                 Ethylene Diamine Tetra (Methylene Phosphonic Acid) Sodium (EDTMPS)

CAS No. 1429-50-1                             Synonym: Dequest 2040
Molecular Formula: C6H12O12N2P4Na8                 Molecular weight: 612.13 
Properties:
EDTMPS is nitrogenous organic polyphosphonic acid, a part of cathodic corrosion inhibitor. Its corrosion inhibition is 3~5 times better than that of inorganic polyphosphate. It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. 
EDTMPS shows excellent scale inhibition ability under temperature 200℃. It dissociates into 8 positive-negative ions, thus can chelate with many metal ions to form polymer reticulation complex, to destroy the normal crystallization of calcium scale. It has better antiscale effects to calcium sulfate and barium sulfate.
