          CAS23783-26-8

          Alias: Hydroxyphosphonocarboxylic acid

          Molecular formula: C2H5O6P                Relative molecular mass: 156

          Structural formula:

          I. Product Property

          HPAA is chemically stable, hard to be hydrolyzed, hard to be destroyed by acid or alkali, safety in use, no toxicity, no pollution. HPAA can improve zinc solubility. Its corrosion inhibition ability is 5-8 times better than that of HEDP and EDTMP. When built with low molecular polymers, its corrosion inhibition effect is even better.

          III. Application scope and Usage

          HPAA is mainly used as cathode corrosion inhibitor in oilfield refill water system in fields such as steel & iron, petrochemcal, power plant and medical industries. When built with zinc salt, the effect is even better.

          V. Package and Storage

          It is normally packed in 30kg plastic drum and can be stored for one year in shady and dry place under room condition.
