PBTC

1.PBTC 50 % (2-Phosphonobutane-1,2-4-Tricarboxylic Acid)

PBTC (ZEELCHEM™121)

CAS No. 37971-36-1

Molecular Formula: C7H11O9P

Molecular weight: 270.13

2.Usage

ZEELCHEM™121(PBTC) is a highly efficient agent as scale and corrosion inhibitor. It 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. It can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, its use as a chelating agent and metal detergent.ZEELCHEM™121(PBTC) has a low content of phosphoric, has 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.

ZEELCHEM™121(PBTC) usually use together with a zinc salt, copolymer, organophosphine, imidazole and other water treatment agents. When used alone, the dosage of 5-15mg/L preferred. Acidity, Avoid contact with eye and skin, once contacted, flush with water.

3.PROPERTIES

ZEELCHEM™121(PBTC) has a low content of phosphoric, has 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. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy. ZEELCHEM™121(PBTC) usually use together with a zinc salt, copolymer, organophosphine, imidazole and other water treatment agents. When used alone, the dosage of 5-15mg/L preferred.
