Reliable HEDP Manufacturer Offering Corrosion & Scale Inhibitor Solutions

As a leading HEDP manufacturer, we provide HEDP Chemical – 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, a highly effective scale and corrosion inhibitor commonly used in water treatment applications. It is known for its strong chelating ability with metal ions like calcium and iron.

Process Manufacturing of HEDP

The manufacturing process of 1-Hydroxyethane-1,1-diphosphonic acid (HEDP), also known as Etidronic Acid, involves a controlled reaction between phosphorus trichloride (PCl₃), acetic acid, and phosphorous acid under specific conditions. Initially, acetic acid and phosphorous acid are mixed, and phosphorus trichloride is added slowly while maintaining the temperature and pH to prevent unwanted side reactions. This results in the formation of HEDP as the primary product. The reaction mixture is then subjected to purification processes like distillation and crystallization to obtain a high-purity acid. The final product is either presented as a colorless liquid or white crystalline powder, depending on the concentration and intended application. This process ensures that the resulting HEDP maintains strong chelating properties, excellent stability, and effective scale and corrosion inhibition, making it ideal for water treatment, detergents, and industrial cleaning applications.
