60% 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid as scale and corrosion inhibition HEDP 

Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP)

CAS No. 2809-21-4 

Molecular Formula:   C2H8O7P2      Molecular weight: 206.02 

HS NO: 2931900090

UN NO. 3265

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℃.
