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. - Springer, 2006.
Despite the fact that more than 900f production processes in industry are catalyzed, most chemists and engineers are restricted to trial and error when searching for the proper catalyst. This book is the first emphasizing industrial aspects of catalysis and also particularly well suited to studying on one's own. It is dedicated to both, homogeneous and heterogeneous catalysis and in this second, edition biocatalysis, electrocatalysis, photocatalysis and asymmetric catalysis are also included; topics like zeolites, metals and olefin catalysis are now discussed in more detail. The book aids practically oriented readers in becoming familiar with the processes of catalyst development and testing and therefore deals with aspects of test planning, optimization and reactor modeling and simulation with the easy-to-learn PC program POLYMATH. Well over 100 exercises help to test and consolidate the gained knowledge. - Wiley-VCH; 2006.
An integrated approach to the molecular theory of reaction mechanism in heterogeneous catalysis, largely based on the knowledge among the growing theoretical catalysis community over the past half century, and covering all major catalytic systems. The authors develop a general conceptual framework, including in-depth comparisons with enzyme catalysis, biomineralisation, organometallic and coordination chemistry. A chapter dedicated to molecular electrocatalysis addresses the molecular description of reactions at the liquid-solid interphase, while studies range from a quantum-chemical treatment of individual molecular states to dynamic Monte-Carlo simulations, including the full flexibility of the many-particle systems. Complexity in catalysis is explained in chapters on self-organization and self-assembly of catalysts, and other sections are devoted to evolutionary, combinatorial techniques as well as artificial chemistry. - Wiley-VCH; 2006.
