Molecular Formula: C7H11O9P
CAS No. 37971-36-1
Alias: PBTCA
Molecular weight: 270.13
Structural Formula:
CAS 37971-36-1 Water Treatment Chemical , PBTC 50% Phosphonobutane Tricarboxylic Acid
Properties & Use
PBTCA 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.
