The book "Ionic Liquids," edited by Douglas Inman and David G. Lovering, is a collection of essays and lectures that focus on the properties and applications of ionic liquids. The editors, who are chairmen of the Electrochemistry and Molten Salts Discussion Groups of the Chemical Society, organized a conference in 1978 that led to the compilation of this volume. The book aims to bridge the gap between aqueous chemists and those working with molten salts, fostering a broader understanding of the concepts and methods in these fields. The content covers a wide range of topics, including the transport properties of molten salts and electrolyte solutions, the role of water in molten salts, the purification of high-temperature ionic solvents, hydrogen in ionic liquids, and the solution chemistry of water in melts. It also explores the chemical and electrochemical aspects of sulfur and sulfide electrochemistry in ionic liquids, as well as the studies of molten mixtures of halides and chalcogenides. The book highlights the importance of ionic liquids in various applications such as energy generation, storage, fuel cells, and materials recycling, driven by the finite nature of fossil fuel resources and the increasing emphasis on efficiency, recycling, and ecological soundness. The editors encourage a selective and personal approach in the chapters, emphasizing the most relevant aspects of the field to stimulate new interest and awareness across the spectrum of solution concentrations. The book is intended to be a valuable resource for researchers and practitioners in both aqueous solution and molten salt chemistry and electrochemistry.The book "Ionic Liquids," edited by Douglas Inman and David G.
