• Detailed Description:

  2-Hydroxyphosphonocarboxylic
  Acid (HPAA)
  CAS No 23783-26-8
  Molecular Formula:
  C2H5O6P
  Molecular weight: 156
  
  Properties of HPAA:
  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.
  
  Specification of HPAA:
  Appearance Dark umber
  transparent viscous liquid
  Solid content % 47.0-50.0
  Phosphorous acid(as PO33-)%
  4.0 max
  Density (20 C)g/cm3 1.30 min
  
  pH(1% solution) 1.0-3.0
  
  Usage of HPAA:
  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.
  
  Package and Storage of HPAA:
  Normally In 250kg net Plastic
  Drum, IBC drum can also be used
  as required. Storage for one year
  in room shady and dry place.
