Description

Disodium 2-(Phosphonatooxy)Acrylate is a specialty organophosphorus compound that serves as a highly effective scale and corrosion inhibitor. This unique molecule combines the chelating power of a phosphonate group with the reactivity of an acrylate moiety, offering superior performance in demanding aqueous systems. It is a critical raw material for formulators in the water treatment, detergent, and oilfield industries seeking advanced multifunctional additives.

Application

• Industrial Water Treatment: A key component in cooling water and boiler water treatment formulations for its excellent calcium carbonate and calcium phosphate scale inhibition properties.
• Detergent & Cleaning Agents: Used as a builder and sequestrant in industrial and institutional cleaning products to enhance cleaning efficiency and prevent scale deposition on surfaces and equipment.
• Oilfield Chemicals: Employed in scale inhibitor formulations for squeeze treatments and production chemicals to control mineral scaling in downhole and topside facilities.
• Pulp & Paper Processing: Acts as a dispersant and chelant in pulp bleaching and papermaking processes to improve efficiency and product quality.
• Textile Auxiliaries: Utilized in dyeing and finishing baths to sequester metal ions that can interfere with processes and affect color fastness.
• Personal Care Products: Incorporated as a stabilizing and chelating agent in certain cosmetic and personal care formulations.

Quality Control

Our Disodium 2-(Phosphonatooxy)Acrylate is manufactured under a stringent quality management system. Every batch is analyzed to ensure it meets precise chemical and physical specifications, including assay, impurity profile, and solution characteristics. A comprehensive Certificate of Analysis (COA) documenting purity, identity, and key parameters is provided with each shipment to guarantee consistency and support your quality assurance protocols.

Storage

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