Sulfamic acid, also known as amidosulfonic acid, amidosulfuric acid, aminosulfonic acid, andsulfamidic acid, is a molecular compound with the formula H3NSO3. This colorless, water-soluble compound finds many applications.
Applications Sulfamic acid is used as an acidic cleaning agent, sometimes pure or as a component of proprietary mixtures, typically for metals and ceramics. It is frequently used for removing rust and limescale, replacing the more volatile and irritating hydrochloric acid. It is often a component of householddescaling agents or detergents used for removal of limescale. When compared to most of the common strong mineral acids, Sulfamic acid has desirable water descaling properties, low volatility, low toxicity and is a water soluble solid forming soluble calcium and iron-III salts. Its also finds applications in the industrial cleaning of dairy and brew-house equipment.
Although it is considered less corrosive than hydrochloric acid due to its lower pKa, corrosion inhibitors are often added to commercial cleansers of which it is a component. It is possible that the amino group could act as a ligand under certain circumstances, as does the chloride ion for Fe-III, when hydrochloric acid is used in rust removal.
▪ Catalyst for esterification process
▪ Dye and pigment manufacturing
▪ Ingredient in Denture Tablets
▪ Coagulator for urea-formaldehyde resins
▪ Ingredient in fire extinguishing media. Sulfamic acid is the main raw material for Ammonium sulfamate which is a widely used herbicide and fire retardant material for household product.
▪ Pulp and paper industry as a chloride stabilizer
▪ Synthesis of nitrous oxide by reaction with nitric acid
▪ In household cleaning chemical products such as Cameo.
The deprotonated form (sulfamate) is a common counterion for Nickel(II) in electroplating.
