Description

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.

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.
