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.
Sulfamic acid is an amino acid with sulfur and is mildly acidic. It acts as a green catalyst in the esterification reaction.
Application
Sulfamic acid can be used as a catalyst in:
- Friedlander quinoline synthesis.
- Liquid Beckmann rearrangement for the synthesis of amides from ketoximes.
- The preparation of α-aminophosphonates via a three-component reaction between aldehydes, amines, and diethyl phosphite.
Features and Benefits
Meets A.C.S. reagent specifications.
