Sodium Dithionite, Rongalite and Thiurea Oxides provides an in depth overview of historical and newly developed fields of application for important sulfur-containing reductants. It begins with an introduction into the structure and general properties of sodium dithionite, sodium hydroxymethanesulfinate (rongalite) and thiourea oxides. Following this there is analysis of their stability in different types of solutions, and reactions with both organic and inorganic compounds. Finally, there is description of the application of the reductants in industry, using examples of the textile, printing and paper industries, as well as in polymerization processes.Despite widespread practical application, the mechanism behind these compounds is not fully understood, due to their unusual structure and complex decomposition within solutions. This comprehensive review presents up-to-date findings to both academics and industrial chemists, aiming to increase knowledge and provide both fundamental and technical data dedicated to these relatively simple chemicals which have wide practical applications.

Much interest has been directed to the versatile possibilities of using lignocellulosic biomass resources (i.e., “renewable raw materials”) for the full-scale production of various chemicals and other bioproducts together with solid, liquid, and gaseous fuels. Introduces modern aspects and various technologies of lignocellulosic biomass conversion for producing chemicals, biofuels, and other products in a reader friendly way. Starting with fundamentals of biorefi nery, the author further describes chemical, biochemical, and thermal conversion approaches. In addition, the properties and biorefining principles of non-wood biomass feedstock

This book surveys the relatively new area of the synthesis of organic ligands when metal ions act as a template. In the last fifty years this field has undergone an explosive development, marked by a great amount of literature. The material in the book has been arranged according to the type of chemical reaction involved. In this frame, the basic principles of metal template reactions and the shape of the molecules are considered. Designed to satisfy the demands of students, young researchers doing their PhDs, and those working in the field of coordination chemistry, the book details the role of the metal ions and the specific properties of the formed complexes. Metal Mediated Template Synthesis of Ligands offers a comprehensive analysis with wide-ranging references and provides an extensive overview of research on metal-directed organic ligands over the past five decades. Contents: The Template Effect; Alkylation Reactions; Schiff Condensation; Mannich Condensation; Self Condensation of Nitriles; Self-Assembled Systems. Readership: Upper level undergraduates, graduate students, academics, researchers industrialists in inorganic, solid-state, supramolecular and organic chemistry.

This book deals with polypyrazolylborates (scorpionates), a class of ligands known since 1966, but becoming rapidly popular with inorganic, organometallic and coordination chemists since 1986, because of their versatility and user-friendliness. They can be readily modified sterically and electronically through appropriate substitution on the pyrazole ring and on boron, and have led to a number of firsts in coordination chemistry (first stable CuCO complex, first monomeric MgR complex, and many other such firsts). Their denticity can range from two to four, their “Bite” can be adjusted, and additional coordinating sites can be added to the pyrazolyl rings. Over 170 different scorpionate ligands are known today, and some are published for the first time in this book.The author, Swiatoslaw Trofimenko, discovered and developed this ligand system and has written several reviews on the subject. The book is intended as a reference work, placing at the researcher's command practically all of the over 1500 references on the subject up, and into 1999, organized both according to the ligand type and according to the metal or metalloid being coordinated. It acquaints the reader with the special features of this ligand system and permits an assessment of what has been done in a given sub-area, and of which areas remain relatively unexplored. It presents procedures for ligand synthesis, and also covers their use in catalysis and in the modelling of biologically active substances.

This book, written and edited by leading authorities from academia and industrial groups, covers both preventive- and curative-zeolite-based technologies in the field of chemical processing.The opening chapter presents the state of the art in zeolite science. The two subsequent chapters summarize the chemistries involved in the processes and the constraints imposed on the catalyst/adsorbent. Three major areas are covered: oil refining, petrochemicals and fine chemicals. A chapter on the (curative) use of zeolites in pollution abatement completes this overview.In the area of oil refining, a general lecture sets the scene for present and future challenges. It is followed by in-depth case studies involving FCC, hydrocracking and light naphtha isomerization. Also, an entire chapter is devoted to the often-overlooked subject of base oils.In the area of petrochemicals, the processing of aromatics and olefins is described and special attention is paid to the synergy between catalysis and separation on molecular sieves.

In terms of structural complexity, the natural world presents innumerable examples of stunning beauty and high functionality, usually with the minimum of material and energy expenditure. Materials chemists can harness these amazing structures as ready-made scaffolds on which to grow inorganic phases which replicate the underlying complexity, thereby producing materials with greatly enhanced physical properties. This book comprehensively describes the entire range of natural materials that have been used in this way and the inorganic phases which result from them. The book covers simple molecules such as cellulose and chitin, to large biological constructs such as bacterial proteins, viruses and pollen. Practically every inorganic material has been synthesized using biotemplating methods and the book reflects this, ranging from simple oxides and carbonates such as silica and calcite, to complex semi- and superconducting materials. The book also discusses the formation of these materials from a mechanistic point of view, thereby enabling the reader to better understand the processes involved in biotemplated mineralization.

This title takes researchers in as well as out of the field of metal-organic framework (MOF) and then guides them on a journey to rediscover and rethink how these designer coordination polymers will influence the realm of materials science. This book opens with a look at a deeply controversial issue, MOF stability, which has plagued many systems, but ultimately has led to better materials that proved to be more robust allowing them to be investigated for multiple applications. This book successfully highlights many of these useful applications that MOFs are well adapted for. Because MOF components, inorganic and organic, can combine the best of both chemical domains, MOFs will improve our environment by removing harmful contaminants from the air and water, reduce the energy required to perform chemical reactions, partition hard to separate molecular mixtures, and form the next-generation of magnetic and electronic materials. MOFs will eventually be used for everyday activities — for monitoring or reacting to changing conditions. Readers of this book can then take note and implement MOFs in their line of research.

Chapter contribution from John B Goodenough, Nobel Laureate in Chemistry 2019.This book provides a unique look at the chemistry and properties of complex metal oxides from the perspectives of some of the most active researchers on this class of materials. Applications of complex oxide materials are highly varied. Topics reviewed in this volume include solid-state battery research, the chemistry of transparent conductors, ternary uranium oxides, magnetic perovskites, non-linear optical materials, complex molybdenum-vanadium bronzes and other complex materials used in selective oxidation catalysis. It is written to serve as an introduction to the subject for and those beginning to work on these materials, particularly new graduate students.
