric acid is first used to extract alumina (solid Al2O3) from an ore called bauxite. This step, known as leaching, results in a solution which can then be reacted with potassium sulfate to form potassium aluminum sulfate. Another method of production involves converting aluminum sulfate to potassium aluminum sulfate by adding potassium sulfate. In addition to these chemical processes, potassium aluminum sulfate is also found occurring naturally in minerals such as alunite and kalinite.
What is aluminium ammonium sulfate？
Ammonium aluminium sulfate, also known as ammonium alum or just alum , is a white crystalline double sulfate usually encountered as the dodecahydrate, formula (NH4)Al(SO4)2·12H2O. It is used in small amounts in a variety of niche applications. The dodecahydrate occurs naturally as the rare mineral tschermigite.
Ammonium alum is not a major industrial chemical or a particularly useful laboratory reagent, but it is cheap and effective, which invites many niche applications. It is used in water purification, in vegetable glues, in porcelain cements, in deodorants and in tanning, dyeing and in fireproofing textiles.The pH of the solution resulting from the topical application of ammonium alum with perspiration is typically in the slightly acid range, from 3 to 5.
Ammonium alum is a common ingredient in animal repellent sprays.
The difference between them
Smell: ammonium alum has an ammonia smell, which is often called a smelly egg smell. Purpose: potassium alum is synthesized from industrial sulfuric acid and fertilizer ammonium bicarbonate, by strong acid and corrosive, not edible, contains excessive harmful heavy metals, contact skin easy to be absorbed or adsorption by human body,side effects, even in industry; ammonium alum can be used as food processing, fermentation powder processing, fried food processing, vermicelli processing, fruit and vegetable preservation.
Ammonium alum can be used for fermentation powder processing, fried food, jellyfish flooding, vermicelli processing, fruit and vegetable preservation and crisp protection, color protection, water purification and environmental protection, disinfection, rubber processing, leather, washing powder processing, feed processing, pencil production, potassium alum is different, the following is for you to introduce their differences: Potassium alum is synthesized from industrial sulfuric acid and chemical fertilizer ammonium bicarbonate, Being derived from being more acidic and corrosive, Not edible, Contains excessive heavy metals harmful to human body, Contact with the skin is easily absorbed or adsorbed by the human body, Side effects on the human body, In little use, even in
industry, Great damage to the equipment, At present, with the basic domestic production, Only a few small factories are still producing some sporadically, And then, to confuse the market,Although both ammonium alum and potassium alum are duplex salts produced from aluminum sulfate, They are all translucent white crystals, It is very difficult to distinguish from the appearance, The difference between ammonium alum and potassium alum is that the chemical name of ammonium alum is the aluminum ammonium sulfate, It is a compound salt produced by aluminum sulfate and ammonium sulfate, The chemical name of potassium alum is potassium aluminum sulfate, It is a compound salt produced by aluminum sulfate and potassium sulfate.They are very similar in appearance, but ammonium alum has a kind of ammonia flavor, which is often known.
