Welcome To Shree Sulphamic Chemical

Sulfamic acid, also known as amidosulfonic acid, amidosulfuric acid, amino sulphonic acid and sulfamidic acid, is a molecular compound with the formula H3NSO3. This colorless, water-soluble compound finds many applications.

Sulfamic acid melts at 205 °C before decomposing at higher temperatures to H2O, SO3, SO2, and N2. Sulfamic acid (H3NSO3) may be considered an intermediate compound between sulfuric acid (H2SO4), and sulfamide (H4N2SO2), effectively – though see below – replacing an – OH group with an – NH2 group at each step.

This pattern can extend no further in either direction without breaking down the – SO2 group. Sulfamates are derivatives of sulfamic acid.

Sulfamic acid is produced industrially by treating urea with a mixture of sulfur trioxide and sulfuric acid (or oleum).

The conversion is conducted in two stages:
OC(NH2)2 + SO3 → OC(NH2)(NHSO3H)
OC(NH2)(NHSO3H) + H2SO4 ? CO2 + 2 H3NSO3
