| General description: | Sulfamic acid, the monoamide of sulfuric acid, is a strong inorganic acid. It is generally used in chemical cleaning processes like removal of nitrites, carbonate- and phosphate-containing deposits. It is used as a raw material for the preparation of a synthetic sweetener i.e, sodium cyclohexylsulfamate. Sulfamic acid is an amino acid with sulfur and is mildly acidic. It acts as a green catalyst in the esterification reaction. |
