Description

Octaammonium Tetrahydrogen [2,5,8,11,14-Pentakis(Phosphonatomethyl)-2,5,8,11,14-Pentaazapentadecane-1,15-Diyl]Bisphosphonate is a high-purity, multi-dentate chelating agent and scale inhibitor belonging to the class of polyamino polyphosphonates. This compound is engineered for superior performance in demanding water treatment and industrial cleaning applications where control of metal ions and mineral scale is critical. It is primarily utilized by formulators and process engineers in the water treatment, detergent, and oilfield chemical industries seeking reliable and effective sequestration and dispersion agents.

Application

• Industrial Water Treatment: As a highly effective scale and corrosion inhibitor in cooling towers, boilers, and reverse osmosis systems, particularly for controlling calcium carbonate, sulfate, and phosphate scales.
• Detergent & Cleaning Formulations: Acts as a powerful builder and sequestrant to inactivate water hardness ions (Ca²⁺, Mg²⁺), enhancing the cleaning efficiency of industrial and institutional detergents.
• Oilfield Production Chemicals: Used in squeeze treatments and production fluids to prevent scale deposition in downhole equipment and pipelines, ensuring uninterrupted flow.
• Pulp & Paper Processing: Serves as a chelant in bleaching processes and as a dispersant to control deposits, improving operational efficiency and product quality.
• Textile Processing: Employed as a sequestering agent to prevent metal-ion interference during dyeing, bleaching, and scouring operations, ensuring consistent color and fabric quality.
• Metal Surface Treatment: Functions in cleaning and pickling baths to control ferric and other metal ions, preventing redeposition and staining on metal surfaces.
