2-Phosphonobutane -1,2,4-Tricarboxylic Acid
(PBTCA)
CAS No. 37971-36-1
Molecular Formula: C7H11O9P Molecular weight: 270.13
Synonyms: Dequest 7000, PBTC, Phosphonobutane Tricarboxylic Acid
Properties:
PBTCA has low content of phosphoric and 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.
