Description

Benzene, Diethenyl-, Polymer With Ethenylbenzene, Chloromethylated, Trimethylamine-Quaternized, Hydroxide is a quaternary ammonium-functionalized anion exchange resin, a specialized polymer with strong basic properties. This material is engineered for high-performance ion exchange and catalysis, offering exceptional chemical stability and capacity in demanding environments. It is a critical component for industries requiring advanced separation, purification, and chemical synthesis processes, including water treatment, pharmaceuticals, and specialty chemical manufacturing.

Application

• Water Purification & Demineralization: As a strong base anion exchange resin for removing anions like nitrates, sulfates, and chlorides in ultrapure water (UPW) production for power generation, electronics, and pharmaceuticals.
• Pharmaceutical Intermediates: Used as a catalyst or reagent in the synthesis of active pharmaceutical ingredients (APIs), particularly in phase-transfer catalysis and purification steps.
• Chemical Synthesis Catalyst: Facilitates various organic reactions, including alkylations, esterifications, and hydrolyses, where a solid-supported strong base is advantageous for easy separation and recovery.
• Sugar & Sweetener Processing: Employed in the decolorization and deashing of sugar syrups and high-fructose corn syrup to improve purity and color.
• Metal Recovery & Hydrometallurgy: For the selective extraction and concentration of precious metals or the removal of toxic metal complexes from industrial wastewater.
• Biochemical Separations: Purification of antibiotics, amino acids, and other biomolecules through ion exchange chromatography in the biotechnology sector.

Quality Control

Our anion exchange resins are manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including ion exchange capacity, moisture content, particle size distribution, and chemical stability to ensure consistent performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We adhere to relevant industry guidelines to support applications in regulated environments.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and should be stored in a cool, dry, and well-ventilated area at room temperature (15-25°C). Ensure the container is kept sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide, which can degrade performance. Keep away from strong acids and incompatible materials.
