Monosodium Of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid
(HEDP.Na)
CAS No. 29329-71-3
Molecular Formula: C2H7O7P2Na Molecular Weight: 228
Structure:
Properties:
HEDP Na is an organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, and Zn ions. It can dissolve the oxidized materials, and has good scale and corrosion inhibition effects even under 250℃.
HEDP.N2 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-oni acids.
HEDP.Na can form six-ring chelating compounds with metal ions in water system, Ca2+ in particuler. It has good scale inhibition effects and obvious dissolution threshold effects. When used with other water treatment chemicals, the synergistic effects is better. HEDO.Na is suitable for acidic scale inhibitor and detergent, can be used for metal surface treatment.
