Description

Benzene, Diethenyl-, Polymer With Ethenylbenzene And Ethenylethylbenzene, Aminomethylated, Chloromethane-Quaternized, Hydroxide is a quaternary ammonium functionalized anion exchange resin, a key material for selective ion separation and catalysis. This specialized polymer offers high ion exchange capacity and chemical stability, making it critical for processes requiring precise purification and chemical recovery. It is essential for industries such as water treatment, pharmaceuticals, and chemical synthesis where the removal or exchange of specific anions is required.

Application

• Water Purification & Demineralization: Used as a strong base anion exchange resin in mixed-bed or separate-bed systems to remove anions like nitrates, sulfates, and chlorides from industrial process water and ultrapure water for electronics.
• Pharmaceutical Intermediate Purification: Employed in the isolation and purification of active pharmaceutical ingredients (APIs) and intermediates, particularly for the removal of acidic impurities and catalyst residues.
• Catalyst & Reaction Medium: Serves as a solid-supported phase-transfer catalyst or a basic catalyst in organic synthesis reactions, including alkylations and esterifications, facilitating easier product separation.
• Metal Recovery & Hydrometallurgy: Applied in the selective recovery of precious metals (e.g., gold, platinum) and other valuable anions from mining leachates and industrial waste streams.
• Sugar & Sweetener Processing: Utilized in the decolorization and deashing steps during the refining of sugar and the production of high-fructose corn syrup and other sweeteners.
• Chemical Manufacturing Separation: Integral to chromatographic separation processes and the purification of various organic acids, dyes, and specialty chemicals.

Quality Control

Our anion exchange resins are manufactured under a strict quality management system. Each batch is tested to ensure critical parameters such as ion exchange capacity, moisture content, particle size distribution, and chemical stability meet stringent specifications. Certificates of Analysis (COA) detailing these parameters are available upon request to support your quality assurance and regulatory compliance needs.

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) and a strong base; containers must be kept sealed to prevent moisture absorption and CO2 uptake from the air, which can reduce capacity. Isolate from strong acids and oxidizing agents.
