Download or read book Oxygenates by Homologation or CO Hydrogenation with Metal Complexes written by A. Braca and published by Springer Science & Business Media. This book was released on 1993-12-31 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Born and initially developed in various industrial laboratories, mainly in U.S.A. and Gennany, homogeneous phase catalytic carbon monoxide hydrogenation and alcohols and their derivatives carbonylation and homologation, have generally been considered and reviewed separately in the course of their 40 years history without concern for common aspects in the chemical transfonnations and in catalysis. Thanks to researchers of Japanese companies participating in the National C 1 Chemistry Project (1980-1987) the scientific and technical approaches in this field have been unified and applied in parallel, in the light of some common aspects of the chemical reactions and mechanisms. Now, at a moment when research seems becahned, a general presentation and discussion of the most recent topics might be an useful basis for further development of this chemistry. To delimit and simplify the discussion of the chemical aspects and the nature of the catalysts involved, the present review is limited to reactions employing homogeneous metal complexes for the direct conversion of syngas to oxygenates and to the hydrocarbonylation of these last to homologous derivatives. Since the previous practically contemporary reviews by Dombek [in Adv. Organomet. Chern. (1983)] on CO hydrogenation and by the present authors [in Asp.Homog.Catal.(Reidel Pu.l984)] on alcohol homologation fully cover the literature up to 1982, here we mainly refer to work done after 1982, and consider the cited reviews as covering the historical development of research in the 1940- 1980 period.

Download or read book Rhodium Catalyzed Hydroformylation written by Piet W.N.M. van Leeuwen and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last decade there have been numerous advances in the area of rhodium-catalyzed hydroformylation, such as highly selective catalysts of industrial importance, new insights into mechanisms of the reaction, very selective asymmetric catalysts, in situ characterization and application to organic synthesis. The views on hydroformylation which still prevail in the current textbooks have become obsolete in several respects. Therefore, it was felt timely to collect these advances in a book. The book contains a series of chapters discussing several rhodium systems arranged according to ligand type, including asymmetric ligands, a chapter on applications in organic chemistry, a chapter on modern processes and separations, and a chapter on catalyst preparation and laboratory techniques. This book concentrates on highlights, rather than a concise review mentioning all articles in just one line. The book aims at an audience of advanced students, experts in the field, and scientists from related fields. The didactic approach also makes it useful as a guide for an advanced course.

Download or read book The Effects of Potassium on Carbon Monoxide Methanation Over Supported Rhodium Films written by C. H. Dai and published by . This book was released on 1986 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reaction of hydrogen with carbon monoxide over Rh/Al2O3 and Rh/TiO2 catalytic films, some of which contained potassium as an additive, has been investigated. The presence of potassium caused the usual gem dicarbonyl and linear CO species on supported rhodium to dissociate at lower temperature than for catalysts containing no potassium. On the other hand, the bridged carbonyl species was significantly enhanced by the presence of potassium. The Rh/TiO2 films to which potassium was added catalyzed the production of significant amounts of acetone and acetaldehyde as oxigenated products. It is likely that the bridged carbonyl species is the precursor to oxygenated products.

Download or read book Advances in Chemical Conversions for Mitigating Carbon Dioxide written by T. Inui and published by Elsevier. This book was released on 1998-03-12 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global environmental problems, especially global warming caused by the accelerative accumulation of carbon dioxide in the atmosphere, are of great importance for humans. The world's population is now approaching 6 billion, and is still increasing. Developments in communication systems and transportation tools have made the circulation of information, technologies and materials easier, which results in rapid economic growth, particularly in the East and Southeastern Asian countries. Increased affluence leads to an increased consumption of fossil fuels. Inevitably, this leads to an increase in carbon dioxide emission and environmentally hazardous materials which in turn precipitates climatic changes on a global scale. Recent studies showed that the increase in carbon dioxide emission for last year was the highest in the past seven years, and the total amount of carbon dioxide emission from all over the world reached 6.5 billion tons. Furthermore, one cannot overlook the report which appeared recently in Nature, that the floor-area of the iceberg in the South Pole has already decreased by 25% in the past five decades. Over 260 scientists and engineers from 21 countries who had a strong interest and wished to contribute to solve the carbon dioxide problem attended this conference. The papers presented in this volume cover most of the possibilities of the chemical conversion of carbon dioxide.

