Coordination Chemistry in Non-Aqueous Solutions


Book Description

Considerable attention has been focussed on non-aqueous chemistry in the last decade and this situation has arisen no doubt from a realization of the vast application of this branch of chemistry. Within this field much energetic work has been channelled into the determination of the coordination chemistry of tran sition metals in these solvent 8ystems. Elaborate experimental techniques have been developed to discover, in particular, the magnetic and spectral properties of complex compounds, and the theoretical background of such systems has been expanded to corroborate, as far as possible, the experimental results. This text has, however, a different bias from many books currently available on this branch of chemistry, and is designed to be a survey of known facts on many of the non-aqueous solvents currently in use mainly in the field of halogen chemistry, together with a discussion of these facts in the light of accepted principles. As such, it is hoped to close a gap in the literature of which many workers and advanced students in this field will be aware. The treatment is meant to be selective rather than completely comprehensive and must unevitably reflect some of the special interests of the author.




Solvation, Ionic and Complex Formation Reactions in Non-Aqeuous Solvents


Book Description

Solvation, Ionic and Complex Formation Reactions in Non-Aqueous Solvents: Experimental Methods for their Investigation presents the available methods and their particular value in investigating solutions composed of non-aqueous solvents. This book is composed of 10 chapters and begins with a brief description of the complexity of the interactions possible n solutions. The subsequent chapters deal with a classification of the solvents and empirical solvent strength scales based on various experimental parameters, together with various correlations empirically describing the solvent effect. Other chapters present the methods for the purification of solvents and ways of checking their purity, as well as the individual results achieved during investigations of the solvent effect, particularly the general regularities recognized. The remaining chapters provide a review of the coordination chemistry of non-aqueous solutions. This book will prove useful to analytical and inorganic chemists.




The Chemistry of Nonaqueous Solvents V4


Book Description

The Chemistry of Nonaqueous Solvents, Volume IV: Solution Phenomena and Aprotic Solvents focuses on the chemistry of nonaqueous solvents, with emphasis on solution phenomena and aprotic solvents such as tetramethylurea, inorganic acid chlorides, cyclic carbonates, and sulfolane. This book is organized into seven chapters and begins with an overview of the theory of electrical conductivity and elementary experimental considerations, along with some of the interesting research on nonaqueous solvents. It then turns to a discussion on hydrogen bonding phenomena in nonaqueous systems as probed by four spectroscopic techniques; the different methods used in studying redox systems in nonaqueous solvents such as potentiometry and steady state diffusion methods; and the use of tetramethylurea as a nonaqueous medium for chemical reactions and chemical investigations. The reader is also introduced to inorganic acid chlorides of high dielectric constant, with special reference to antimony trichloride, and preparation methods for cyclic carbonates including vinylene carbonate, ethylene carbonate, propylene carbonate, and butylene carbonate. The book concludes with a chapter on sulfolane, focusing on its preparation and purification, physical properties, and toxicology. This book will be of interest to chemists who want to know more about nonaqueous solvents.

Solvent Effects on Chemical Phenomena


Book Description

Solvent Effects on Chemical Phenomena, Volume I discusses the developments in the understanding of solvent effects on chemical phenomena in solution. This five-chapter volume begins with a discussion on the general concepts of various solvation types, including positive and negative, inner and outer sphere, and mixed component. The subsequent chapter deals with the determination of the actual solvation number for single ions. A short list of the total effective hydration numbers of electrolytes determined from temperature dependence of proton shifts is also provided in this chapter. Another chapter presents a number of examples of the unusual properties of certain mixed aqueous systems. The solvent effects on reaction rates and mechanisms are highlighted in the concluding chapter. This chapter also covers various types of solvents, such as protic and dipolar aprotic. The enthalpy and entropy of activation in salvation and the Finkelstein reactions are also discussed. Research chemists and scientists, teachers, and students with courses in solution chemistry will greatly benefit from this volume.
