    HEDP?ˆ?Na2

    Category: Chemicals / Detergents & Cleaning Placement Date: Sep 26, 2009 GMT

    Disodium of 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP?ˆ?Na2)
    CAS No. 7417-83-7 CubleK2012 Dequest 2016BD
    Molecular Formula: C2H6O7P2Na2 Molecular weight: 250

    Properties:
    HEDP?ˆ?Na2 is an organophosphonic acid corrosion inhibitor, it can chelate with Fe, Cu, and Zn ions, it 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 organophosphonic acids. HEDP?ˆ?Na2 can form six-ring chelating compounds with metal ions in water system, Ca2+ in particular. HEDP?ˆ?Na2 has good scale inhibition effects and obvious dissolution threshold effects. When used with other water treatment agents, the synergistic effects is better.
