Book

Cover Alicyclic Chemistry
Alicyclic Chemistry provides an overview of the study of non-aromatic organic compounds made up of one or more carbocyclic rings. Such compounds, which range from simple ring systems to complex bridged and polycyclic structures, provide a framework for the understanding of many concepts which underlie organic chemistry. The topics covered include a discussion of the stability and conformational behaviour of carbocyclic ring systems, and the factors which control the choice of synthetic methods and reactivity of such compounds. Many aspects of alicyclic chemistry provide an important framework for a proper understanding of the behaviour of organic molecules.

The next chapter covers mechanistic organometallic chemistry. Chapter Three is related to hydroformylation and related reactions. The chapter that follows examines acetic acid and acetyl chemicals. The next two chapters look at nylon intermediates: buta- 1,3-diene hydrocyanation and olefin oligomerization and polymerization. The final chapter is about fine chemicals manufacture.

Book

Cover Aquatic Environmental Chemistry
Aquatic Environmental Chemistry covers the composition and underlying properties of both freshwater and marine systems and, within this framework, explains the effects of acidity, complexation, oxidation and reduction processes, and sedimentation. Equilibrium inorganic chemistry underlies the composition and properties of the aquatic environment and provides a sound basis for understanding both natural geochemical processes and the behaviour of inorganic pollutants in the environment. The format adopted for the book consists of two parallel columns. The inner column is the main body of the book and can be read on its own. The outer column is a source of useful secondary material where comments on the main text, explanations of unusual terms, and guidance through mathematical steps are to be found. A wide range of examples to explain the behaviour of inorganic species in freshwater and marine systems are used throughout.

Book

Cover Aqueous Acid-Base Equilibria and Titrations
Aqueous Acid-Base Equilibria and Titrations uses new theoretical developments which have led to more generalized approaches to equilibrium problems; these approaches are often simpler than the approximations which they replace. Acid-base problems are readily addressed in terms of the proton condition, a convenient amalgam of the mass and charge constraints of the chemical system considered. The graphical approach of Bjerrum, Hȩgg, and Sillén is used to illustrate the orders of magnitude of the concentrations of the various species involved in chemical equilibria. Based on these concentrations, the proton condition can usually be simplified, often leading directly to the value of the pH. In the description of acid-base titrations, a general master equation is developed. The text provides a continuous and complete description of the entire titration curve, which can then be used for computer-based comparison with experimental data. Graphical estimates of the steepness of titration curves are also developed, from which the practicality of a given titration can be anticipated. Activity effects are described in detail, including their effect on titration curves. The discussion emphasizes the distinction between equilibrium constants and electrometric pH measurements, which are subject to activity corrections, and balance equations and spectroscopic pH measurements, which are not. Finally, an entire chapter is devoted to what the pH meter measures, and to the experimental and theoretical uncertainties involved.

Book

Cover The Basis and Applications of Heterogenuous Catalysis
The Basis and Applications of Heterogeneous Catalysis covers a wide range of topics within this field. Catalysis is one of the most important technologies in our modern world. We depend on it to produce materials, such as plastics, from oil; we depend on it to produce fuel to power our cars; we depend on it to remove the pollutants emitted from the engines of those cars; we even depend on it for the functioning and growth of our own bodies. It is therefore highly important that we ask ourselves the question, 'What is catalysis?' This book does exactly that, concentrating on the most important type of catalysis for industry, namely heterogeneous catalysis. The book is split into three sections, dealing with the fundamentals of adsorption and reaction at surfaces, the nature of heterogeneous catalysts and their synthesis, and the applications of this technology in the modern world.

Book

Cover Bifunctional Compounds
Bifunctional Compounds outlines some of the methods used to prepare bifunctional compounds and then surveys the chemistry of some of the more important classes. Most important organic molecules contain more than one functional group, and very often the interaction between these groups determines the chemical and biological behaviour of the compounds. Individual chapters look at the preparation of bifunctional compounds, reactions of dienes, of diols, of hydroxy- and aminocarbonyl compounds, of dicarbonyl compounds, and of unsaturated carbonyl compounds. The text also covers enamines, enol ethers, enolates, allyl compounds, and cyclization and polymerization.

Book

Cover Biocoordination Chemistry
Biocoordination Chemistry introduces this field. The role of the transition metals in biological systems is of great interest to chemists: the chemical properties of these metals often define the biological function of the proteins and systems these metals are found in. This book introduces a number of topics: the transport and storage of metals, their functions in dioxygen interactions, electron-transfer, and enzyme activity; the therapeutic uses of coordination compounds; and the role that small-molecule models can play in advancing our knowledge of the structure and function of transition metals contained in metallobiosites.

Book

Cover Chemical Instrumentation
Chemical Instrumentation introduces chemists to some of the building blocks and devices that make up the most important instruments used in industry and research. Instrumentation, often of a highly sophisticated kind, lies behind many of the most interesting aspects of contemporary chemistry. Some techniques—such as NMR—owe their existence to electronic instrumentation; others have been made simpler, more reliable, and more precise. Yet undergraduates reading chemistry often have only the most rudimentary understanding to be performed. Simple measuring devices are discussed before the introduction of the constituent elements of more complex devices, and emphasis is given to the enhancement of signal-to-noise ratios, which often lies at the heart of some of the most demanding measurements in the chemical sciences.
