Organophosphoric Antiscale and Corrosion Inhibitors, Chelant

2-Phosphonobutane -1,2,4-Tricarboxylic Acid
(PBTC)

CAS No.: 37971-36-1

Molecular Formula: C7H11O9P

Molecular weight: 270.13

Structural Formula:

2-Phosphonobutane -1,2,4-Tricarboxylic Acid(PBTCA) Structural Formula

Properties:

2-Phosphonobutane -1 2 4-Tricarboxylic Acid has low content of phosphoric and structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. PBTCA can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.

Usage:

PBTC is a high efficient agent as scale and corrosion inhibitor.PBTC is the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer. PBTCA can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent.

2-Phosphonobutane -1,2,4-Tricarboxylic Acid is usually used together with zinc salt, copolymer, organophosphine, imidazole and other water treatment agents. When used alone, the dosage of 5-15mg/l is preferred.
