Product Description
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.
