Product details

Pentasodium ethylene diamine tetramethylene phosphonic acid (EDTMP·Na₅, CAS 7651-99-2) is a highly effective sodium salt derivative of a phosphonic acid chelating agent, widely recognized for its exceptional performance in industrial water treatment, corrosion inhibition, and scale prevention. This compound, with the molecular formula C₈H₁₄N₂O₁₃P₅Na₅, is synthesized through the neutralization of ethylene diamine tetramethylene phosphonic acid (EDTMP) with sodium hydroxide, resulting in a stable, water-soluble salt.

EDTMP·Na₅ (CAS 7651-99-2) serves as a potent corrosion inhibitor in circulating cool water systems and boiler water treatment, where it forms stable complexes with metal ions (e.g., Ca²⁺, Mg²⁺, Fe³⁺) to prevent mineral deposits and oxidative damage. Its chelating properties make it essential in metal cleaning, oil drilling muds, and industrial effluent treatment, where it sequesters heavy metals like lead, copper, and nickel.

In water treatment applications, EDTMP·Na₅ (CAS 7651-99-2) is prized for its ability to disrupt scale formation caused by calcium carbonate and sulfate salts. It enhances the efficiency of ion exchange resins and reverse osmosis membranes by preventing fouling. Additionally, its low toxicity and environmental compatibility** position it as a preferred choice over traditional phosphate-based inhibitors in green chemistry initiatives.
