Molecular weight: 206.02 

Structural Formula: 

 

Product performance: 

HEDP is an organic phosphonic acid corrosion inhibitor, can form into stable complex compound through chelating with Fe、copper、zinc and other metal ions, and can dissolve the oxides on the metals’ surfaces.

It can play a good role at scale and corrosion inhibition under 250℃, is also stable under high PH value, not easily to be dissolved and not easily to be resolved under thermal condition. When it is used complex together with other water treatment chemicals, will express ideal synergistic effect.
