| chiral or achiral practice: Comprehensive Chirality , 2012-12-31 Although many books exist on the subject of chiral chemistry, they only briefly cover chiral synthesis and analysis as a minor part of a larger work, to date there are none that pull together the background information and latest advances in one comprehensive reference work. Comprehensive Chirality provides a complete overview of the field, and includes chiral research relevant to synthesis, analytic chemistry, catalysis, and pharmaceuticals. The individual chapters in each of the 9 volumes provide an in depth review and collection of references on definition, technology, applications and a guide/links to the related literature. Whether in an Academic or Corporate setting, these chapters will form an invaluable resource for advanced students/researchers new to an area and those who need further background or answers to a particular problem, particularly in the development of drugs. Chirality research today is a central theme in chemistry and biology and is growing in importance across a number of disciplinary boundaries. These studies do not always share a unique identifying factor or subject themselves to clear and concise definitions. This work unites the different areas of research and allows anyone working or researching in chiral chemistry to navigate through the most essential concepts with ease, saving them time and vastly improving their understanding. The field of chirality counts several journals that are directly and indirectly concerned with the field. There is no reference work that encompasses the entire field and unites the different areas of research through deep foundational reviews. Comprehensive Chirality fills this vacuum, and can be considered the definitive work. It will help users apply context to the diverse journal literature offering and aid them in identifying areas for further research and/or for solving problems. Chief Editors, Hisashi Yamamoto (University of Chicago) and Erick Carreira (ETH Zürich) have assembled an impressive, world-class team of Volume Editors and Contributing Authors. Each chapter has been painstakingly reviewed and checked for consistent high quality. The result is an authoritative overview which ties the literature together and provides the user with a reliable background information and citation resource. |

| chiral or achiral practice: Enantiomer Separation Fumio Toda, 2007-11-04 In spite of important advances in asymmetric synthesis, chiral compounds cannot all be obtained in a pure state by asymmetric synthesis. As a result, enantiomer separation remains an important technique for obtaining optically active materials. Although asymmetric synthesis is a once-only procedure, an enantiomer separation process can be repeated until the optically pure sample is obtained. This book discusses several new enantiomer separation methods using modern techniques developed by experts in the field. These methods consist mainly of the following three types: 1) Enantiomer separation by inclusion complexation with a chiral host compound 2) Enantiomer separation using biological methods 3) Enantiomer separation by HPLC chromatography using a column containing a chiral stationary phase. Separation of a racemic compound has been called “optical resolution” or simply “resolution”. Nowadays, the descriptions “enantiomer resolution” or “enantiomer separation” are also commonly used. Accordingly, “Enantiomer Separation” is used in the title of this book. The editor and all chapter contributors hope that this book is helpful for scientists and engineers working in this field. |

| chiral or achiral practice: Organic Chemistry Principles and Industrial Practice Mark M. Green, Harold A. Wittcoff, 2003-09-19 Nylon, Plexiglas, Dynamit: Viele industrielle Erzeugnisse verdanken wir den Prinzipien der organischen Chemie. Prinzipien, die Chemiestudenten vielfach als trockenen Lehrstoff ohne jeden praktischen Bezug büffeln müssen. Dass es auch anders geht, zeigen Green und Wittcoff. In zehn knappen Kapiteln verknüpfen sie die Theorie mit industriellen Prozessen - ein Gewinn nicht nur für Studenten, sondern auch für Lehrende. Da die meisten Chemiestudenten in ihrem späteren Berufsleben mit Problemen der organischen Chemie konfrontiert sein werden, sollte diese breite Zielgruppe nach Ansicht der beiden Autoren schon vom Beginn ihrer akademischen Ausbildung an über industrielle Produkte und Prozesse informiert werden. Organic Chemistry Principles and Industrial Practice beschreibt die Geschichte der industriellen Chemie, liefert wertvolle, sonst kaum zugängliche Informationen und bietet nicht zuletzt auch zahlreiche Anekdoten aus dem reichen Erfahrungsschatz der Autoren. Beide sind langjährige Dozenten. Sie liefern eine leicht zu lesende, klar strukturierte Einführung, die tieferes Verständnis der Grundlagen der organischen Chemie und ihrer Anwendungen ermöglicht. Das Werk eignet sich hervorragend als Ergänzung zu den Lehrbüchern, kann aber auch von Studenten höherer Semester, Laborassistenten, Chemieingenieuren und Chemikern in der Industrie genutzt werden. Die Autoren zeigen unter anderem, wie aus Petroleum nützliche Dinge werden, gehen auf die zentrale Rolle der elektrophilen aromatischen Substitution ein, erzählen die Nylon-Story, beschäftigen sich mit Polyethylen, Polypropylen und den Grundlagen der Stereochemie und vergessen auch natürliches Gummi und andere Elastomere nicht. |

