Book excerpt: Phase Transfer Catalysis: Principles and Techniques outlines the theory, mechanism, and kinetics of the phase transfer catalysis (PTC) process. This book surveys the principal reaction types that have employed the PTC, including the typical experimental procedures for preparing catalysts and conducting representative types of chemical reactions. This compilation discusses the transfer of anions from aqueous to organic phases, macrocyclic ethers as phase transfer catalysts, halide displacement reactions, and Darzen's reaction with chloroacetonitrile. The dihalocarbene insertion reactions into C-H bonds, Wittig reaction with aqueous sodium hydroxide, and phase transfer catalyzed oxidation and reduction reactions are also elaborated. This text likewise covers the deuterium exchange of active hydrogens and thiolation with organic thiocyanates. This publication is beneficial to chemists and students studying the principles and techniques related to PTC.

This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of phase transfer catalysis is a tribute to the chemists involved in process development research. Phase transfer catalysis is a solution to numerous cost and yield problems encountered regularly in industrial laboratories. In fact, much of the early work in this area was conducted by industrial chemists although the work was not labelled phase transfer catalysis at the time. We certainly do not intend to minimize the contributions of academic chemists to this field, but it is an unalterable fact that much of the early understanding and many of the early advances came from industrial laboratories. A special tribute is due to Dr. Charles Starks of the Continental Oil Company. By the mid sixties, Starks had formulated the principles of phase transfer catalysis and had applied for patents on many reactions that others were later to examine in somewhat greater detail. His mechanistic model of phase transfer catalysis still stands up well today and is a model for much of the thinking in this area. It is fitting that Starks suggested the name "phase transfer catalysis" by which the whole field is now known. We wish to thank a number of people who have aided us in many ways in the preparation of this volume. We very much appreciate the helpful discussions and insights provided by Drs. Henry Stevens and Andrew Kaman of PPG Industries in Barberton, Ohio. We also thank Dr. L. A.

Download or read book Handbook of Phase Transfer Catalysis written by Y. Sasson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phase transfer catalysis is a sophisticated chemical technique which can be used to perform a variety of chemical reactions under mild conditions and with improved control. Since the concept was developed, both the theoretical and practical synthetic applications have seen considerable development, to the point where the technique can be applied to many areas of chemistry. Thus, phase transfer methods are now utilized in many applications, from research chemistry to full-scale production, where the benefits of faster, cleaner and more selective reactions are required. In this new book, the editors have brought together a range of contributors, each of whom is working at the forefront of the technology, to provide a clear, concise and ahtoritative review of this important area of chemistry. Industrial and academic chemists working on the synthesis, scale-up, production or analysis of a wide range of chemical products will find this book an essential reference on phase transfer technology.

Available in PDF, EPUB and Kindle. Book excerpt: Since 1971 when useful working concepts for the technique of phase-transfer catalysis (PTC) were introduced, the understanding, development, and applica tions of this method for conducting organic reactions has expanded exponentially. PTC has brought vast new dimensions and options to chemists and chemical engineers. From its use in less than ten commercial processes in 1975, PTC use has increased so that in the early 1990s it is involved in more than 600 industrial applications to manufacture products valued at between 10 and 20 billion U.S. dollars. PTC is widely used for simple organic reactions, steps in synthesis of pharmaceuticals, agricultural chemicals, perfumes, ftavorants, and dyes; for specialty polymerization reactions, polymer modifications, and monomer synthe sis; for pollution and environmental control processes; for analysis oftrace organic and inorganic compounds; and for many other applications. Often, PTC offers the best (and sometimes only) practical technique to obtain certain products. The authors experience in teaching a short course on phase-transfer catalysis has shown to us that a newcomer to PTC can easily be frustrated and confused by the large amount of information available in the literature and in patents. The purpose of this book, therefore, was to bring this information together in a logical and user-friendly way, without sacrificing matters of scholarly and fundamental importance.

Book excerpt: Fruit de l'expérience des auteurs au sein du module d'enseignement Systèmes réactifs et procédés industriels de l'Ensic, École nationale supérieure des industries chimiques, de Nancy, ce manuel rassemble les notions fondamentales de cinétique et de catalyse nécessaires aux ingénieurs chimistes ou de génie chimique. Le plan général de Cinétique et catalyse suit la démarche logique du cinéticien : - mesure de la vitesse, - détermination de la loi de vitesse, - élucidation du mécanisme réactionnel homogène et/ou hétérogène. Complémentaire - mais indépendant- de Génie de la réaction chimique du Pr J. Villermaux, cet ouvrage fournit aux élèves ingénieurs et étudiants des 2ème et 3ème cycles universitaires des exemples nombreux et variés. Dans cette nouvelle édition, un chapitre a été ajouté, il traite de la modélisation cinétique des réactions complexes en phase gazeuse, telles qu'on les rencontre actuellement, entre autres dans tous les phénomènes de combustion et en chimie atmosphérique (formation des polluants, destruction de la couche d'ozone, changements climatiques, ). Interviennent dans cette modélisation, des méthodes informatiques de conception automatique de mécanismes réactionnels et de simulation numérique ainsi que des méthodes d'estimation de grandeurs thermodynamiques ou cinétiques basées sur des approches semi-empiriques ou dérivées de la chimie quantique. Ce chapitre montre, ainsi, comment les concepts fondamentaux, présentés dans les premiers chapitres, peuvent être utilisés pour aborder la modélisation cinétique des réactions complexes en phase gazeuse, d'intérêt industriel.
