Book excerpt: En un peu plus d'un demi-siècle, les zéolithes (appelées aussi tamis moléculaires) ont conquis une position clé dans notre vie quotidienne. Ces nanomatériaux ont des applications diverses et variées, allant de l'échange des cations durs en détergence au séchage des gaz et des solutions organiques, à la séparation par tamisage moléculaire et à la catalyse. Cette dernière application est la plus importante : les zéolithes sont en effet de remarquables catalyseurs qui permettent la production sélective et propre des molécules oléfiniques et benzéniques pour la Chimie, de carburants et lubrifiants de qualité, de précurseurs de médicaments, etc. et la destruction de polluants gazeux. Ce livre comprend 14 chapitres. Les trois premiers décrivent les principales zéolithes commerciales, leur synthèse et la caractérisation des propriétés qui ont fait leur succès dans la catalyse sélective de nombreuses réactions. Les trois suivants montrent sur des exemples démonstratifs que leur sélectivité exceptionnelle provient du réseau régulier de leurs cages et canaux de taille moléculaire contenant des centres actifs de caractéristiques bien définies. Les huit autres chapitres présentent en détail les grands procédés du raffinage du pétrole (craquage, hydroisomérisation, hydrocraquage), de la pétrochimie (production d'alkyl benzéniques, conversion du méthanol en éthylène et propène, oxydation et ammoximation, etc.), de la chimie fine et de la dépollution, utilisant des zéolithes comme catalyseurs. L'accent est mis sur la diversité des réactions et de leurs mécanismes (catalyse acide, basique, acidobasique, d'oxydation, bifonctionnelle) et sur l'apport économique et environnemental important des catalyseurs zéolithiques. Des annexes introduisent les notions fondamentales et appliquées indispensables aux lecteurs non spécialistes. Cet ouvrage est destiné aux chercheurs, débutants ou confirmés, universitaires ou industriels, du domaine de la catalyse. Il peut aussi permettre aux Professeurs d'IUT, de licence, de master, d'écoles d'Ingénieurs, etc. d'illustrer de façon claire le rôle des nanomatériaux dans la Chimie industrielle moderne.

This book was released on 2012-09-06 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The work presented in Thomas M. Gøgsig's thesis deals with the discovery of new metal-catalyzed transformations ranging from Kumada-, Heck- and Suzuki-type reactions. The thesis starts with a formidable introduction to Pd-catalyzed cross-coupling reactions. New results have been obtained on: (i) Pd-catalyzed 1,2-migration reactions, (ii) Pd-catalyzed Heck reactions employing heteroaromatic tosylates, (iii) Ni-catalyzed Heck reactions, and (iv) Pd-catalyzed carbonylative Heck reaction. Metal-catalyzed cross-coupling reactions are today a highly competititve field (the 2010 Nobel Prize in Chemistry was awarded "for palladium-catalyzed cross couplings in organic synthesis", the 2001 and 2005 Nobel Prizes in closely related fields). Thomas M. Gøgsig obtained new results in his thesis that will help to improve the outcome of catalytic processes and improve their scope. The results will thus become key references for tomorrow's new applications. All chapters include insightful discussions and in-depth descriptions of the key principles of these new discoveries.

Available in PDF, EPUB and Kindle. Book excerpt: Catalysts are increasingly used by chemists engaged in fine chemical synthesis within both industry and academia. Today, there exists a huge choice of high-tech catalysts, which add enormously to the repertoire of synthetic possibilities. However, catalysts are occasionally capricious, sometimes difficult to use and almost always require both skill and experience in order to achieve optimal results. This series aims to be a practical help for advanced undergraduate, graduate and postgraduate students, as well as experienced chemists in industry and academia working in organic and organometallic synthesis. The series features: * Tested and validated procedures. * Authoritative reviews on classes of catalysts. * Assessments of all types of catalysts. * Expertise from the Leverhulme Centre for Innovative Catalysis, Liverpool, UK. The review section in the first volume of the series contains a report by Stanley M. Roberts on the integration of biotransformations into the catalyst portfolio. The procedure section contains a wide variety of synthetic protocols, such as epoxidations of unsaturated ketones and esters, asymmetric reductions of carbon-oxygen double bonds, asymmetric hydrogenations of carbon-carbon double bonds and other types of reaction. The featured catalysts include a wide range of different materials such as poly-D-leucine, D-fructose-based dioxiranes, oxaborolidine borane, some important titanium and ruthenium complexes as well as baker's yeast. For each reaction there are one or several detailed protocols on how to prepare and employ the various catalysts.