Download or read book Homogeneous Transition-metal Catalysis written by Christopher Masters and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soluble catalysts are used extensively in many branches of chemistry and are indeed a vital constituent of many natural processes. They find wide application throughout the chemical industry where they assist in the production of several million tonnes of chemicals each year. Since homogeneous systems, especially those incorporating transition metals, often function effectively under milder conditions than their heterogeneous counterparts, they are becoming increasingly important at a time when the chemical industry in particular, and society in general, is seeking ways of conserving energy and of making the best possible use of available resources. My principal objective in- writing this book is to engender sufficient enthusiasm for, and knowledge of, the subject in the reader that he or she will be encouraged to begin, or continue, to make their own contribution to advancing our knowledge of homogeneous catalysis. After attempting to acquaint the reader with some of the ground rules I have tried to describe the present scope, and the future potential, of this fascinating field of chemistry by drawing both on academic and on industrial data sources. This approach stems from a personal conviction that future progress could be considerably hastened by a more meaningful dialogue between chemists working both in industrial and in academic research institutions. Wherever possible, examples of the commercial application of homogeneous catalyst systems have been included and no attempt has been made in any way to disguise the many unresolved questions and exciting challenges which still pervade this rapidly developing area.

Download or read book Catalytic Hydrogenation of Carbon Monoxide written by and published by . This book was released on 1992 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is focused on developing strategies to accomplish the reduction and hydrogenation of carbon monoxide to produce organic oxygenates at mild conditions. Our approaches to this issue are based on the recognition that rhodium macrocycles have unusually favorable thermodynamic values for producing a series of intermediate implicated in the catalytic hydrogenation of CO. Observations of metalloformyl complexes produced by reactions of H2 and CO, and reductive coupling of CO to form metallo?-diketone species have suggested a multiplicity of routes to organic oxygenates that utilize these species as intermediates. Thermodynamic and kinetic-mechanistic studies are used in constructing energy profiles for a variety of potential pathways, and these schemes are used in guiding the design of new metallospecies to improve the thermodynamic and kinetic factors for individual steps in the overall process. Variation of the electronic and steric effects associated with the ligand arrays along with the influences of the reaction medium provide the chemical tools for tuning these factors. Emerging knowledge of the factors that contribute to M-H, M-C and M-O bond enthalpies is directing the search for ligand arrays that will expand the range of metal species that have favorable thermodynamic parameters to produce the primary intermediates for CO hydrogenation. Studies of rhodium complexes are being extended to non-macrocyclic ligand complexes that emulate the favorable thermodynamic features associated with rhodium macrocycles, but that also manifest improved reaction kinetics. Multifunctional catalyst systems designed to couple the ability of rhodium complexes to produce formyl and diketone intermediates with a second catalyst that hydrogenates these imtermediates are promising approaches to accomplish CO hydrogenation at mild conditions.

Available in PDF, EPUB and Kindle. Book excerpt: The interaction of carbon monoxide (CO) and oxygen on Rhodium (Rh) is very interesting and important due to its applications in catalysis ( e.g., catalytic converters in automobiles). The main purpose of our research is to study the reaction between oxygen atoms and carbon monoxide molecules present on Rhodium terraces, as well as the binding of carbon monoxide molecules to the surface. In particular, we are looking at the mechanism at low temperatures where catalytic converters are not as effective. Our primary objective was to study the effect on the results of varying the rate constants for the different processes (CO oxidation, CO binding to the surface, CO mobility). To this end, we have developed a computer simulation program incorporating the rate constants as variable parameters. The magnitude of the rate constants is related to the relative strengths (probabilities) of the interactions. So, as we identified particular interactions {values of rate constants) that led to enhanced reactivity, we gained a better understanding of how the proposed mechanism relates to the physical processes occurring. This basic understanding of the reaction system may eventually lead to modifications that will improve the function of the catalyst.
