Aminosulfonic Acid, Sulfamic Acid

Properties:

Aminosulfonic acid is also known as sulfamic acid. It is a white orthorhombic crystal and nonvolatile, nonhygroscopic, smell-less. The sulfamic acid has high stability at normal temperature. And it can maintain original quality for several years and is freely soluble in water and liquid ammonia, strongly acidic in water solution.

Aminosulfonic acid is slightly soluble in methanol, insoluble in ethanol, and ether. Characteristics of double functional groups of amino gen and sulphonic radical may go on chemical reaction with many matters. Its melting point is 205℃. And the decomposing temperature is 209℃.
