Product Description

CAS No. 23783-26-8

Molecular Formula: C2H5O6P

Molecular weight: 156

Structural Formula:

HPAA Properties：

HPAA is a highly effective and reliable chemical compound with many beneficial properties. It is chemically stable, meaning it is not easily broken down by acids or bases, making it safe for human use with no toxicity or pollutants. In addition, HPAA has superior zinc solubility and corrosion-inhibiting abilities that are five to eight times better than HEDP and EDTMP. When combined with low molecular polymers, the corrosion-inhibiting effect of HPAA can be significantly improved. All this makes HPAA an ideal choice for industrial applications requiring increased safety and efficacy.

HPAA Specification:

Items	Index

Usage：

HPAA is a versatile and reliable compound, making it ideal for cathode corrosion inhibitors in oilfield refill water systems. It has been popularly used in industries such as steel & iron, petrochemical, power plant, and medical fields with superior efficacy. When combined with zinc salt, the corrosion protection effect of HPAA can be significantly enhanced, making it an even more attractive option for these areas.
