Description

Polymer-Bound Chlorotris(Triphenylphosphine)Rhodium(I) On Styrene-Divinylbenzene Copolymer (20% Cross-Linked) is a high-performance, heterogeneous catalyst where the active rhodium(I) complex is immobilized on a robust polymeric support. This product matters because it combines the high catalytic activity of Wilkinson's catalyst derivative with the significant advantages of easy separation and reusability, which are critical for cost-effective and sustainable chemical processes. It is primarily needed by R&D chemists and process engineers in the fine chemical and pharmaceutical industries for hydrogenation and hydroformylation reactions, enabling streamlined workflows and simplified product purification.

Application

• Selective Hydrogenation Catalysis: For the reduction of alkenes, alkynes, and other unsaturated compounds in fine chemical and pharmaceutical intermediate synthesis.
• Hydroformylation Reactions: Used in the conversion of alkenes to aldehydes, a key step in oxo processes for producing plasticizers and detergents.
• Heterogeneous Process Development: Ideal for flow chemistry and continuous manufacturing setups where solid-supported catalysts are essential.
• Asymmetric Synthesis Support: Serves as a foundational material for developing chiral heterogeneous catalysts for enantioselective transformations.
• Academic and Industrial R&D: A valuable tool for research into new catalytic cycles and the study of supported metal complex behavior.
• Recovery and Recycling Studies: Used in processes where catalyst recovery and metal containment are priorities to minimize rhodium loss and environmental impact.

Quality Control

Every batch of our polymer-supported rhodium catalyst is produced and tested under stringent quality protocols to ensure consistent catalytic activity and reliable performance. Quality assurance includes analysis of rhodium loading, phosphine content, and bead integrity. A comprehensive Certificate of Analysis (COA) detailing lot-specific specifications is provided with each shipment to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity, the container should only be opened in an inert environment to prevent oxidation and moisture uptake.
