This volume summarises and reviews the enormous progress made over the past two decades in solid acids and bases, with emphasis on fundamental aspects and chemical principles. In recent years many new kinds of solid acids and bases have been found and synthesized. The surface properties (in particular, acidic and basic properties) and the structures of the new solids have been clarified by newly developed measurement methods using modern instruments and techniques. The characterized solid acids and bases have been applied as catalysts for diversified reactions, many good correlations being obtained between the acid-base properties and the catalytic activities or selectivities. Recently, acid-base bifunctional catalysis on solid surfaces is becoming a more and more important and intriguing field of study.It has been recognized that the acidic and basic properties of catalysts and catalyst supports play an important role in oxidation, reduction, hydrogenation, hydrocracking, etc. The effect of the preparation method and the pretreatment conditions of solid acids and bases on the acidic and basic properties, the nature of acidic and basic sites and the mechanism regarding the generation of acidity and basicity have been elucidated experimentally and theoretically. On the basis of the accumulated knowledge of solid acids and bases, it is now possible to design and develop highly active and selective solid acid and base catalysts for particular reactions. The chemistry of solid acids and bases is now being related to and utilized in numerous areas including adsorbents, sensors, cosmetics, fuel cells, sensitized pressed papers, and others. The information presented in this book will therefore be of interest to a wide-ranging readership.

Solid Acids and Bases: Their Catalytic Properties reviews developments in the studies of acidic and basic properties of solids, including the efficacy and special characteristics of solid acid and base catalysts. This book discusses the determination of basic and acidic properties on solid surfaces and relationship between acid strength and acid amount. The structure and acid-base properties of mixed metal oxides and correlation between acid-base properties and catalytic activity and selectivity are also deliberated. This publication is useful to professional chemists and graduate students in the fields of organic, inorganic and physical chemistry, petroleum chemistry and catalysis, including readers interested in the acidic and basic properties on solid surfaces.

Because of the great importance of acid catalysis in the petrochemical industry, extensive research has been carried out during the last 30 years concerning the fundamental and applied aspects of catalysis by acids. In contrast, base-catalyzed reactions have received little attention in heterogeneous catalysis. The aim of this symposium was to evaluate our knowledge of the important area of acid and base catalysis and to cover a broad range of solids, zeolite chemistry being only one aspect of heterogeneous catalysis.

Solids that possess acidic properties on their surfaces function as catalysts just like liquid acids, such as sulfuric acid and hydrochloric acid. By using solid acid catalysts, chemical processes become more productive and more environmentally friendly. In fact, solid acids are being used in many industrial chemical processes from the largest chem

Reactive, but not a reactant. Heterogeneous catalysts play an unseen role in many of today's processes and products. With the increasing emphasis on sustainability in both products and processes, this handbook is the first to combine the hot topics of heterogeneous catalysis and clean technology. It focuses on the development of heterogeneous catalysts for use in clean chemical synthesis, dealing with how modern spectroscopic techniques can aid the design of catalysts for use in liquid phase reactions, their application in industrially important chemistries - including selective oxidation, hydrogenation, solid acid- and base-catalyzed processes - as well as the role of process intensification and use of renewable resources in improving the sustainability of chemical processes. With its emphasis on applications, this book is of high interest to those working in the industry.

Base-Catalyzed Reactions of Hydrocarbons and Related Compounds focuses on the use of bases as catalysts for the conversion of hydrocarbons and related compounds. In order to emphasize the broad scope of base-catalyzed reactions, examples dealing with the conversion of non-hydrocarbons are given. Comprised of 14 chapters, this book begins with a historical overview of base-catalyzed conversions of hydrocarbons, followed by a discussion on the isomerization of olefins, acetylenes, and allenes, as well as the dimerization and oligomerization of hydrocarbons. The reader is then introduced to a variety of reactions, including those between aromatic hydrocarbons and olefins and between alkylpyridines and alkenylpyridines; homogeneous carbon-carbon addition reactions; and reactions of aprotic solvents with olefins. Subsequent chapters explore carbon-carbon addition of olefins with miscellaneous compounds; addition of ammonia, amines, and anilines to olefinic hydrocarbons; hydrogenation and oxygenation; dehydrogenation, aromatization, and hydrogen transfer; and dehydration of alcohols. This monograph will be of interest to chemists.

Mechanical methods of the activation of chemical processes are currently widely used for the synthesis of various compounds. The present monograph deals with the development of a novel approach to mechanochemical synthesis based on reactions of solid acids, bases, hydrated compounds, crystal hydrates, basic and acidic salts. This method has been called soft mechanochemical synthesis. The monograph includes the papers published by the present authors. They describe the results of their investigations n the last two decades. New theoretical and experimental data on kinetics and mechanism of soft mechanochemical reactions in the mixtures of compounds mentioned above to give complex oxide compounds are presented. The description of new high energetic and high efficient mills providing effective occurrence of these reactions is delivered. The possibilities of applying soft mechanochemical synthesis for materials used in catalysts, material science, electronics, etc., are discussed. The advantages of the method proposed in comparison with other methods are demonstrated. The monograph is designed for researchers, engineers and technicians engaged in chemical and ceramic industry, for scientists and students specialized in the area of development, and application of new materials.

An acid that is stronger than the acid strength of 100% sulphuric acid is known as a superacid. Environmental concerns about the use of toxic liquid superacids and liquid inorganic acids in the transformation of hydrocarbons provide an impetus for a search of stable and more environmentally friendly solid acid catalysts. This book examines an important opportunity related to green chemistry where solid superacids lead to new gas- and liquid-solid phase reactions, which are environmentally benign processes in the chemical industry.

The importance of solid base catalysts has come to be recognized for their environmentally benign qualities, and much significant progress has been made over the past two decades in catalytic materials and solid base-catalyzed reactions. The book is focused on the solid base. Because of the advantages over liquid bases, the use of solid base catalysts in organic synthesis is expanding. Solid bases are easier to dispose than liquid bases, separation and recovery of products, catalysts and solvents are less difficult, and they are non-corrosive. Furthermore, base-catalyzed reactions can be performed without using solvents and even in the gas phase, opening up more possibilities for discovering novel reaction systems. Using numerous examples, the present volume describes the remarkable role solid base catalysis can play, given the ever increasing worldwide importance of "green" chemistry. The reader will obtain an overall view of solid base catalysis and gain insight into the versatility of the reactions to which solid base catalysts can be utilized. The concept and significance of solid base catalysis are discussed, followed by descriptions of various methods for the characterization of solid bases, including spectroscopic methods and test reactions. The preparation and properties of base materials are presented in detail, with the two final chapters devoted to surveying the variety of reactions catalyzed by solid bases.
