ATMP or amino trimethylene phosphonic acid is an organic compound and having a high melting point of 215 °C and a density of 1.3 g/mL at 25 °C. ATMP acid plus, its sodium salts are broadly applied in for anti-scaling and descaling operations and recirculated cooling water systems for power station, oil field, central air-conditioning, refinery and etc. the Molecular Formula is N(CH2PO3H2)3. ATMP has excellent chelation. It can prevent the
Molecular Formula: N(CH2PO3H2)3
Molecular weight: 299.05
CAS No. 6419-19-8
creation of calcium carbonate in particular, in the water system. Also, it is able to reduce the corrosion of metal equipment and pipeline. ATMP has good chemical stability. It is hard to be hydrolyzed in water system due to a chemical bond between C_P. it forms Sustainable Complex with numerous metal such as Fe, Cu, Al, Zn,…. It is crystal powder in solid state and dissolvable in water, suitable for usage in winter and freezing districts but mostly it present in the colorless liquid state in marketing.
Chemical Structure Depiction:
ATMP make use of chelating factor in woven and dyeing industries and as a metal surface treatment agent. ATMP utilize with other organic acids, polylactic acid or salt to form organic water treatment agents for circulating cooling water systems.
It is used for petroleum addable, Textile auxiliary factors, chemical filtration.
Why Should You Treat Your Boiler Water with ATMP?
Boilers are very sentimental to the quality of water used. Presence of high degree of dissolved solids suspended particles, and sludge in boiler water is undesirable. They cause scaling of the boiler tubes thereby negatively touching its output. This results in the cost of production are high.
ATMP can improve boiler water conditions. By chelating action, it makes carbonates and sulfates remain in solution form. So no deposition will occur. Usually, the boiler can collapse when boiler tubes are heated beyond the melting point of the metal. It results from rising temperatures on the fireside as thick scales prevent effective heat transfer. Replacing a boiler is too expensive. And that’s why it’s better to treat boiler water.
Oilfield scaling such as limescale (calcium carbonate) may conduce to obstruction of pipes or slow down the fluid flow. Preventing this scaling in the oil and gas industry is essential in continuing high efficiency.
ATMP 50 is recommended for use as a scale inhibitor in refinery and thermal power plants.
It can store for ten months in room shady and dry place.
(1) ammonium chloride was added to the kettle, phosphorous acid aqueous solution and water, heated to 60 ℃ ~ 70 ℃ and efficiently shattered to completely dissolve the material; formaldehyde solution was then added dropwise, and the temperature control at 90 ℃ ~ 105 ℃, after finishing of the dropwise addition of formaldehyde, HCl generated was recovered by recovery of hydrochloric acid; turn fed to a distillation kettle after (2) incubation, slowly heated to 110 ~ 120 ℃ when omit unreacted ammonium chloride, formaldehyde, until no material was distilled off, the cooling water through cooling, discharge products.
In case of contact with eyes, clean immediately with plenty of water and seek medical advice Wear suitable protective clothing, gloves, and eye/face protection.
