Available in PDF, EPUB and Kindle. Book excerpt: High pressure chemistry is usually understood to mean the study of reactions in solutions under pressure. Pressure in this connection is commonly agreed to mean at least a kilobar (or roughly a thousand times atmospheric pressure) and, at most, twenty kilobars (since few solutions have not yet solidified at that pressure). The chapters in this book describe how such pressures shift equilibria and how they affect rates. While it is obvious that the changes are in the direction that represents smaller volume, it is less obvious what factors in molecular structure will promote smaller structure. The purpose of this book is to acquaint potential users of high pressure with these factors. The shifts in solution equilibria and rates that pressure can bring about are far larger than most chemists realise. The reason for this unfamiliarity is that many have unwittingly retained the assumption often made in elementary chemistry courses covering gas phase problems that rate and equilibrium constants are functions of temperature but not of pressure, and that only concentrations matter.

The expert editors, Rudi van Eldik and Frank-Gerrit Klärner, provide a comprehensive overview of this fascinating field, ranging from the influence of high pressure on organic and inorganic reactions, via concrete applications in synthesis for metal catalytic and stereoselective processes right up to the use of supercritical liquids. Written by renowned experts, this volume contains a wealth of vital and practical information, for both newcomers to the field as well as experienced high-pressure chemists. Whether in academia or industry, this book belongs on the shelf of every chemist concerned with high-pressure chemistry either now or in the future.

Download or read book High Pressure Chemistry and Biochemistry written by R. van Eldik and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was the objective of the ASI on "Advances in High Pressure Studies of Chemical and Biochemical Systems" to present the current status of such studies and to emphasize the advances achieved during the nine years since the previous ASI on "High Pressure Chemistry". These advances are partly due to the improved instrumentation enabling static and dynamic measurements at pressures several orders of magnitude higher than before, and partly due to the more general availability of high pressure equipment. This has led to a remarkable development in various areas of physics and chemistry, and especially in biochemistry. Throughout the presentation of this Advanced Study Institute the emphasis fell on the teaching character of such a summer school, and the contributions in this volume are of such a nature. Following a general introduction to modern high pressure research, a series of chapters on theoretical and experimental studies of gases, fluids and solids at high temperatures and pressures are presented with special emphasis on the physical aspects involved. Instrumentation used in such studies, viz. shock compression, NMR spectroscopy, laser scattering, x-ray and neutron scattering, and vibrational spectroscopy are treated in detail. The subsequent chapters are devoted to the application of high pressure techniques in the broad areas of organic, inorganic and biochemistry_ The formal lectures were supplemented by 29 contributed papers, for which a list of titles is included.

Download or read book High Pressure Chemical Synthesis written by Janusz Jurczak and published by Elsevier Publishing Company. This book was released on 1989 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: The high pressure method of chemical synthesis is one of the most developed, unconventional tools for preparation of either new or known compounds and as a result there are a large number of interesting reviews in this field of chemistry. Developments in high-pressure inorganic and organic chemistry have been especially numerous and have been the subject of two earlier books Organic High Pressure Chemistry (W. le Noble, Elsevier, 1988) and Inorganic High Pressure Chemistry (R. van Eldik, Elsevier, 1986). This book, intended as a companion volume, highlights the specific problems of chemical synthesis. It has been written to increase the awareness of practising chemists of techniques which could prove advantageous, and to provide a useful summary of information to those engaged in high-pressure research.

Available in PDF, EPUB and Kindle. Book excerpt: Organic materials, containing only H, C, N, and O, are observed in proto-planetary discs, comets and meteorites, which provide the keys to understanding the early Earth. Direct study of two molecules common in these environments, formic acid (HCOOH) and cyanuric acid (H3C3N3O 3), has shown that these molecules survive to higher pressures and temperatures than expected and transform to more complex molecules, implying that high-pressure environments associated with young planets could be a key source of prebiotic molecules in the early Earth. Complementary models of generic planetary interiors have been undertaken, in order to better understand environments outside the Earth which could harbor prebiotic chemistry.
Download or read book High Pressure Chemistry Biochemistry and Materials Science written by R. Winter and published by Springer. This book was released on 2012-10-29 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph, which is the outcome of the ASI on High Pressure Chemistry, Biochemistry, and Materials Science, illustrates new developments in the field of high pressure science. In fact, for chemists, biochemists, and materials scientists, pressure as an experimental variable represents a tool which provides unique information about systems of materials studied. It is interesting to note how the growth of the high pressure field is also reflected in the content of the recent ASI's dealing with this field. The ASI High Pressure Chemistry held in 1977 was followed by the ASI High Pressure Chemistry and Biochemistry held in 1986, and the coverage of the present ASI also includes applications to materials science. In view of the teaching character of the ASI, it is natural that main contributions to this volume present overviews of the different subfields or applications of high pressure research. In contrast, contributed papers offer more specialized aspects of various high pressure studies. The various contributions to this volume make clear the impressive range of fundamental and applied problems that can be studied by high pressure techniques, and also point towards a major growth of high pressure science and technology in the near future. This ASI focused mainly on advances achieved in the six years since the previous ASI devoted to the high pressure field. The organization of this volume is as follows.

Download or read book Activation Methods written by Jean-Philippe Goddard and published by John Wiley & Sons. This book was released on 2020-02-26 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Activation Methods examines recent improvements in the utilization of ultrasonic waves and pressurized gases to generate reactions. A straightforward method to use, sonochemistry allows chemical reactions to be carried out under ultrasound without the need for external heat, reagents or catalysts – leading to high yields and the production of a minimum amount of waste. This book presents an overview of the main applications of sonochemistry in green organic chemistry, with an emphasis on texts published within the last few years. High-pressure chemical reactions offer innovative solutions to problems relating to synthesis. They allow access to new products and a further understanding of reaction mechanisms. This book presents the characteristics of hyperbaric activation, which allow the integration of an arsenal of tools for green chemistry, such as the lowering of energy costs and of by-products, as well as the possibility of using substrates that are sterically congested and generally inert.
