Sulfamic

acid, also known as amidosulfonic acid, amidosulfuric acid, aminosulfonic acid,

and sulfamidic acid, is a molecular compound with the formula H3NSO3. This

colorless, water-soluble compound finds many applications. Sulfamic acid melts

at 205 ?C before decomposing at higher temperatures to H2O, SO3, SO2, and N2. Sulfamic

acid (H3NSO3) may be considered an intermediate compound between sulfuric acid

(H2SO4), and sulfamide (H4N2SO2), effectively - though see below - replacing an

-OH group with an -NH2 group at each step. This pattern can extend no further

in either direction without breaking down the -SO2 group. Sulfamates are

derivatives of sulfamic acid.

Applications

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, see acesulfame potassium.

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.

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

household descaling agents, for example, Lime-A-Way Thick Gel contains up to 8%

sulfamic acid and pH 2 - 2.2,[11] 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.

Its

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.

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.

Silver polishing

According

to the label on the consumer product, the liquid silver cleaning product TarnX

contains thiourea, a detergent, and sulfamic acid.

Sulfamic Acid Information?

SULFAMIC

ACID is a dry, non-volatile, non-hygroscopic, odorless, white crystalline,

stable acid .It is moderately soluble in water and forms strongly acidic

aqueous solution that is comparable in acidity to the common strong mineral

acids but it may be easily handled and stored in the dry form. At room temperature

,dilute aqueous sulfamic acid solution is stable for a long time but rapid

hydrolysis occurs at elevated temperatures .Its solution is less corrosive

toward metals than other mineral acid. Because of advantages such as handling

ease, solubility and low corrosiveness, sulfamic acid is used for many

diversified applications.
