Amino tris(methylene phosphonic acid) Chemical Properties,Uses,Production
Amino tris(methylene phosphonic acid), its solid form is crystalline powder, soluble in water, hygroscopic, has excellent chelation, low threshold inhibition and lattice distortion. It has excellent scale inhibition below 200 ℃, low toxicity, good thermal stability, amino trimethylene phosphonic acid can be dissociated into six positive and negative ions in the water, and can form a stable chelate with a variety of metal ions such as iron, copper, aluminum, zinc, calcium, magnesium, etc. It has a more preferable scale inhibition effect on carbonate . And it has good synergy with the polyphosphate, polycarboxylate, nitrite. There are good inhibition when in 40mg/L.
It is used for power plants, refineries, petrochemicals, fertilizer plant cooling water, oil field injection water system,particularly suitable for hard high-calcium, low concentration multiple systems, such as power plants and high hardness high salinity, bad water quality conditions of the oil pipeline inhibitors,which may decrease the risk of corrosion and scaling of metal equipment and pipeline. In the textile printing and dyeing industry,Amino tris(methylene phosphonic acid) is used as a metal ion chelating agent, metal surface treatment agent.
The above information is edited by the chemicalbook of Tian Ye.
Amino tris(methylene phosphonic acid) is often used with other organic acid, polylactic acid or salt to form organic water treatment agents for circulating cooling water systems under a variety of different water quality conditions. The amount of 1~20mg/L is preferred; in an amount of 20~60mg/L when used as a corrosion inhibitor .
Amino tris(methylene phosphonic acid)is acidic, pay attention to labor protection, should avoid contact with eye and skin, once contacted, flush with plenty of water.
