  • What is HEDP 1 hydroxy ethylidene 1 diphosphonic acid (HEDP)?
  • Home » Corrosion Inhibitors & Scale Inhibitor » HEDP/1-Hydroxy Ethylidene-1,1-Diphosphonic Acid Hydroxyethylidene Diphosphonic Acid (HEDP) is a highly efficient water treatment agent widely used as a scale and corrosion inhibitor. Packing: Liquid: 250kg/ drum, 1.25mt/IBC, or as customers’ requirement. Solid: 25kg/bag, customers’ requirement.
  • What are the properties of HEDP?
  • These properties allow the chemical to produce exceptional results in the production of detergent and the treatment of cooling water. HEDP has the chemical formula C2H8O7P2 and belongs to the phosphonate family, which can be further classified into chelating agents, scale inhibitors, stabilizers and corrosion inhibitors.
  • Is HEDP a phosphonate?
  • HEDP has the chemical formula C2H8O7P2 and belongs to the phosphonate family, which can be further classified into chelating agents, scale inhibitors, stabilizers and corrosion inhibitors. Phosphonates are salts and organic compounds of phosphoric acids. As salts, phosphonates can exist in both the primary (M' H2PO3) and secondary (M'2H PO3) forms.
  • Does HEDP cause equipment corrosion?
  • However, the remaining acid source (HEDP) is still the majority and will contribute to equipment corrosion. With the HEDPA-PER system, the degree of early-esterification in the blending equipment is relatively smaller, but the presence of ammonium prevents corrosion from the unreacted acid source (HEDPA).
