Product Description

2-Phosphonobutane -1,2,4-Tricarboxylic Acid, Sodium salt

CAS No. 40372-66-5
Molecular Formula: C7H7O9P•Na4 Molecular weight: 358


PBTC•Na4 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. PBTC•Na4 can improve the solubility of zinc salt, has good chlorine oxidation tolerance and good composite synergy. The solid state is easy deliquescence.
