Organic Solvents

In most cases, every chemist must deal with solvent effects, whether voluntarily or otherwise. Since its publication, this has been the standard reference on all topics related to solvents and solvent effects in organic chemistry. Christian Reichardt provides reliable information on the subject, allowing chemists to understand and effectively use these phenomena. 3rd updated and enlarged edition of a classic 35% more contents excellent, proven concept includes current developments, such as ionic liquids indispensable in research and industry From the reviews of the second edition: "...This is an immensely useful book, and the source that I would turn to first when seeking virtually any information about solvent effects." —Organometallics

Use this database to instantly locate the compound you need! This electronic database covers 564 of the most common solvents used in industry, academic research, and general commerce. These organic solvents find applications as carriers for paints, medications, cleaning agents, and a host of other active ingredients. Health hazards and safety guidelines are covered, including the limiting values for airborne exposure, carcinogenicity status, flammability, and various official hazard ratings. With this flexible and powerful electronic reference, the user can easily and quickly select a solvent that meets his or her criteria for a particular application. For example, the user can specify desired physical properties and required safety levels and get back a list of solvents that conform to all the requirements. Searches ranging from the very simple (one or two specifications) to the very complex (a large combination of requirements that must be met) are easily performed with this database.

Metal Oxide Nanoparticles in Organic Solvents discusses recent advances in the chemistry involved for the controlled synthesis and assembly of metal oxide nanoparticles, the characterizations required by such nanoobjects, and their size and shape depending properties. In the last few years, a valuable alternative to the well-known aqueous sol-gel processes was developed in the form of nonaqueous solution routes. Metal Oxide Nanoparticles in Organic Solvents reviews and compares surfactant- and solvent-controlled routes, as well as providing an overview of techniques for the characterization of metal oxide nanoparticles, crystallization pathways, the physical properties of metal oxide nanoparticles, their applications in diverse fields of technology, and their assembly into larger nano- and mesostructures. Researchers and postgraduates in the fields of nanomaterials and sol-gel chemistry will appreciate this book’s informative approach to chemical formation mechanisms in relation to metal oxides.

Green Chemistry is a philosophy that has been implemented in different areas of science. Organic solvents allow recovery of bioactive compounds without contaminating the environment, since they are non-petroleum solvents and cheap. This book focuses on the properties, applications and health effects of organic solvents. Chapter One examines the chemistry and food applications of green solvents. Chapter Two analyses the use of green solvent in the extraction of bioactive compounds. Chapter Three gives a thermochemical description of the stabilising/destabilising effect of organic solvent molecules on the stability of model enzyme (bovine pancreatic α-chymotrypsin) to elucidate what intermolecular processes produce the main effect on the stability and functioning of the enzymes at high and low water content in organic liquids. Chapter Four reviews a novel experimental method was proposed to study the stability of enzymes in water-organic mixtures. Chapter Five discusses the metrology of exposure to organic solvents in the shoe industry of Sfax, Tunisia.

In recent years the choice of a given solvent for performing a reaction has become increasingly important. More and more, selective reagents are used for chemical transformations and the choice of the solvent may be determining for reaching high reaction rates and high selectivities. The toxicity and recycling considerations have also greatly influenced the nature of the solvents used for industrial reactions. Thus, the development of reactions in water is not only important on the laboratory scale but also for industrial applications. The p- formance of metal-catalyzed reactions in water for example has led to several new hydrogenation or hydroformylation procedures with important industrial applications. The various aspects of organic chemistry in water will be prese- ed in this book. Recently, novel reaction media such as perfluorinated solvents or supercritical carbon dioxide has proven to have unique advantages leading to more practical and more efficient reactions. Especially with perfluorinated solvents, new biphasic catalyses and novel approaches to perform organic reactions have been developed. These aspects will be examined in detail in this volume. Finally, the performance of reactions in the absence of solvents will show practical alternatives for many reactions. More than ever before, the choice of the solvent or the solvent system is ess- tial for realizing many chemical transformations with the highest efficiency. This book tries to cover the more recent and important new solvents or solvent systems for both academic and industrial applications.

We believe this to be the first monograph devoted to the physicochemical properties of solutions in organic solvent systems. Although there have 1 been a number of books on the subject of non-aqueous solvents - 4, they have been devoted, almost entirely, to inorganic solvents such as liquid ammonia, liquid sulphur dioxide, etc. A variety of new solvents such as dimethylformamide, dimethylsulphoxide and propylene carbonate have become commercially available over the last twenty years. Solutions in these solvents are of technological interest in connection with novel battery systems and chemical synthesis, while studies of ion solvation and transport properties have fostered academic interest. This monograph is primarily concerned with electrolytic solutions although discussion of non-electrolyte solutions has not been excluded. We have deliberately omitted consideration of the important area of solvent extraction, since this has been adequately covered elsewhere. Our contributors were asked to review and discuss their respective areas with particular reference to differences in technique necessitated by use of non-aqueous solvents while not reiterating facts well-known from experience with aqueous solutions. We have striven to build their contributions into a coherent and consistent whole. We thank our con tributors for following our suggestions so ably and for their forebearance in the face of our editorial impositions.

Written by highly renowned and experienced authors, this is the only reference on the application of solvents as reagents. Clearly structured, the text describes various methods for the activation and reaction of these small molecules, highlighting the synthetic opportunities as well as process-oriented advantages. To this end, all relevant types of solvents are covered separately and emphasized with numerous synthetic examples, while taking care to explain applications so as to avoid undesired side reactions. The result is a unique resource for every synthetic chemist and reaction engineer in industry and academia working on the methodical optimization of synthetic transformations.
