CAS: 23783-26-8
Synonyms: 2-hydroxy-2-phosphonoacetic acid; Hydroxyphosphonoacetic acid; HPAA;
Molecular Formula: C₂H₅O₆P
Molecular Weight: 156
Applications
HPAA is a versatile chemical with the following key applications:
Water Treatment: It serves as an effective cathodic corrosion inhibitor in oilfield refill water systems. In circulating water treatment systems, HPAA performs excellently as a corrosion inhibitor, and operators can also use it in combination with scale inhibitor ATMP-Na4. For optimal performance, plant operators often combine it synergistically with a high-efficiency biodegradable chelating agent like MGDA-Na3, which manages water hardness by sequestering scale-forming ions. Similarly, water treatment practitioners frequently pair HPAA with a high-performance scale and corrosion inhibitor such as PBTC.
Industrial Use: Widely used in steel, petrochemical, power plant, and medical industries.
Enhanced Performance: When combined with zinc salts, HPAA delivers superior corrosion inhibition.
Key Features:
Chemically stable and resistant to hydrolysis.
Non-toxic, safe to use, and environmentally friendly.
