Recoverable and Recyclable Catalysts There is continued pressure on chemical and pharmaceutical industries to reduce chemical waste and improve the selectivity and efficiency of synthetic processes. The need to implement green chemistry principles is a driving force towards the development of recoverable and recyclable catalysts. The design and synthesis of recoverable catalysts is a highly challenging interdisciplinary field combining chemistry, materials science engineering with economic and environmental objectives. Drawing on international research and highlighting recent developments, this book serves as a practical guide for both experts and newcomers to the field. Topics covered include: An introduction to the principles of catalyst recovery and recycling Catalysts on insoluble and soluble support materials Thermomorphic catalysts, self-supported catalysts and perfluorous catalytic systems The development of reusable organic catalysts Continuous flow and membrane reactors Each chapter combines principles with practical information on the synthesis of catalysts and strategies for catalyst recovery. The book concludes with a comparison of different catalytic systems, using case studies to illustrate the key features of each approach. Recoverable and Recyclable Catalysts is a valuable reference source for academic researchers and professionals from a range of pharmaceutical and chemical industries, particularly those working in catalysis, organic synthesis and sustainable chemistry.

This book looks at new ways of tackling the problem of separating reaction products from homogeneous catalytic solutions. The new processes involve low leaching supported catalysts, soluble supports such as polymers and dendrimers and unusual solvents such as water, fluorinated organics, ionic liquids and supercritical fluids. The advantages of the different possibilities are discussed alongside suggestions for further research that will be required for commercialisation. Unlike other books, in addition to the chemistry involved, the book looks at the process design that would be required to bring the new approaches to fruition. Comparisons are given with existing processes that have already been successfully applied and examples are given where these approaches are not suitable. The book includes: - New processes for the separation of products from solutions containing homogeneous catalysts - Catalysts on insoluble or soluble supports – fixed bed catalysts - continuous flow or ultrafiltration - Biphasic systems: water - organic, fluorous - organic, ionic liquid – organic, supercritical fluids (monophasic or biphasic with water, organic or ionic liquid) - Comparisons with current processes involving atmospheric or low temperature distillation - Consideration of Chemistry and Process Design - Advantages and disadvantages of each process exposed - Consideration of what else is need for commercialisation

This book provides an interdisciplinary, integrative overview of environmental problem-solving using mild reaction conditions, green reagents, waste free and energy efficient synthesis in both industry and academic world. Discussions include a broad, integrated perspective on sustainability, integrated risk, multi-scale changes and impacts taking place within ecosystems worldwide. Features: This book serves as a reference book for scientific investigators who need to do greener synthesis of organic compounds, drugs and natural products under mild reaction condition using green reagents, eco-friendly catalysts and benign reaction mediums over traditional synthetic processes which is a key driving force of scientists. Greener synthesis of multiple value-added heterocycles opens up a new horizon towards the organic catalysis and for this purpose, development of natural resources acts as an effective catalyst. Using environmentally friendly reaction medium e.g. ACC, WETSA, WEBSA have been used for the synthesis of some crucial heterocyclic scaffolds such as bisenols and 2-amino-4H-pyrans, tetraketones, pyrans, and biaryls. This book can also be used as a textbook for graduate and post graduate level courses for students. Furthermore, the problems with answers in book will add better understanding for students.

The authors distill the most relevant applications of recyclable homogeneous catalysts rather than list every example found in the field. This provides a framework to the readers, allowing them to ask the most relevant questions about recyclable homogeneous catalysis applications in their area of interest. Recyclable Homogeneous Catalysis uses physical and chemical engineering methods specifically designed for high recoverability. Some of the recovery methods include the use of multi-phasic solvent systems, distillation, and extractions. In addition, by using careful catalyst design, the active metal center can be embedded onto a solid support or polymer to increase recoverability. The catalysts discussed in this primer are used in a range of reactions such as polymerization, CO2 capture, and amination. Graduate students and early career professionals who want to get into the field of recyclable catalysts will benefit from reading this work.
