Produktbeschreibung
Recoverable and Recyclable Catalysts There is continued pressure on chemical and pharmaceuticalindustries to reduce chemical waste and improve the selectivity andefficiency of synthetic processes. The need to implement greenchemistry principles is a driving force towards the development ofrecoverable and recyclable catalysts. The design and synthesis of recoverable catalysts is a highlychallenging interdisciplinary field combining chemistry, materialsscience engineering with economic and environmental objectives.Drawing on international research and highlighting recentdevelopments, this book serves as a practical guide for bothexperts and newcomers to the field. Topics covered include: * An introduction to the principles of catalyst recovery andrecycling * Catalysts on insoluble and soluble support materials * Thermomorphic catalysts, self-supported catalysts andperfluorous catalytic systems * The development of reusable organic catalysts * Continuous flow and membrane reactors Each chapter combines principles with practical information onthe synthesis of catalysts and strategies for catalyst recovery.The book concludes with a comparison of different catalyticsystems, using case studies to illustrate the key features of eachapproach. Recoverable and Recyclable Catalysts is a valuablereference source for academic researchers and professionals from arange of pharmaceutical and chemical industries, particularly thoseworking in catalysis, organic synthesis and sustainablechemistry.
