Description

Diethyl-N,n-Di-(2-Hydroxyethyl)Aminomethylphosphonat is a specialized organophosphorus compound that serves as a highly effective chelating agent and scale inhibitor. Its molecular structure, featuring phosphonate and tertiary amine groups, provides excellent sequestration of metal ions such as calcium, magnesium, and iron. This makes it a critical performance chemical for industries requiring superior water treatment, corrosion prevention, and process stabilization, particularly in cooling systems, boiler water treatment, and oilfield applications.

Application

• Industrial Water Treatment: Primary application as a high-performance scale and corrosion inhibitor in recirculating cooling water systems, boiler water, and desalination plants.
• Oilfield Chemicals: Used in drilling fluids, production chemicals, and squeeze treatments to control scale formation in downhole and surface equipment.
• Detergent & Cleaning Formulations: Acts as a builder and chelant to enhance cleaning efficiency by inactivating water hardness ions in industrial and institutional cleaning products.
• Pulp & Paper Processing: Employed as a chelating agent in bleaching sequences and to control metal-ion catalyzed decomposition of hydrogen peroxide.
• Textile Processing: Used to sequester metal ions in dyeing and bleaching baths, preventing stains and improving color fastness.
• Personal Care Products: Incorporated as a stabilizer and chelant in formulations such as shampoos and liquid soaps.
