Description

Benzene, Diethenyl-, Polymer With Ethenylbenzene And Ethenylethylbenzene, Chloromethylated, 2-(Dimethylamino)Ethanol-Quaternized, Hydroxide is a quaternary ammonium functionalized anion exchange resin, a specialized polymer designed for selective ion capture and separation processes. This material is critical for applications requiring high purity and consistent performance in demanding chemical environments. It is primarily utilized by industries involved in water treatment, pharmaceutical purification, catalysis, and advanced chemical synthesis where reliable ion exchange capacity is paramount.

Application

• Water Purification & Demineralization: Used as an anion exchange resin in mixed-bed or separate-bed systems to remove anions, including nitrates, sulfates, and chlorides, from process water and ultrapure water systems.
• Pharmaceutical & Biotech Separation: Employed in the purification and isolation of active pharmaceutical ingredients (APIs), nucleotides, and other biomolecules through ion exchange chromatography.
• Catalysis & Chemical Synthesis: Serves as a solid-supported catalyst or reagent in organic synthesis, facilitating reactions such as esterification, alkylation, and hydrolysis.
• Metal Recovery & Hydrometallurgy: Applied for the selective recovery and concentration of precious or heavy metal anions from industrial waste streams and mining leachates.
• Sugar & Sweetener Processing: Used in the decolorization and deashing steps during the refining of sugar and high-fructose corn syrup.
• Nuclear Industry: Potentially used for the removal of specific radioactive anions from process solutions in nuclear fuel cycle operations.

Quality Control

Our anion exchange resins are manufactured under strict quality management systems. Each batch undergoes comprehensive testing to ensure critical parameters such as ion exchange capacity, moisture content, particle size distribution, and chloride content meet stringent specifications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee traceability and compliance with your process 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); ensure containers are sealed immediately after use to prevent moisture uptake, which can affect performance. Keep away from strong acids and oxidizing agents.
