• Detailed Description:

  CAS No. 2809-21-4
  
  Molecular Formula: C2H8O7P2
  Molecular weight: 206.02
  
  Propertiesof HEDP:
  HEDP is an organophosphoric acid
  corrosion inhibitor. HEDP can
  chelate with Fe, Cu, and Zn ions
  to form stable chelating
  compounds.HEDP can dissolve the
  oxidized materials on these
  metals' surfaces. HEDP shows
  excellent scale and corrosion
  inhibition effects under
  temperature 250 C. HEDP has good
  chemical stability under high pH
  value, hard to be hydrolyzed, and
  hard to be decomposed under
  ordinary light and heat
  conditions. Its acid/alkali and
  chlorine oxidation tolerance are
  better than that of other
  organophosphoric acids (salt).
  HEDP can react with metal ions in
  water system to form hexa-element
  chelating complex, with calcium
  ion in particular. Therefore,
  HEDP has good antiscale and
  visible threshold effects. When
  built together with other water
  treatment chemicals, HEDP shows
  good synergistic effects.
  The solid state of HEDP is
  crystal powder, suitable for
  usage in winter and freezing
  districts. Because of its high
  purity, HEDP can be used as
  cleaning agent in electronic
  fields and as additives in daily
  chemicals.
