Available in PDF, EPUB and Kindle. Book excerpt: In diesem Buch werden wertvolle Informationen zur Chemie der Tragerreagenzien dargeboten, die bisher in der chemischen Literatur oder in entsprechenden Abstracts nur sehr schwer zu finden waren. Materialien und deren Praparation, sowie Analysemethoden und Fallstudien werden ausfuhrlich beschrieben. In der Entwicklung von Tragerreagenzien und deren potentieller Anwendung in der organischen Synthese gab es in jungster Zeit einen regelrechten Boom. Ein ganz entscheidender Vorteil von Tragerreagenzien ist ihre Umweltvertraglichkeit. Sie stellen somit eine interessante Alternative zu den konventionellen Reagenzien dar, die korrodierend, unwirtschaftlich und vor allem schwer zu entsorgen sind.
Download or read book Clean Synthesis Using Porous Inorganic Solid Catalysts and Supported Reagents written by James H Clark and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Other topics include the metal oxides and their physico-chemical properties in catalysis and synthesis; photochemistry of adsorbed molecules; and magnetic spin resonance methods and applications to oxide surfaces. The physico-chemical characterization of supported reagents; polymer-supported oxidations; and alumina and alumina-supported reagents are likewise deliberated. This text also covers the novel aluminophosphate-based molecular sieves, clay-activated isomerization reactions, anionic activation, and cationic reactions. This publication is beneficial to chemists and researchers conducting work on supported reagents.
Download or read book Chromium VI Reagents Synthetic Applications written by S. Sundaram and published by Springer Science & Business Media. This book was released on 2011-08-12 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromic acid and chromium oxide are the two versatile Cr(VI) oxidants known to organic chemists for decades. The introduction of the Core's reagent , viz: pyridinium chlorochromate, in 1975 followed by the publications on several Cr(VI) oxidizing agents containing the -onium chromates and halochromates in the last three decades have very much changed the chemistry of oxidations with Chromium VI. Several of these new reagents have been shown to be mild so that they can be handled easily and the reacton products may also be controlled. Some of them are highly selective oxidants for positions like allylic hydroxylic group, etc., and some other are highly regioselective. The information on more than 36 such reagents reported in various internationally reputed journals spanning about 280 references have been collected and provided in this book in such a manner that it will be very useful for professionals, researchers, teachers and graduate students working in organic synthesis.

Download or read book Porous Polymers written by Michael S. Silverstein and published by John Wiley & Sons. This book was released on 2011-02-14 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the various aspects of the porous polymer field into one volume. It not only presents a fundamental description of the field, but also describes the state of the art for such materials and provides a glimpse into the future. Emphasizing a different aspect of the ongoing research and development in porous polymers, the book is divided into three sections: Synthesis, Characterization, and Applications. The first part of each chapter presents the basic scientific and engineering principles underlying the topic, while the second part presents the state of the art results based on those principles. In this fashion, the book connects and integrates topics from seemingly disparate fields, each of which embodies different aspects inherent in the diverse field of porous polymeric materials.
Download or read book Clay Mineral Catalysis of Organic Reactions written by Benny K.G Theng and published by CRC Press. This book was released on 2018-07-27 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides insight into the working of clays and clay minerals in speeding up a variety of organic reactions. Clay minerals are known to have a large propensity for taking up organic molecules and can catalyse numerous organic reactions due to fine particle size, extensive surface area, layer structure, and peculiar charge characteristics. They can be used as heterogeneous catalysts and catalyst carriers of organic reactions because they are non-corrosive, easy to separate from the reaction mixture, and reusable. Clays and clay minerals have an advantage over other solid acids as they are abundant, inexpensive, and non-polluting.

Download or read book Heterogeneous Catalysis and Fine Chemicals written by J. Barrault and published by Elsevier. This book was released on 1988-08-01 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recession in the traditional heavy industries along with the development of advanced technologies in all the industrial countries has meant that the impact of heterogeneous catalysis in the synthesis of fine chemicals is becoming increasingly noticeable. The first International Symposium on Heterogeneous Catalysis and Fine Chemicals is to be seen in this perspective. Organised by the Laboratory of Catalysis in Organic Chemistry of the University of Poitiers within the framework of the International Symposia of the `Centre National de la Recherche Scientifique' (CNRS), the symposium provided an opportunity for contact between academic researchers and manufacturers, users (or potential users) of solid catalysts for fine chemical synthesis.Two panels of industrial and academic researchers - one on selective hydrogenation, the other on selective synthesis of substituted aromatics - showed that heterogeneous catalysis already plays a significant role in fine organic chemistry. The main topics of the symposium were introduced in six plenary lectures and three invited communications, maintaining a balance between the industrial and the academic points of view. Some 60 research papers were submitted from which the Scientific Committee selected the 35 communications (oral or poster) which fitted most closely the theme of the symposium. All are reproduced in full in this Proceedings volume.
