Product Description

CAS No. 40372-66-5

Molecular Formula: C7H7O9P•Na4Â Â Â Â Molecular weight: 358

Structure：

Properties:

PBTC•Na4 is an effective scale and corrosion inhibitor with a low content of phosphoric. Its unique structure, containing phosphonic acid and carboxylic acid groups, gives it superior scale inhibition properties even under high temperatures. This makes it far more effective than organophosphates. PBTC•Na4 can also improve the solubility of zinc salt, has good chlorine oxidation tolerance, and provides excellent composite synergy. It is also easy to deliquesce in its solid state.

Specification:

tems	Index
Appearance	Colorless to yellowish transparent liquid	White crystal powder
Active content (as PBTCA, % )	30.0 min	64.0 min
Active content (as PBTC•Na4, %)	40.0 min	85.0 min
Total phosphoric acid(PO43-%, )	10.5 min	22.5 min
Fe, mg/L	-	20.0 max
Density (20℃) g/cm3	1.35 min	-
PH (1% water solution)	9.0-12.0	4.0-6.0

Usage:

PBTC•Na4 is a highly effective composite scale and corrosion inhibitor that is widely used. It is an excellent stabilizer for zinc salt and can be used in high-temperature, hardness, alkaline, and high-concentration environments. When combined with other water treatment chemicals such as zinc salt, copolymer, organophosphine, and imidazole, PBTC•Na4 provides exceptional performance as a chelating agent and metal detergent.
