 Structural Formula: 

HEDPNa2 is an organophosphonic acid corrosion inhibitor. It can chelate with Fe, Cu, and Zn ions, and dissolve the oxidized materials. This salt has good scale and corrosion inhibition effects even under 250ºC.
HEDPNa2 is stable under high pH value, not easy to be hydrolyzed, not easy to be decomposed under normal light and heat condition. Its acid/alkaline and chloride oxidation tolerance are better than that of other organophosph-onic acids. 
HEDPNacan form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. It has good scale inhibition effects and obvious dissolution threshold effects. When used with other Water Treatment Chemicals, the synergistic effect is better.
