Basic Info

What is Amino Trimethylene Phosphonic Acid?

Chlorotrimethylenephosphonic acid, additionally known as amino trimethylene phosphonic acid (ATMP), has excellent chelating, low-limit inhibition as well as lattice distortion impacts. ATMP is manufactured from ammonium chloride, formaldehyde and phosphorus trichloride in one step.

ATMP has a steady C-P (carbon-phosphorus) bond and also is among the most typical representatives amongst organic acids. It can prevent the formation of scaling salts in water, specifically the development of calcium carbonate range. Amino trimethylene phosphonic acid is chemically secure in water and not conveniently hydrolyzed. When the concentration in water is high, it has good rust restraint impact.

Chlorine trimethylene phosphonic acid is made use of in thermal nuclear power plant, flowing cooling water in oil refineries, as well as oilfield reinjection water supply. It can contribute in reducing deterioration and also scaling of metal tools or pipelines. Amino trimethylene phosphonic acid is used as a steel ion chelating representative in fabric printing and also coloring industries, and also can also be used as a metal surface area treatment representative.

Amino Trimethylene Phosphonic Acid Uses

  1. Amino trimethylene phosphonic acid can lower deterioration as well as scaling of metal equipment or pipes.
  2. The strong is a crystalline powder, conveniently soluble in water, easy to take in dampness, simple to move and utilize, especially suitable for cool areas in winter.
  3. ATMP is made use of as a metal ion chelating representative in fabric printing and also dyeing sectors, and also can additionally be made use of as a metal surface therapy representative.
  4. As a result of the high purity of aminotrimethylene phosphonic acid ATMP, it can be used as a steel chelating agent and also steel surface treatment agent in the textile printing and also coloring industry.
  5. ATMP is chemically secure in water and also not quickly hydrolyzed. When the focus in water is high, aminotrimethylene phosphonic acid has a good rust inhibition result. ATMP is made use of in thermal nuclear power plant, distributing cooling water in oil refineries, as well as oilfield reinjection water supply.

Application of Amino Trimethylene Phosphonic Acid

ATMP has good chelating, low-limit inhibition and lattice distortion effects. Someone once tested that adding 1mg/L ATMP to water with a calcium hardness of 95mg/L can keep it stable for 24 hours at a temperature of 85 degrees. precipitation. According to the comparison of test data, ATMP is one of the best antiscaling agents for calcium carbonate in the methylene phosphonic acid type, so ATMP is especially used for inhibiting calcium carbonate scale. The concentration of ATMP as antiscalant alone is less than 10mg/l, the concentration of ATMP as corrosion inhibitor alone is more than 100mg/l; the concentration of ATMP and low molecular weight antiscalant is less than 5mg/l. Dosing mass concentration (active component) is generally 1-20mg/l. If it exceeds the above range, it will cause the formation of scale within a certain value. Usually in industrial use, in order to better exert its anti-scaling effect, it often works together with polycarboxylic acid.

ATMP is also used in thermal power plants, circulating cooling water in oil refining plants, and oil field reinjection water systems. Because ATMP has a corrosive effect on copper and its alloys, when using ATMP scale inhibitors, attention should be paid to the material of the circulation system, and azoles should be added Copper corrosion inhibitor can also be compounded with conventional chelating agents such as EDTA or NTA to achieve a synergistic and economical effect. ATMP can also compound with zinc salt, which can obviously improve the corrosion resistance of carbon steel. The optimal content of zinc in the formula is 30%-60%. Since zinc forms a complex with it, the solubilization and stability of zinc are added, so adding zinc The antiscalant of salt is not sensitive to the change of water quality, and the effect is more ideal.

In industrial use, due to certain specific environments, acidic substances are not allowed to be added. Usually ATMP is neutralized with sodium hydroxide to prepare ATMP sodium salt to achieve the purpose of scale and corrosion inhibition.

Water Treatment Agent

Amino trimethylene phosphonic acid (amino trimethylene phosphonic acid) solid is crystalline powder, easily soluble in water, easy to absorb moisture, and has good chelating, low-limit inhibition and lattice distortion effects. It has excellent scale inhibition effect below 200°C, low toxicity, good thermal stability, can dissociate into six positive and negative ions in water, and can chelate various metal ions such as iron, copper, aluminum, zinc, calcium, magnesium, etc. It forms a stable complex, especially for carbonate scale prevention. And it has good synergistic ability with polyphosphate, polycarboxylate and nitrite. It has good corrosion inhibition effect at 40mg/L.

Aminotrimethylene phosphonic acid (ATMP) is a methylene phosphonic acid compound, which is one of the earlier agents used in water treatment agents. Because it can form double five-membered ring chelates with Ca2+, Mg2+, Zn2+, Fe2+ and other metal ions in water, it has a good effect of inhibiting calcium carbonate scale and corrosion inhibition of carbon steel. ATMP is an organic phosphoric acid antiscalant, which is not easy to be hydrolyzed and can withstand temperatures above 100ºC. The dosage is relatively low, and it has better anti-scaling effect.
