Sulfamic Acid – which is also known as amidosulphonic/amidosulphuric acid or sulphamidic acid produces sulfamates. Industrially, the sulfamic acid is produced by treating Sulphur-di-oxide with urea. This acid has wide applications like pharma, cleaning agent as remover of limescales and rust. Sulfamic acid is recommended compared to HCl as it is more safe.
However, if it gets mixed with bleaching agent, it will produce chlorine gas, which is a hazard. Other Industry applications include – dyes and pigments, herbicides, fire extinguisher and as a chloride stabilizer. The product is available in bags as a powder. It can be converted to acid with plain water to prepare acid applications.