| chiral or achiral practice: Physical Principles of Chirality in NMR Piotr Garbacz, 2024-09-20 How can we study one of the most elusive molecular properties, chirality, using nuclear interactions with the magnetic field that are apparently insensitive to handedness? This book answers this question from the physicochemical point of view by providing a clear, coherent, and comprehensive review of methods used in NMR studies of chirality. Presented arguments based on fundamental physical and chemical laws and in-depth descriptions of new methods utilizing purely physical interactions are mainly addressed to spectroscopists in both academia and industry. The introductory chapters provide the reader with the basics of NMR spectroscopy as a tool for the study of chiral compounds, and those more interested in the methods of chiral discrimination will benefit from the brief description of their common points and reasons why some of them may or may not work. In the following chapters, the book shows rapid progress in a newly emerging field of chirality-sensitive NMR, in particular, a search for effects that give direct information about the absolute configuration of a molecule. |
| chiral or achiral practice: Catalysis B. Viswanathan, 2002 Students contemplating careers in chemistry, whether in research, practice, or academia, obviously need a solid grounding in proper research methodology, reasoning, and analysis. However, there are few resources available that efficiently and effectively introduce these concepts and techniques and inspire students to undertake advanced research, particularly in the area of catalysis. Catalysis: Principles and Applications evolved out of a special, resoundingly successful short course for graduate students interested in catalysis. It covers nearly the entire gamut of the subject, from its fundamentals to its modern, applied aspects. The chapters were contributed by catalysis specialists from leading academic institutions, national laboratories and industrial R&D labs. Because they are based on the authors' lecture notes, each chapter is highly accessible and for the most part self-contained. Topics include various spectroscopic methods, biocatalysis, x-ray and thermal analysis, photocatalysis, and recent developments, such as solid acid catalysts, fine chemical synthesis, and computer-aided catalyst design. The book also contains discussions on a variety of modern applications, including environmental pollution control, petroleum refining, fuel cells, and monomolecular films. Logically presented, well-illustrated, and thoroughly referenced, Catalysis: Principles and Applications offers an outstanding basis for courses in catalysis. It not only imparts the fundamentals, synthesis, characterization, and applications of catalysis, but does so in a way that will motivate students to pursue more advanced studies and ultimately careers in the field. |

| chiral or achiral practice: Multi-Dimensional Liquid Chromatography Dwight R. Stoll, Peter W. Carr, 2022-12-30 Two-dimensional liquid chromatography (2D-LC) is finding increasingly wide application principally due to the analysis of mixtures of moderate to high complexity. Many industries are developing increasingly complex products that are challenging the separation capabilities of state-of-the-art 1D-LC and need new analytical methodologies with substantially more resolving power, and 2D-LC meets that need. This text, organized by two leaders in the field, establishes a sound fundamental basis for the principles of the technique, followed by a discussion of important practical considerations. The book begins with an introduction to multi-dimensional separations and a discussion of the history and development of the technique over the past 40 years, followed by several chapters that provide a theoretical basis for development of 2D-LC methods, including foundational concepts regarding separation complementarity, under-sampling, and dynamics of liquid chromatography separations. Instrumentation for 2D-LC is discussed extensively, including practical aspects such as interface selection and setup. Building on this foundation, two separate chapters are focused on method development for non-comprehensive and comprehensive separations, followed by a chapter dedicated to data analysis. Finally, applications of 2D-LC in several fields ranging from pharmaceutical analysis to polymer science are summarized. The book is an important resource for both students and practitioners who are already using 2D-LC or are interested in getting started in the field. Key Features: Demonstrates the conditions under which a 2D-LC method should be considered as an alternative to a 1D-LC method Establishes a sound fundamental basis of the principles of the technique, followed by guidelines for method optimization Provides a single source for technical knowledge advances and practical guidance described in recent literature Assists with the initial decision to develop a 2D-LC method Guides the reader in developing a high-quality method that meets the needs of their application |
