HOO 2-Phosphonobutane-1,2,4-Tricarboxylic Acid PBTCA 50% corrosion inhibitor

Product Detail

Molecular formula: C7H11O9P

Molecular weight: 270.13

Cas No.: 37971-36-1

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 and better than other normal organic phosphorus acid, especially under high temperature its antiscale property is far better than that of normal organophosphines.

PBTC can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.
