Описание: This book looks at new ways of tackling the problem of separating reaction products from homogeneous catalytic solutions. The new processes involve low leaching supported catalysts, soluble supports such as polymers and dendrimers and unusual solvents such as water, fluorinated organics, ionic liquids and supercritical fluids. The advantages of the different possibilities are discussed alongside suggestions for further research that will be required for commercialisation. Unlike other books, in addition to the chemistry involved, the book looks at the process design that would be required to bring the new approaches to fruition. Comparisons are given with existing processes that have already been successfully applied and examples are given where these approaches are not suitable. The book includes: - New processes for the separation of products from solutions containing homogeneous catalysts- Catalysts on insoluble or soluble supports вЂ“ fixed bed catalysts - continuous flow or ultrafiltration- Biphasic systems: water - organic, fluorous - organic, ionic liquid вЂ“ organic, supercritical fluids (monophasic or biphasic with water, organic or ionic liquid)- Comparisons with current processes involving atmospheric or low temperature distillation- Consideration of Chemistry and Process Design- Advantages and disadvantages of each process exposed- Consideration of what else is need for commercialisation

Описание: Provides studies in catalyst deactivation that play a major role in the identification of the real catalytic system, the structure and texture of the solid, often in a metastable state, as it is operated in the industrial reactor. These studies allow the identification of the experimental conditions which preserve this active and selective state.

Sample preparation is an everyday part ofan Analytical Chemist's workflow and this booksupports researches in optimizing their work, byoutlining the latest preparation techniquesfrom around the globe. Answers are provided to such questions as - How do I automate a procedure? Who are the vendors that offer options? How do I work to reduce matrix interferences? Could I do this procedure on-line instead of in a batch manually? Who are the vendors offering automation options? Who are the 96-well SPE plate manufacturers? What sorbent materials are available in the market? How do I use a cation exchange resin? What has been published on micro-sampling techniques? What is a molecularly imprinted polymer? Can liquid-liquid extraction be used in a plate format? How do I seal microplates after elution? Can I elute analytes in tiny microliter volumes? How do I evaporate eluates in a microplate? How can I use my LEAP auto-sampler to perform sample prep? Which microplate can work with 50 microliter sample volumes? Addressing the workflow pain points of productivity and extraction process efficiency, this bookoutlines exactly how to make methods more productive and how to develop and optimize methods to be as efficient as possible. No other book provides this step-by-step approach coupled with a thorough explanation of the technology, making it the go-to reference book in the field for analytical scientists in industry. "

Описание: Highlights the rapid evolution of the surface science of catalysts. Focuses on multi-technique strategies for studying catalytic reactions and catalytic materials. Discusses new developments in electron microscopy, laser-induced desorption, magnetic methods, and new vibrational characterization techniques.
Описание: As in the study of transition metal complexes in solution, molecular spectroscopic methods - principally the infrared, ultraviolet/visible and electron spin resonance spectroscopies - have played key roles in establishing the concepts of coordination chemistry occurring at the surfaces of solids. This book describes the development of the principals of coordination chemistry of oxide surfaces using analyses of data obtained by these methods. The nature, properties, concentration of the surface adsorption centers and their influence on the character of interaction with different molecules are investigated. The book commences with ancount of the basic theoretical principles and experimental techniques of the various spectroscopy methods, with special attention devoted to in situ measurements where the oxide or catalyst sample is in contact with the adsorbate or the reactant. A detailed account is presented of the methods for characterizing the oxidation state and degree of coordination of surface cations and oxygen anions by the adsorption of probe molecules. The complexation of many inorganic, organometallic and organic molecules with different oxide systems is critically examined, and a classification of formed surface compounds, based on the interaction with definite type of adsorption centers, is given. Possible mechanisms of numerous catalytic reactions, including the transformation of organic molecules over acidic catalysts via the carboionic mechanism, are discussed using the spectroscopic identifications of reaction intermediates. A comprehensive analysis of the literature on the interpretation of the spectra of surface compounds on oxides is presented. This highly illustrated and extensively referenced volume is intended for specialists working in the fields of surface physical chemistry, surface and materials sciences, and adsorption phenomena and is essential reading for those involved in the heterogeneous catalysis by transition metal-oxides.
