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℃.

Aminosulfonic acid can be used as amphoteric surfactants, metal parts cleaning agent, cyclamate sweetener, paper pulp bleacher, fire retarder, chlorine (sterilization) stabilizer, and electroplating additive.
Sulfamic acid can get away with surface oxide. So it can clean the boiler and sterilize bacterium in water, bleach fiber, wood, and paper, remove nitrate in tobacco. Aminosulfonic acid can also be used as raw material for pesticide intermediate.
Aminosulfonic acid cleaning agent has a wide range of applications. It can be used to clean scale and rust in boilers, condensers, heat exchangers, jackets, and chemical pipelines. The United States Department of Agriculture permits the use of sulfamic acid as an acid cleaner in fresh meat, poultry, rabbit, and egg processing facilities.
Aminosulfonic acid can be used as an eliminator of excess nitrate in diazotization reaction in dye industry and a fixative in textile dyeing. It can also form a fireproof layer on textiles, and sulfamic acid can also be used to make yarn cleaning agents and other auxiliaries in the textile industry.
Sulfamic acid can be used as a bleaching aid. It can reduce or eliminate the catalysis of heavy metal ions in the bleaching liquor, thereby ensuring the quality of the bleaching liquor, reducing the oxidation and degradation of metal ions on fibers, preventing the peeling reaction of fibers, and improving the strength and whiteness of pulp.
Aminosulfonic acid can be used to remove the plugging and improve the permeability of the reservoir. A sulfamic acid solution is injected into a carbonate-producing formation to double oil production.
Sulfamic acid and ammonium sulfamate were originally developed as herbicides. They are said to have an exposure effect when applied directly to plants; When it is applied to the soil, it has a male-killing effect.
Sulfamic acid is commonly used in gold or alloy plating. Italy has replaced the fluorosilicic acid bath with a lead sulfamate bath. This will reduce pollution.
