Descrição

Descrição geral

Sulfamic acid (H₂NSO₃H) is a strong inorganic acid. It exists in zwitterionic form and neutral forms. Zwitterionic form is more stable than neutral form.
The ability of sulfamic acid/zinc powder to reduce nitrate to nitrogen gas under acidic condition has been utilized to denitrify nitrate-rich wastewater.

Aplicação

Sulfamic acid (H₂NSO₃H) may be used in the following studies:

• As a catalyst in the synthesis of aryl-14H-dibenzo[a.j]xanthenes.
• As a green catalyst for the liquid Beckmann rearrangement of ketoxime in dried acetonitrile.
• As a nitrogen source as well as an in situ activator of hydroxy groups in the direct iridium-catalyzed synthesis of primary allylic amines from allylic alcohols.
• Synthesis of polysubstituted quinolones.
