Description

Disodium (2-Ethylhexyl)Phosphate is an organophosphate salt widely utilized as a versatile surfactant and metal extraction agent. Its significance lies in its excellent chelating and surface-active properties, making it a critical component in formulations requiring precise control over metal ions and interfacial tension. This product is essential for industries such as metalworking, where it functions as a corrosion inhibitor and lubricant additive, and in chemical synthesis as a catalyst or intermediate.

Application

• Metal Extraction & Hydrometallurgy: Acts as a selective extractant for rare earth elements and transition metals in solvent extraction processes.
• Industrial Lubricants & Greases: Functions as an anti-wear additive and corrosion inhibitor, enhancing the performance and longevity of lubricating formulations.
• Surfactant & Emulsifier: Used in the formulation of specialty detergents, agricultural emulsions, and polymer dispersions due to its anionic surface-active character.
• Plastic & Polymer Stabilizer: Serves as a heat stabilizer and antioxidant in PVC and other polymer systems, improving material durability.
• Chemical Synthesis Intermediate: Employed in the production of more complex phosphate esters and as a catalyst in certain organic reactions.
• Water Treatment: Utilized as a scale and corrosion inhibitor in industrial cooling and boiler water systems.

Quality Control

Our Disodium (2-Ethylhexyl)Phosphate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) documenting assay, impurity profile, and physical parameters is provided with every shipment to guarantee traceability and compliance with your technical requirements.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
