Monosodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP?Na) CAS No. 29329-71-3 Molecular Formula: C2H7O7P2Na Molecular weight: 228 Properties: HEDP?Na is an organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, and Zn ions. HEDP?Na can dissolve the oxidized materials, it has good scale and corrosion inhibition effects even under 250℃, it 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. HEDP?Na can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. Package and Storage: Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place. Safety Protection: Acidity, Avoid contact with eye and skin, once contacted, flush with water.
