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.

Download or read book The Role of High pressure Organic Chemistry in Planetary Evolution written by Wren Bowlan Montgomery and published by . This book was released on 2007 with total page 138 pages. 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.

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: High-Pressure Chemistry and Physics of Polymers is devoted to covering all areas of high-pressure polymer materials science. Topics addressed include the synthesis of polymers, changes in reactivity, structural transformations, molecular dynamics, relaxation processes, deformational properties, chemical modification, and the effect of shock waves and shear stresses. The authors' contributions reflect over 60 years of Soviet study in the field of physico-chemistry conducted at the major former Soviet Institutes of Chemical Physics, Organic Chemistry, Polymer Chemistry, and Physical Chemistry. Fundamental topics such as compressibility of polymers, polymerization under pressure, viscoelastic/deformational properties, and polymer modification are discussed with an eye toward materials development for improving physical models and methods of calculating the changing parameters of materials under pressure. The book is a valuable reference to data on mechanisms of physical and chemical processes, in addition to new experimental data for improving physical models and methods of calculating changes in material characteristics under compression loads. High-Pressure Chemistry and Physics of Polymers will be an important reference for graduate students and practicing professionals in polymer chemistry and polymeric materials.

Download or read book High Pressure Phenomena written by R.J. Hemley and published by IOS Press. This book was released on 2002-11-29 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many respects, the science of materials has only fully utilized two of its three fundamental tools - the variables of temperature and chemical composition. Pressure, the third fundamental variable altering materials, is in many ways the most remarkable, as it spans some 60 orders of magnitude in the universe. High-pressure science has experienced tremendous growth, particularly in the last few years. With recent developments in static and dynamic compression techniques, extreme pressure and temperature conditions can now be produced and carefully controlled over a wide range. Moreover, a new generation of analytical probes, many based on third-generation synchrotron radiation sources, have been developed and can now be applied for accurate determination of the structural, dynamical, and electronic properties of matter under extreme conditions. Finally, developments in computational techniques and advances in fundamental theory tested against bountiful new experimental results are both deepening our understanding of materials as a whole and guiding subsequent experimental work with new predictions. It was for this reason that this course on high-pressure science was held at the International School of Physics "Enrico Fermi" School in July 2001. Though presented in a physics forum, the title “High-Pressure Phenomena” was chosen to reflect the broad scope of the field and the diversity of recent findings. Indeed, the field spans fundamental physics and chemistry, materials science and technology, the geosciences, planetary science and astrophysics, as well as biology. The highly interdisciplinary character of the field was central to the organization of the school, though the sheer breadth of the field meant that many topics could be treated in only a cursory fashion while others were examined more in depth. The aim of the school was to present the state-of-the-art in techniques used in modern high-pressure research, highlighting those topics where applications of these techniques are currently having a major impact.

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.
