Description

Amberlyst(R) 15 is a macroreticular, strongly acidic cation exchange resin supplied in the dry, hydrogen form. This robust solid acid catalyst is valued for its high thermal stability, excellent chemical resistance, and ease of separation from reaction mixtures, making it a superior alternative to traditional liquid mineral acids. It is essential for chemical engineers and process chemists in industries requiring efficient, recoverable, and environmentally friendlier acid catalysis for a wide range of organic transformations.

Application

• Esterification and Transesterification Reactions: Key catalyst for producing biodiesel, plasticizers, and flavor/fragrance esters.
• Alkylation and Acylation: Used in Friedel-Crafts reactions for synthesizing fine chemicals and pharmaceutical intermediates.
• Hydration and Dehydration Reactions: Effective for converting olefins to alcohols or ethers, and for removing water to form alkenes or cyclic compounds.
• Protection/Deprotection Chemistry: Facilitates the formation and cleavage of acid-labile protecting groups in complex multi-step syntheses.
• Chemical Purification: Acts as an acid scavenger or catalyst support in purification processes and continuous flow systems.
• Resin Pretreatment & Conditioning: Serves as a precursor or conditioning agent in water treatment and other ion exchange applications.

Quality Control

Our Amberlyst(R) 15 is manufactured under a strict quality management system. Every batch is tested to ensure consistent catalytic performance, acid capacity, and physical integrity. Key parameters such as exchange capacity, moisture content, particle size distribution, and thermal stability are verified. A Certificate of Analysis (COA) detailing these specifications is provided with each shipment to guarantee it meets the high standards required for industrial catalysis and chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept sealed to prevent absorption of atmospheric moisture, which can affect its catalytic activity and handling properties. Keep away from strong bases and oxidizing agents.
