Description by Manufacturer

1.Name:1-Hydroxy Ethylidene-1,1-Diphosphonic Acid 2.CAS no.2809-21-4 3.Purity:50%,60%,90%

1.Product description

Chemical name:1-Hydroxyethylidene-1,1-Diphosphonic Acid(HEDP)

china water treatment chemicals

Abbreviation: HEDP

Molecular Formula: C2H8O7P2

Molecular Weight: 206

CAS Number: 2809-21-4

Application Notes: Noted for its excellent CaCO3 scale inhibition and chlorine stability.

2.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°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, 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.
