PBTC•Na4
ThFine
CAS No. 40372-66-5
2-Phosphonobutane -1,2,4-Tricarboxylic Acid, Sodium salt
CAS No. 40372-66-5
Molecular weight: 358
Molecular Formula: C7H7O9P•Na4
Structural Formula:
Properties:
PBTC•Na4 has low content of phosphorus, it has good scale and corrosion inhibition, because of its structural properties of phosphonic acid and carboxylic acid. Its scale inhibition under high temperature is superior to common organic phosphonic acid.
PBTC•Na4 can improve the solubility of zinc, and has good chlorine oxidation tolerance and good composite synergy. Its solid is easy to absorb moisture.
PBTC•Na4 is the most widely used in the combination of high efficiency scale and corrosion inhibitor.
Specification:

PH (1% water solution) | 9.0-12.0 | 4.0-6.0 |
Usage:
PBTC•Na4 is used as scale and corrosion inhibitor in circulating cool water system and oilfield refill water system, especially used together with zinc salt and copolymer.
PBTC•Na4 can be used in situations of high temperature, high hardness, high alkaline and high concentration index.
PBTC•Na4 is used as chelating agent and metal detergent in lavation fields.
PBTC•Na4 is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, 4 to 15 mg / L is preferred.
Package and Storage:
Liquid: Normally in 200L HDPE drum, 1000L IBC, or customers’ requirement.
Solid: 25kg inner liner PE bag, 1000kg woven bag, or customers’ requirement.
Storage for ten months in room shady and dry place.
