Dequest:2010
Molecular Formula:
C2H8O7P2 Molecular
weight: 206.02
Structural Formula:
Properties:
HEDP is an organophosphoric acid
corrosion inhibitor. It can
chelate with Fe, Cu, and Zn ions
to form stable chelating
compounds.It can dissolve the
oxidized materials on these
metals’ surfaces. HEDP shows
excellent scale and corrosion
inhibition effects under
temperature 250℃. 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, it 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, it can be used as
cleaning agent in electronic
fields and as additives in daily
chemicals.
