Book Description
The separation of catalysts from solvent and reaction products remains one of the major disadvantages of homogeneous catalytic reactions. In this book we explore a system where a catalyst is dissolved in a thin film of an ionic liquid and this is supported within the pores of a microporous silica. This supported ionic liquid phase catalyst is then placed in a tubular flow reactor, similar to that used for heterogeneous reactions. The raw materials are injected into the rig, passed through the reactor and the products collected at the other end of the rig. Supercritical CO2 is used to transport the raw materials and products along the catalyst bed, allowing a continuous flow mode with low leaching of catalyst and ionic liquid. This system was applied to metathesis, carbonylation and hydrogenation reactions. Furthermore the synthesis of mesoporous silica materials and Rh/Pd hybrid catalysts are also discussed.

Book Description
Although ionic liquids have only been studied in depth during the last decades, the field is now maturing to such a degree that the focus is on larger scale applications for use in real processes such as catalysis. Current information is scattered across the literature and Catalysis in Ionic Liquids provides a critical analysis of the research published to date on ionic solvents in all areas of the catalytic science. The book covers both catalyst synthesis using ionic liquids as solvents and green syntheses using both ionic liquids as well as mixtures of ionic liquids and carbon dioxide (as a subcritical and supercritical liquid), including enzymatic, homogeneous, and heterogeneous catalysis, electrocatalysis and organocatalysis. As well as the catalysis community, the book will also be of interest to postgraduates, postdoctoral workers and researchers in academia and industry working in organic synthesis, new materials synthesis, renewable sources of energy and electrochemistry. Written by leading experts in the field, this is the reference source to find about catalysis in ionic liquids.

Book Description
Multiphase catalysis is a key technology for the competitive and sustainable production of fine chemicals in coming decades. A joint academic and industry consortium has developed tools for considering complex chemical and process-based requirements when setting up a catalytic system. This book shows how the resulting competence covers such supercritical fluid (SCF) technology in catalysis, ionic liquids (Il), ligand design for SFCs and Ils, thermomorphic solvent systems, reactor design and more.

Book Description
Critical overviews from the front line of ionic liquids research Ionic Liquids Completely UnCOILed: Critical Expert Overviews concludes the discussion of new processes and developments in ionic liquid technology introduced in the previously published volumes, Ionic Liquids UnCOILed and Ionic Liquids Further UnCOILed. The goal of this volume is to provide expert overviews that range from applied to theoretical, synthetic to structural, and analytical to toxicological. The value of book lies in the authors’ expertise, and their willingness to share it with the reader. Written by an international group of chemists, the book presents eleven overviews of specific areas of ionic liquid chemistry including: What is an Ionic Liquid? Molecular modelling Crystallography Chemical engineering of ionic liquid processes Toxicology and Biodegradation Organic reaction mechanisms Edited by Professor Ken Seddon and Dr Natalia Plechkova, world leaders in the field of ionic liquids, this book is a must read for R&D chemists, educators, and students, and for commercial developers of environmentally sustainable processes. It offers insight and appreciation for the direction in which the field is going, while also highlighting the best published works available, making it equally valuable to new and experienced chemists alike.
