Aromatic Fluorination (Hardcover): James H. Clark Aromatic Fluorination (Hardcover)
James H. Clark
R2,848 Discovery Miles 28 480 Ships in 12 - 17 working days

Academia and industry join forces in Aromatic Fluorination, as an expert from each domain contributes to this new text on fluorination of carbocyclic and heterocyclic rings. The book begins with a discussion of fluorine's unique combination of properties, including size, electronic effects, and hydrophobicity, as well as the historical development of its product applications. It explains methods for introducing fluorine into an aromatic ring, focusing on nucleophilic fluorine transfer reactions. The role of catalysts, solvents, and other variables are examined, and the scope and limitations of the methods are discussed. Of particular interest to those working in non-specialist laboratories, Aromatic Fluorination includes detailed descriptions of the new electrophilic routes to fluoroaromatics, in addition to traditional routes and alternative methods involving radical chemistry. Because one of the most important fluorine-containing substituent is CF3, the book explains routes to benzotrifluorides (ArCF3), including traditional industrial methods and modern alternatives employing C-1 halofluorocarbons and other fluoroaliphatics. An alternative to CF3 is CF3S, and several methods of synthesizing aromatic CF3S-containing molecules are described. Since the successful development and diverse applications of aromatic fluorine compounds have led to the search for new compounds and novel substituents, the incorporation of other substituents is also explored. Aromatic Fluorination concludes with discussion of the factors responsible for the successful development of pharmaceutical, agrochemical and liquid crystal applications and the potential for applications in high-performance polymers and other areas. This section also describes in detail important industrial aromatic fluorination processes and the relative merits of different process technologies and their costs.

Gene Regulation by Steroid Hormones III (Paperback, Softcover reprint of the original 1st ed. 1987): Arun K. Roy, James H. Clark Gene Regulation by Steroid Hormones III (Paperback, Softcover reprint of the original 1st ed. 1987)

The field of steroid hormone action has continued to expand into the realm of molecular biology at a pace even faster than most of us ever imagined. techniques of molecular biology have made it possible to clone The hormone-regulated genes and to examine steroid-receptor interactions with these genes. Nucleotide sequences of these genes, which show preferential binding of steroid receptors, have been identified. These results are complemented by the identification of chromatin acceptor proteins, which also show preferential binding for steroid-receptor complexes. Thus, one can envision the day when cloned genes, purified acceptor proteins, and receptor-steroid complexes will be recombined in vitro to form a functional unit. Cellular localization of steroid receptors has undergone recent revision, and it now appears that receptors are localized primarily in the nuclear compartment. These findings, although controversial, will lead to a reassessment of many of the previous concepts of steroid-receptor interactions and regulation. The way in which these observations at the of physiology, molecular and cellular levels fit into the overall scheme development, and evolution are continuing to progress, and the future promises some very exciting syntheses of understanding at all levels of biological organization. The third Meadow Brook Conference on hormones was held in order to bring together investigators who will undoubtedly contribute heavily to this future synthesis and to permit a free exchange of ideas and concepts as they relate to the current state-of-the-art in molecular endocrinology.

The first Meadowbrook Symposium was held in 1978 and during the intervening ten years our knowledge concerning how steroid hormones function at the level of gene expression has advanced by leaps and bounds. In this volume, which sum marizes our fourth meeting, these advances are very evident. What seemed like science fiction ten years ago has become commonplace science. Who would have imagined that we could synthesize a nucleotide sequence that binds a specific steroid receptor and acts as a controlling element for gene expression? No one; but as is evident from the results reported in several chapters, this technique is yielding a wealth of information. Using these and other techniques it has become apparent that gene transcription is controlled by interactions between transacting factors and DNA recognition sequences (response elements). These transacting factors appear to be members of a large gene family that includes steroid hormone receptors, transcription factors, protooncogenes and homeobox proteins. Thus a great deal has been learned, but as usual, questions remain. Many of these questions are posed by the findings and observations found in several chapters in this volume. Non hormone binding forms of steroid receptors and their relevance to receptor down regulation, recycling and biological response remain a mystery. The quantitative relationship between receptor binding and biological response still presents agonizing problems. These and many other intriguing questions are discussed in this volume and set the stage for what should be a most rewarding time in endocrinology. Winter 1989 ARUN K."

Green chemistry has progressed from being a driver for change in the chemical and allied industries to being a critical part of chemical education at all levels. The future chemist must be able to practice their trade in the light of increasing concerns about waste and resources, the safety of chemicals in consumer products, and increasingly restrictive legislation. While there are green chemistry educational resources available including lectures and experiments as well as numerous books on green chemistry and major green chemical technologies, there is no "green equivalent" of a standard organic chemistry textbook Systematically covering a variety of well-known reactions that commonly feature in standard organic textbooks this book supplements and supports the standard organic chemistry texts. It highlights the main sustainability issues of classical and contemporary organic transformations and critically evaluates them within a metric of established Green Chemistry Principles noting where additional efforts are needed to improve their environmental footprint. Written by a team of expert authors with a multinational advisory board, this book is a fantastic resource for advanced undergraduate and postgraduate students worldwide.

Globally we are being confronted by the depletion of many natural resources as a result of unsustainable use and increasing global population. Although the debate on the bioeconomy has gained momentum in recent decades, the interest in certifications and standards for biobased products is still weak. This book aims to fill this gap by promoting a holistic approach, which covers environmental, social and economic sustainability aspects and pushes forward the development of a circular, biobased economy. This book promotes the development of sustainability schemes (including standards, labels and certifications) for the assessment of biobased products, which are fundamental to the establishment of a cutting-edge sustainable bioeconomy. Chemical-related, globally relevant case studies are used throughout the book. The content covers a range of issues from upstream and downstream environmental, techno-economic and social assessment, to crosscutting issues such as indirect land use change (iLUC) and end-of-life options. The chapters included in this book will provide a comprehensive review of recent works on life cycle assessment (LCA), life cycle costing (LCC) and social life cycle assessment (s-LCA) methodologies. An important resource for researchers, industrial professionals and policy makers involved in the bioeconomy.

