Product Introduction

Sulphamic Acid is also known as Sulfamic Acid, Amidosulfonic acid, Amidosulfuric acid, Minosulfonic acid, or Sulfamidic acid.

It is a molecular compound with the formula H3NSO3. It is a dry, non-volatile, non-hygroscopic, stable solid. It is soluble in water and forms a strongly acidic aqueous solution that is comparable in acidity to the common strong mineral acids, but it can be safely handled and stored in the dry form. The CAS Number for Sulfamic acid is 5329-14-6.

The main reason why Sulfamic Acids is used in oil and gas drilling is to reduce the pH of used extraction fluids and compounds prior to the disposal of these fluids. The benefits of using Sulphamic Acid is its ease of handling, solubility and low corrosiveness.

Sulfamic acid can also be used as an acidic cleaning agent, sometimes on its own or mixed with other products, typically for metals and ceramics. It is frequently used for removing rust and limescale.

Sulfamic acid is produced industrially by treating urea with a mixture of sulfur trioxide and sulfuric acid (or oleum). Sulfamic acid melts at 205 °C before decomposing at higher temperatures to water, sulfur trioxide, sulfur dioxide and nitrogen.
