Water treatment scale and Corrosion Inhibitor PBTCA 50% CAS 37971-36-1 PBTC

PBTC controls scale where halogen-based biocides or hypochlorite bleach are employed. Controls calcium scale formation in high stressed alkaline conditions. 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.

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


CAS No.  37971-36-1


Molecular Formula:   C7H11O9P            


Molecular weight: 270.13


Structural Formula:


e022adde4b0390d532b31a42a64c7883_pbtca



Properties:


PBTC has 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.

Usage:


PBTCA is a high 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, it is used as chelating agent and metal detergent.



Safety Protection:


Acidity, Avoid contact with eye and skin, once contacted, flush with water.
