Pentasodium Salt of Ethylene Diamine Tetra (Methylene Phosphonic Acid) (EDTMP•Na₅)

CAS No.  7651-99-2

Molecular Formula: C₆H₁₅O₁₂N₂P₄Na₅         Molecular weight: 546.13

Structural Formula:

Properties:

EDTMP•Na₅ is a neutral solid product. It is nitrogenous organic polyphosphonic acid, which is a part of cathodic corrosion inhibitor. EDTMP•Na₅ can be fully dissolved in water, innocuous and none pollution to environment, has good chemical stability and thermal tolerance. EDTMP•Na₅ has good scale inhibition property under temperature 200℃. EDTMP•Na₅ 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. EDTMP•Na₅ shows better scale inhibition effects to calcium sulfate and barium sulfate.

EDTMP•Na₅ can be used as scale and corrosion inhibitor for circulating water and boiler water system, chelating agent in non-cyanide electroplating, water-softening agent in dyeing industry, etc.

The solid state EDTMP•Na₅ is slightly easy to deliquescence, convenient in transportation and suitable for usage in winter and freezing districts.
