SULFAMIC ACID

Sulfamic Acid is an inorganic solid acid formed by replacing the hydroxyl group of sulfuric acid with an amino group. Its chemical formula is NH2SO3H, molecular weight is 97.09, and it is generally a white, odorless oblique square shaped crystal with a relative density of 2.126 and a melting point of 205 ℃. It is soluble in water and liquid ammonia, and at room temperature, as long as it remains dry and does not come into contact with water, the solid Sulfamic Acid is non hygroscopic and relatively stable. The aqueous solution of sulfamic acid has the same strong acidity as hydrochloric acid, sulfuric acid, etc., so it is also known as solid sulfuric acid. It has the characteristics of non volatility, no odor, and low toxicity to the human body. Dust or solution is irritating to the eyes and skin and can cause burns. The maximum allowable concentration is 10 mg/m3. Sulfamic Acid can be used to synthesize herbicides, fire retardants, sweeteners, preservatives, metal cleaning agents, etc. It is a common chemical raw material.
