Sulfamic Acid

White rhombic crystal. Stable when dried, it is gradually hydrolyzed to ammonium bisulfate in solution. Soluble in 6.5 parts of water at 0℃, soluble in 2 parts of water at 80℃, sulfuric acid can reduce its solubility in water. Soluble in nitrogenous base, liquid ammonia, but also soluble in nitrogenous organic solvents such as pyridine, formamide and dimethylformamide, slightly soluble in acetone, ethanol and methanol, insoluble in ether. Strongly acidic, 25℃, the pH of 1% solution is 1.18. The relative density is 2.15. Melting point about 205℃(decomposition). It's stimulating

Mainly used as cleaning agent of descaling, clearing away oxidize surface, slightly corrosive to metal. It can be used in water treatment sterilization, bleach fiber, wood and paper; Acidification process, removing nitrite in tobacco, sludge treatment in oil mines; Manufacturing of Dyes, Pigments; Fire retardant; Curing agent in plastic industry; Chlorine Stabilization; Electroplating and Electro-refining; Raw material for pesticide intermediate, ramification of sulfamic acid etc..

(1) Main raw materials for sweetener production: 0.7 tons of sulfamic acid is consumed per ton of sweetener;

(2)  cleaning agent: used for metal cleaning, remove the oxide layer on the metal surface, the corrosion of metal is smaller than other inorganic acids in general, can be used for boiler cleaning and water treatment sterilization;

(3) Pulp bleaching agent: used for bleaching conversion of fiber, wood and paper, removing tobacco nitrite;

(4) curing agent, catalyst, disinfectant, flame retardant;

(5) Manufacture dyes and pigments;

(6) electroplating additives;

(7) In analytical chemistry can be used as a reference reagent for acid-base titration.

Usage:
Sulfamic acid is mainly a precursor to sweet-tasting compounds. Reaction with cyclohexylamine followed by addition of NaOH gives C6H11NHSO3Na, sodium cyclamate. Related compounds are also sweeteners, seeacesulfame potassium (Acesulfame K).
Sulfamates have been used in the design of many types of therapeutic agents such as antibiotics, nucleoside/nucleotide human immunodeficiency virus (HIV) reverse transcriptase inhibitors, HIV protease inhibitors (PIs), anti-cancer drugs (steroid sulfatase and carbonic anhydrase inhibitors), anti-epileptic drugs, and weight loss drugs.

1.Cleaning agent
Sulfamic acid is used as an acidic cleaning agent, sometimes pure or as a component of proprietary mixtures, typically for metals and ceramics. It is frequently used for removing rust and limescale, replacing the more volatile and irritating hydrochloric acid, which is however cheaper. It is often a component of householddescaling agents, for example, Lime-A-Way Thick Gel contains up to 8% sulfamic acid and pH 2 - 2.2, or detergents used for removal of limescale. When compared to most of the common strong mineral acids, sulfamic acid has desirable water descaling properties, low volatility, low toxicity. It forms water-soluble salts of calcium and ferric iron.
Importantly, sulfamic acid is preferable to use in household in comparison to hydrochloric acid for its intrinsic safety. If erroneously mixed with hypochlorite based products such as bleach, it does not form chlorine gas, where the most common acids would; the reaction (neutralization) with NH3, produces a salt as depicted in the section above.
It also finds applications in the industrial cleaning of dairy and brew-house equipment. Although it is considered less corrosive than hydrochloric acid, corrosion inhibitors are often added to commercial cleansers of which it is a component. Some of its domestic use, e.g. Easy-Off, for descaling include home coffee and espresso equipment and in denture cleaners.

2.Other uses
Catalyst for esterification process
Dye and pigment manufacturing
Herbicide
Coagulator for urea-formaldehyde resins
Ingredient in fire extinguishing media. Sulfamic acid is the main raw material for ammonium sulfamate which is a widely used herbicide and fire retardant material for household product.
Pulp and paper industry as a chloride stabilizer
Synthesis of nitrous oxide by reaction with nitric acid
The deprotonated form (sulfamate) is a common counterion for nickel(II) in electroplating.

3.Silver polishing
According to the label on the consumer product, the liquid silver cleaning product TarnX contains thiourea, a detergent, and sulfamic acid.