Clean Energy presents a broad survey of the energy problems facing society over the coming decades and the prospects for their solution. The book emphasizes the importance of developing a strategy for the world's future energy supply. The strategy must take into account: the finite supplies of natural gas and petroleum; the increased consumption of fuel by developing economies; the concern over greenhouse gas emissions; the pollution caused by burning coal (especially coal with a high sulphur content); the difficulties and costs of extracting unconventional fossil fuels; and the technical, sociological and cost barriers that restrict the use of renewable forms of energy. Clean Energy sets the various renewable energies (wind, waves, solar etc) in the context of present and projected world production of energy and its use in the time-frame until 2020 and looks speculatively beyond that. It looks at the possibilities for reducing pollution from fossil fuels and tackles the serious problem of how to store energy, in order to smooth out fluctuations in supply and demand. Clean Energy is well illustrated with diagrams and photographs. It is accessible to anyone who has studied science to A-level and will appeal to anyone with a serious interest in environmental matters, and the interaction between energy usage and the environment.

R2,487 Discovery Miles 24 870 Ships in 10 - 15 working days

Sulfur compounds contaminate many industrially important feedstocks and, on release to the atmosphere as sulfur oxides, can cause widespread damage to the ecosystem. The main objectives of The Sulfur Problem: Cleaning Up Industrial Feedstocks are to demonstrate the importance of eliminating sulfur contaminants from the environment and the measures necessary to effect this. Using a systematic and pedagogical approach, the reader is first presented with the problem. Current technology for solving it is then outlined together with appropriate theory on the synthesis, structure and sorption behaviour of the materials used. Relevant characterisation techniques are described with reference to typical sorbents, to demonstrate how the sorption behaviour of the materials correlates with their properties. The book is unique in blending together aspects of environmental chemistry, materials/solid state chemistry, surface chemistry, catalysis and separation processes to address the problem of sulfur contaminants in a wide range of feedstocks.

Waste minimisation has a number of aims which include enhancing the intrinsic selectivity of any given process, providing a means of recovering reagents in a form which allows easy regeneration and the replacement of stoichiometric processes with catalytic ones. Solids, as catalysts or as supports for other reagents, offer potential for benefit in all these areas. This monograph provides an overview of the properties of the more useful solid catalysts and supported reagents, and highlights their most valuable applications in the preparation of organic chemicals in liquid phase reactions. Clean Synthesis Using Porous Inorganic Solid Catalysts and Supported Reagents is concerned with the use of solid catalysts in the clean synthesis of organic chemicals. The emphasis is on chemical processes of importance to the manufacture/preparation of fine and speciality chemicals, chemical intermediates and pharmaceutical intermediates, especially where catalysis is not currently used or where current catalysts are homogeneous, leading to difficult separation procedures and unacceptable levels of waste. This book focuses on solid catalysts based on inorganic supports and covers the emerging area of chemically modified mesoporous solid catalysts.

Simple, but beautifully versatile. Perhaps not a description many would choose for hydrogen peroxide, but an accurate one none the less, and this unique book explains the reasons behind the description. Beginning with an historical overview, and guidelines for the safe handling of peroxygens, Applications of Hydrogen Peroxide and Derivatives goes on to cover key activation mechanisms, organic functional group oxidations and the use of hydrogen peroxide with heterogeneous catalysts. The clean-up of environmental pollutants; chemical purification; and extraction of metals from their ores are also discussed in detail, using actual examples from industry. The versatility of this reagent may well prove to be a key to integrated pollution control in the future. This book should therefore be read by academics and industrialists at all levels, to encourage wider applications of the use of hydrogen peroxide in laboratories.

The use of plastic materials has seen a massive increase in recent years, and generation of plastic wastes has grown proportionately. Recycling of these wastes to reduce landfill disposal is problematic due to the wide variation in properties and chemical composition among the different types of plastics. Feedstock recycling is one of the alternatives available for consideration, and Feedstock Recycling of Plastic Wastes looks at the conversion of plastic wastes into valuable chemicals useful as fuels or raw materials. Looking at both scientific and technical aspects of the recycling developments, this book describes the alternatives available. Areas include chemical depolymerization, thermal processes, oxidation and hydrogenation. Besides conventional treatments, new technological approaches for the degradation of plastics, such as conversion under supercritical conditions and coprocessing with coal are discussed.

This book is essential reading for those involved in plastic recycling, whether from an academic or industrial perspective. Consultants and government agencies will also find it immensely useful.

Polymer science faces the challenge of meeting growing market demand for polymers whilst achieving sustainability through environmentally friendly processes. Microwave heating has emerged as a greener technique that accelerates a variety of chemical reactions, including polymerization. Microwave-assisted reactions can be cleaner and more rapid and economic analyses suggest that the cost of curing polymers may be reduced by switching over to the use of microwaves. This book provides comprehensive coverage of microwave-assisted polymerization. The first chapter introduces readers to the theory behind the accelerating effects of microwaves on chemical reactions and covers the types of commercial microwave reactors being used for synthesis and processing of polymers that are available on the market. Subsequent chapters are organised by type of reaction, including radical homo and co-polymerizations, step growth polymerization and peptide synthesis. Importantly, analysis of processes and product properties in comparison with conventional methods is also detailed. This book will be a valuable resource for green chemists and polymer scientists and engineers who want to develop sustainable processes.
