2-Phosphonobutane -1,2,4-Tricarboxylic Acid, Sodium salt
(PBTCA鈥a4)

CAS No. 40372-66-5

Molecular Formula: C₇H₇O₉P鈥a4 Molecular weight: 358

Structural Formula:

2-Phosphonobutane -1,2,4-Tricarboxylic Acid, Sodium salt (PBTC鈥a4)

Properties:

2-Phosphonobutane -1,2,4-Tricarboxylic Acid, Sodium salt has low content of phosphoric, its structure contains both phosphonic acid and carboxylic acid group, which enable its good scale and corrosion inhibition properties. Its scale inhibition property under high temperature is far better than that of organophosph-ines. 2-Phosphonobutane -1,2,4-Tricarboxylic Acid, Sodium salt can improve the solubility of zinc salt, has good chlorine oxidation tolerance and good composite synergy. The solid state is easy deliquescence.
