Description

2-Propenoic acid, 2-methyl-, 1,2-ethanediyl ester, polymer with diethenylbenzene, ethenylbenzene and ethenylethylbenzene, chloromethylated, reaction products with trimethylamine is a quaternary ammonium functionalized, strongly basic anion exchange resin. This material is critical for purification and separation processes where high capacity and chemical stability are required. It is primarily utilized in water treatment, pharmaceutical manufacturing, and chemical synthesis for the removal of anions and other impurities.

Application

• Industrial Water Demineralization: Key component in mixed-bed or separate-bed deionization systems to produce high-purity water for power generation, electronics, and boiler feed.
• Pharmaceutical Purification: Used in the purification of active pharmaceutical ingredients (APIs), antibiotics, and other fine chemicals via ion exchange chromatography.
• Catalyst & Reagent: Serves as a solid-phase catalyst or reagent in organic synthesis reactions, facilitating easy separation from the product stream.
• Sugar & Sweetener Processing: Employed in decolorization and deashing steps during the refining of sugar, corn syrup, and other sweeteners.
• Metal Recovery & Hydrometallurgy: Effective for the selective recovery and concentration of precious metals or the removal of contaminant anions from process streams.
• Ultrapure Water (UPW) Production: Essential in the final polishing stages to achieve the stringent ionic purity standards required for semiconductor and microelectronics fabrication.
• Condensate Polishing: Used in power plants to remove ionic contaminants from steam condensate, protecting turbines and boilers from corrosion and scaling.

Quality Control

Our anion exchange resins are manufactured under a strict quality management system. Each batch is tested to ensure consistent performance characteristics such as total exchange capacity, moisture holding capacity, particle size distribution, and ionic form. Certificates of Analysis (COA) detailing these specifications are available upon request. Our production adheres to relevant ISO standards, and materials can be supplied to meet specific pharmacopeial or industrial 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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide, which can affect performance. Keep away from strong oxidizing agents.
