【CAS】 7651-99-2        

Molecular Formula:   C₆H₁₅O₁₂N₂P₄Na₅          Molecular weight:  546.13

Structural Formula:

Properties:

This is a neutral solid product, convenience in transport and usage in frigid situation, slight absorption of moisture. This product is nitrogenous organic polyphosphonic acid, which is a part of cathodic corrosion inhibitor. It can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal resistance. It shows excellent scale inhibition property under temperature 200℃. It can dissociate into 8 positive-negative ions, thus can chelate with more than two metal ions to form more than two polymer reticulation complex, the complex can be quickly dissolved in water to destroy the normal crystallization of calcium scale. EDTMPS shows better antiscale effects to calcium sulfate and barium sulfate.
