Water treatment chemicals PBTCA Na4 CAS 40372-66-5

2-Phosphonobutane -1,2,4-Tricarboxylic Acid, Sodium salt (PBTC•Na4),CAS No. 40372-66-5, The molecular formula is C7H7O9P • Na4, with a relative molecular weight of 358. PBTC sodium salt Cas: 40372-66-5 is usually a colorless to pale yellow transparent liquid, or a white crystalline powder; PBTC-4Na has a low phosphorus content. Due to its structural characteristics of Phosphonic Acid and carboxylic acid, it has good scale and Corrosion Inhibition performance, which is superior to commonly used organic phosphonic acids. Especially at high temperatures, its scale inhibition performance is much better than commonly used organic phosphonic acids. It can improve the solubility of zinc, has good resistance to chlorine oxidation, and has good synergistic properties when compounded. Solids are prone to moisture absorption. PBTC sodium salt Cas: 40372-66-5 has a wide range of applications and superior performance in the formulation of efficient scale and corrosion inhibitors, and is also an excellent stabilizer for zinc salts.
