HEDP - Hebei Longke|Corrosion Inhibitor&Scale Inhibitor

Introduction to HEDP

1-Hydroxy Ethylidene-1,1-Diphosphonic Acid (HEDP) is a versatile organophosphonic acid compound that has gained significant attention in industrial water treatment and corrosion prevention. As a scale and corrosion inhibitor, HEDP is renowned for its ability to chelate with metal ions such as iron, copper, and zinc, forming stable complexes that prevent oxidation and scaling. Developed by Hebei Longke Water Treatment Co., Ltd., a leading Chinese manufacturer of water treatment chemicals, HEDP is a critical component in maintaining the efficiency and longevity of industrial systems.

Chemical Properties and Composition

HEDP, with the CAS No. 2809-21-4, has a molecular formula of C₂H₈O₇P₂ and a molecular weight of 206.02 g/mol. Its structural formula is represented as

The compound exhibits exceptional corrosion scale inhibitor properties, effectively preventing the formation of calcium carbonate and other mineral deposits in water systems. Its stability under high pH conditions and resistance to hydrolysis make it a preferred choice for applications involving extreme temperatures (up to 250℃). HEDP's ability to form hexa-element chelating complexes with calcium ions enhances its antiscale and threshold effects, ensuring long-term system performance.
