Product Introduction:
Amino Tris (Methylene Phosphonic Acid), more commonly referred to by its acronym ATMP, is an organic phosphonic acid compound with the molecular formula C3H12NO9P3 and molecular weight of 299.05. ATMP can be found as either a white crystalline powder or colorless to light yellow transparent liquid form and has excellent scale inhibition performance under 200degC. Production usually involves reacting ammonium chloride with formaldehyde and phosphorus trichloride; its chemical structure contains three methylphosphonic acid groups which form stable complexes with metal ions.
Amino Tris (Methylene Phosphonic Acid) exhibits exceptional chelating properties, effectively binding with calcium and magnesium ions found in water to inhibit mineral deposition and scale formation, especially calcium carbonate scale formation. ATMP also has low limit inhibition and lattice distortion effects to stop crystal growth from scale-forming salts; when present at higher concentrations in water it has a corrosion inhibitory effect, helping reduce corrosion of metal equipment or pipelines and thereby providing scaling prevention as well as corrosion inhibition benefits; ATMP can therefore widely be found being used at thermal power plants, refineries, oil field reinjection water systems as well as boiler water treatment systems to avoid scaling and corrosion to ensure equipment scaling and corrosion issues.
Amino Tris (Methylene Phosphonic Acid) can also be utilized as a metal ion chelating agent in textile printing and dyeing industries to effectively remove heavy metal ions in water, thus improving printing quality and increasing print durability. Furthermore, ATMP may also be applied as metal surface treatment agent for cleaning and protecting metal surfaces as well as improve washing results by chelating calcium and magnesium ions in hard water sources.
Amino Tris (Methylene Phosphonic Acid) offers many applications advantages; however, there are also potential drawbacks. For instance, its production process may produce pollution and waste; furthermore, under certain specific conditions hydrolysis reactions or reactions with other substances may occur, diminishing its useful effect. Furthermore, ATMP’s poor biodegradability can have adverse impacts on the environment – thus when using and handling ATMP it must adhere to safety and environmental regulations strictly in order to ensure its safe and sustainable application.

Amino Tris (Methylene Phosphonic Acid) has become an industry standard scale inhibitor for reverse osmosis membrane systems and circulating cooling water systems, saving 120,000 tons annually of water through reuse. By adding 8-12ppm ATMP, concentration rate increases threefold to sixfold and pitting rate decreases significantly (pitting rate decreased from 4x/year to 0.05x/year) when used together with zinc salts; using ATMP with polyacrylic acid pretreatment extends membrane pollution cycle from 15 days to 90 days – saving an additional 120,000 tons annually of water!
Amino Tris (Methylene Phosphonic Acid) is used extensively by the petrochemical industry as a scale inhibiting solution in oil production and water injection systems. When treating high sulfate formation water (SO42 -3800 mg/L) from Tarim Oilfield with 5ppm ATMP injection well scaling rates were reduced from 3mm/month to 0.2mm/month; its slowing effect in acid fracturing fluid also helps extend its action distance by 60% thereby increasing production rates significantly.
Amino Tris (Methylene Phosphonic Acid) can help the textile printing and dyeing industry control Fe3+-catalyzed decomposition of hydrogen peroxide during desizing and bleaching processes, increasing fabric whiteness by 2-3 levels. By adding 0.5% ATMP, dyeing rates of reactive dyes may increase by 15% while COD discharge of soap washing wastewater reduces by 52%; in soft water treatment processes using ATMP and NaAlO2 in combination, hardness levels from raw water (450 mg/L) to below 5mg/L significantly improving fabric feel significantly improving fabric feel significantly.
Amino Tris (Methylene Phosphonic Acid) is widely utilized as a cyanide-free electroplating solution additive. When applied to zinc-nickel alloy electroplating, its porosity can be reduced from 15/cm2 to 2/cm2, and salt spray resistance increased up to 1000 hours. Furthermore, pickling solutions containing ATMP have proven extremely successful at reducing residual iron on cold-rolled steel sheets by 80%; refining crystal size from 5mm down to 1mm while improving coating adhesion up to level 1 according to ASTM D3359 standards.
Amino Tris (Methylene Phosphonic Acid) has received both EFSA and FDA certification, and can now be found as an anti-calculus agent in oral care products. Experimental data show that adding 0.1% ATMP reduces dental plaque formation by 38% without irritating oral mucosa; replacing STPP with AMTP in laundry detergent reduces phosphorus content by 70% while still achieving detergency index values >95.
Amino Tris (Methylene Phosphonic Acid) stands out from traditional scale inhibitors with its exceptional environmental tolerance. Remaining stable between pH 2-12, it can withstand temperatures of 160degC (200degC for short duration), making it suitable for extreme working environments like geothermal power generation. After six months of circulation ATMP still retains 85% of its active ingredients while HEDP had decomposed completely under these same conditions; making ATMP irreplaceable as steam boiler water treatment agent.
Toxicological evaluation has revealed that Amino Tris (Methylene Phosphonic Acid) has an LD50 (rat oral) of >5000mg/kg, making it virtually non-toxic. Furthermore, its 28-day biodegradability (OECD 301D) rate of 78% surpasses organophosphorus product’s 35% biodegradation rate; also meeting EU REACH regulations with its 96h LC50 of 100mg/L for rainbow trout and 50mg/L limit on algae; all features that enable it to continue being used within EU Directive 2013/39/EU directive.
Functional Extending Properties HEDP obtained through hydroxylation modification of Amino Tris (Methylene Phosphonic Acid) has shown significant chlorine resistance enhancement, while its amination product NTMP increased corrosion inhibition efficiency of copper alloy by 50%. Furthermore, high purity ATMP (>=99.9%) has been used in semiconductor CMP polishing liquids to control surface roughness to below 1nm, as well as providing molecular designability to develop novel applications within fine chemicals.
Amino Tris (Methylene Phosphonic Acid) has undergone continuous technological evolution and application innovation, expanding from its original use of water treatment to other industries including new energy production and electronic materials. As environmental regulations become more stringent and industrial systems upgrade, Amino Tris will undoubtedly play a vital role in global sustainable industrial development processes.
