Description

Tetradecapotassium [[(Phosphonatomethyl)Imino]Bis[Ethylene[(Phosphonatomethyl)Imino]Ethylenenitrilobis(Methylene)]]Tetrakisphosphonate is a highly specialized, multi-dentate chelating agent belonging to the aminopolyphosphonate family. This compound is engineered for superior sequestration of di- and trivalent metal ions, particularly calcium and magnesium, under demanding alkaline conditions. It is a critical performance chemical for industries requiring advanced scale inhibition and metal ion control in aqueous systems. Key sectors include industrial water treatment, detergent formulation, textile processing, and pulp & paper manufacturing.

Application

• Industrial Water Treatment: Primary application as a high-performance scale and corrosion inhibitor in cooling water, boiler water, and reverse osmosis systems, especially effective in high-pH and high-hardness environments.
• Detergent & Cleaner Formulations: Acts as a powerful builder and sequestrant to enhance cleaning efficiency by inactivating water hardness ions, preventing scale on machinery and fabrics.
• Textile Processing: Used in bleaching, dyeing, and scouring baths to sequester metal ions that can cause catalytic damage to fibers and uneven dyeing.
• Pulp & Paper Industry: Employed in bleaching sequences (e.g., hydrogen peroxide bleaching) to chelate transition metals (Fe, Mn, Cu) that degrade bleaching chemicals and cause brightness reversion.
• Oilfield Chemicals: Potential use in scale squeeze treatments and as a component in drilling fluid additives to control carbonate and sulfate scale formation.
• Personal Care Products: May be used in certain formulations as a chelating agent to stabilize products by binding trace metals.
• Industrial Cleaning: Effective in acidic and alkaline cleaning formulations for equipment and membrane cleaning to remove and prevent mineral scales.
• Agricultural Chemicals: Can be used as a stabilizer or compatibility agent in certain pesticide and fertilizer formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy. Keep away from strong oxidizing agents.