Available in PDF, EPUB and Kindle. Book excerpt: This brief summarizes the role of certain catalysts and associated processes that are involved in the reduction or elimination of hazardous substances from wastewater and the exploitation of renewable raw materials. The authors begin by providing a summary of the most recent developments in catalysts used in the advanced oxidation of organic pollutants in aqueous phase. Advanced Oxidation Processes (AOPS) are described in terms of homogeneous and heterogeneous catalysts. Some emphasis is placed on the role nanocatalysts, perovskite-type catalysts, and green catalysts play in several AOPs such as Fenton Chemistry, photocatalytic oxidation, and the hybrid technologies that combine different processes. Catalyst preparation, characterization, reaction chemistry, and process technology are described. Specific wastewater case studies which illustrate the role of these catalysts in AOPs completes the brief.

Book excerpt: Le livre Chimie organométallique et Catalyse est l’ouvrage de référence pour cette science-pivot à la frontière de la synthèse organique, de la science du vivant et de la catalyse. Il couvre tous les aspects : historiques, structuraux, orbitalaires, de réactivité, catalytiques, biologiques ainsi que les applications en synthèse organique et les grands procédés industriels. Cette vision globale va des métaux des groupes principaux aux lanthanides et actinides, en passant par les métaux de transition. De même, la section sur la catalyse s’étend des phénomènes d’hydrogénation jusqu’à la catalyse hétérogène, cruciale pour l’industrie. En fin de chapitre, se trouvent des résumés, des exercices pour travailler en autoformation ou en groupe avec les solutions en fin d’ouvrage. 500 références complètent un texte rédigé avec un rare souci pédagogique. Les derniers résultats de la recherche sont présents, mais le livre reste accessible aussi bien aux débutants qu’aux lecteurs de niveau avancé. Les lecteurs seront d’abord les étudiants de chimie et chimie physique (L3, M2, ingénieur) mais aussi les universitaires, chercheurs, enseignants, professionnels de l’industrie. Didier Astruc a eu un parcours brillant au CNRS et au MIT à Cambridge avant de devenir professeur à l’Université de Bordeaux et à l’Institut Universitaire de France. Il accumule les publications (plus de 400), les prix et distinctions (Grand Prix le Bel, Royal Society of Chemistry Fellow, Humboldt Prize, Iberdrola Prize...). Il est membre de nombreuses académies européennes. Ses thèmes de recherche préférés sont les systèmes avec réservoir d’électrons, les complexes métalliques, les nanoparticules et la catalyse... Il est aussi un pédagogue reconnu qui nous offre ici un ouvrage rare, de haut niveau et en même temps accessible.

Book excerpt: This book provides a comprehensive review of a new generation of selective oxidation titanosilicate catalysts with the MWW topology (Ti-MWW) based on the research achievements of the past 12 years. It gives an overview of the synthesis, structure modification and catalytic properties of Ti-MWW. Ti-MWW can readily be prepared by means of direct hydrothermal synthesis with crystallization-supporting agents, using dual-structure-directing agents and a dry-gel conversion technique. It also can be post-synthesized through unique reversible structure transformation and liquid-phase isomorphous substitution. The structural conversion of Ti-MWW into the materials usable for processing large molecules is summarized. Taking advantage of the structure diversity of the lamellar precursor of Ti-MWW, it can be fully or partially delaminated, and undergo interlayer silylation to obtain a novel structure with larger porosity. In the selective oxidation (alkene epoxidation and ketone/aldehyde ammoximation) with hydrogen peroxide or organic peroxide as an oxidant, the unique catalytic properties of Ti-MWW are described in comparison to conventional titanosilicates such as TS-1 and Ti-Beta.
