Alias: Pentasodium ethylenediamine tetramethylene phosphonate 

Molecular Formula: C₆H₁₅O₁₂N₂P₄Na₅ 

Relative Molecular Mass: 546.13

1. Performance and Application

EDTMP·Na₅ is a neutral nitrogen‑containing organophosphonate and an anodic corrosion inhibitor. It is miscible with water, non‑toxic and pollution‑free, featuring excellent chemical stability and heat resistance. It maintains good scale‑inhibiting performance at 200 ℃. Dissociating into 8 positive and negative ions in aqueous solution, it can chelate with multiple metal ions to form large‑molecule network complexes, which disperse stably in water and destroy the normal crystal growth of calcium scale.

1. EDTMP sodium salt exhibits excellent scale inhibition effect against calcium sulfate and barium sulfate scale.
2. Solid product has slight hygroscopicity, convenient for transportation and application in cold environments.
3. Used as corrosion and scale inhibitor for circulating water and boiler water, complexing agent for electroless plating, water softener in printing & dyeing industry, cooling water treatment for power plants, etc.
