EDTMP·Na5, Pentasodium Ethylenediamine Tetramethylene Phosphonate

Property:

EDTMP·Na₅ is pentasodium salt of ethylenediamine tetramethylene phosphonate. It is a neutral solid organophosphoric salt.

EDTMP·Na₅ is nitrogenous organic polyphosphonic acid, which is a part of the cathodic corrosion inhibitor. This pentasodium salt can be fully dissolved in water, innocuous, and no pollution to the environment. It has good chemical stability and thermal tolerance.

Pentasodium ethylenediamine tetramethylene phosphonate has a good 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 the calcium scale. EDTMP·Na₅ shows better scale inhibition effects to calcium sulfate and barium sulfate.
