Cleaning agent
Aminosulfonic acid cleaning agents have a wide range of applications and can be used to clean boilers, condensers, heat exchangers, jackets, and chemical pipelines. Use it to remove scale from glass lined storage tanks, pots, open beer coolers, and beer barrels in breweries; Clean the evaporator of the enamel factory and the equipment of the paper mill; In terms of air conditioning, it can remove rust and scale from the cooling system and evaporative condenser; It can be used to remove seaweed and scale from seawater evaporators (distillation equipment), heat exchangers, and brine heaters on sea vessels; Can clean scale from copper pots, radiators, tableware washing mechanisms, silverware, flush toilets, ceramic tiles, food and dairy processing equipment; It can remove protein deposits on the steamer and deposits on disinfectant used in fresh meat, vegetables, and cheese processing plants. The US Department of Agriculture allows the use of sulfamic acid as an acidic cleaning agent in fresh meat, poultry, rabbit, and egg processing enterprises.
textile industry
Aminosulfonic acid can be used as an elimination agent for excess nitrite in the diazotization reaction in the dye industry, a color fixative for textile dyeing, and to form a fireproof layer on textiles. It can also be used as a cleaning agent and other additives in the textile industry.
Paper industry
Aminosulfonic acid can be used as a bleaching agent to reduce or eliminate the catalytic effect of heavy metal ions in the bleaching solution, ensuring the quality of the bleaching solution and reducing the oxidative degradation of fibers by metal ions. It can also prevent the peeling reaction of fibers and improve the strength and whiteness of pulp.
petroleum industry
Aminosulfonic acid can be used to remove blockages in oil reservoirs and improve their permeability. Injecting amino sulfonic acid solution into carbonate reservoirs can avoid salt deposition due to its easy reaction with reservoir rocks. The treatment cost is slightly higher than using hydrochloric acid, but the oil production is doubled. The United States uses 48.5% potassium hydroxyacetate and 3.4% amino sulfonic acid. A 0.1-3% aqueous solution of wetting agent is used to clean the gypsum scale layer in the oil well casing, and the treatment time is about 30 hours.
agriculture
Aminosulfonic acid and ammonium aminosulfonic acid were initially developed as herbicides. It is said that when they are directly applied to plants, they have the effect of coming into contact with toxic agents; And when applied to the soil, it has a male killing effect.
In the experiment conducted in Guangdong Province, China in 1978, the effect of sulfamic acid on male sterility in rice was found to be better than other salts. Spraying at a concentration of 0.05% to 0.5% resulted in a male sterility rate of 95% to 100%, but the effect was not stable enough and was harmful. The herbicide concentration of sulfamic acid is usually 75 g/L of the active ingredient.
electroplating solution
Aminosulfonic acid is commonly used for gold or alloy plating. The plating solution for gold, silver, and gold silver alloys contains 60-170 g of aminosulfonic acid per liter of water. The typical electroplating solution for silver plated women's clothing needles is 125 g of amino sulfonic acid per liter of water, which can obtain a very shiny silver plating surface. Alkali metal sulfates, ammonium sulfates, or sulfates can be used as conductive and buffering compounds in new aqueous gold plating solutions.
When recovering from nickel plating waste liquid, cation exchange resin is used for adsorption treatment, and then amino sulfonic acid is used to clean the resin, so that the adsorbed substance is desorbed and the resin is regenerated. For example, when processing 400 ppmNi electroplating wastewater, 50 ml of 150 g/L amino sulfonic acid is used to recover 2112 g/L of (NH2SO3) and 4148 g/L of NiSO4. When repairing nickel plated parts, nickel plating is required on the nickel surface, and 100 g/L amino sulfonic acid can be used for anodizing treatment. Before nickel plating, the nickel plating surface should be cleaned with 0.003-0.1 grams of amino sulfonic acid solution.
The content of amino sulfonic acid in copper plating solution is 3-20 L. The role of amino sulfonic acid is to make the coating fine and ductile, with high viscosity.
When iridium plating, NH2SO3H/Ir ≥ 7, the obtained iridium coating has no cracks, a thickness of 15 microns, and strong adhesion. This product exhibits good activity in automatic anti pollution equipment.
When plating rhodium rhenium alloy on silverware and electrical components, the electrolyte contains 100 g/L of amino sulfonic acid. When the coating thickness is ≤ 5 microns, it has high hardness and strong corrosion resistance, and the electroplating coating is very bright and beautiful.
The smooth and beautiful rhodium rhenium electroplated layer on brass has high hardness and corrosion resistance. The plating solution contains 100 g/L amino sulfonic acid, 50 g/L concentrated sulfuric acid, 2 g/L rhodium (such as sulfate), and 0.05 g/L rhenium [such as K3N (RuCl4H2O2) 2]. The deposition rate is 3-4 milligrams per ampere minute at 65 ℃ and 1-2 ampere per minute.
Italy has used lead aminosulfonic acid baths instead of fluorosilicic acid baths to reduce pollution. There are various uses in the anti-corrosion aluminum industry. The product has good luster and excellent processing performance.
Chemical synthesis analysis
Aminosulfonic acid is an inexpensive and stable solid acid in organic synthesis, which has good catalytic effect on esterification reactions with acid and does not corrode equipment. At the same time, it is also a raw material for manufacturing synthetic sweeteners, herbicides, flame retardants, preservatives, and so on. Products with a purity of over 99.9% can also be used as standard solutions for acids during alkaline titration.

DESCRIPTION
DESCRIPTION
Sulfamic acid is a weak organic acid typically used to clean limescale from ceramic tiles. Although it is nontoxic the dust can irritate the eyes and nose but will not cause tissue damage. These properties make it ideal for removing calcite deposits from copper specimens without damaging the copper. Vinegar is commonly used for this purpose but sulfamic acid is much faster. Hydrochloric acid can also be used and dissolves calcite much faster than sulfamic but it is more hazardous to use and if the copper contains arsenic it will produce a black tarnish on the copper that is very difficult to remove.
APPLICATION
APPLICATION
Cleaning agent
Sulfamic acid is used as an acidic cleaning agent and descaling agent sometimes pure or as a component of proprietary mixtures, typically for metals and ceramics. For cleaning purposes, there are different grades based on application such as GP Grade, SR Grade and TM Grade. It is frequently used for removing rust and limescale, replacing the more volatile and irritating hydrochloric acid, which is cheaper. It is often a component of household descalant, for example, Lime-A-Way Thick Gel contains up to 8% sulfamic acid and has pH 2.0–2.2, 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, and low toxicity. It forms water-soluble salts of calcium and ferric iron.
It also finds applications in the industrial cleaning of dairy and brewhouse equipment. Although it is considered less corrosive than hydrochloric acid, corrosion inhibitors are often added to the commercial cleansers of which it is a component. It can be used as a descalant for descaling home coffee and espresso machines and in denture cleaners.
