The conventional solvents used in chemical, pharmaceutical, biomedical and separation processes represent a great challenge to green chemistry because of their toxicity and flammability. Since the beginning of “the 12 Principles of Green Chemistry” in 1998, a general effort has been made to replace conventional solvents with environmentally benign substitutes. Water has been the most popular choice so far, followed by ionic liquids, surfactant, supercritical fluids, fluorous solvents, liquid polymers, bio-solvents and switchable solvent systems. Green Solvents Volume I and II provides a throughout overview of the different types of solvents and discusses their extensive applications in fields such as extraction, organic synthesis, biocatalytic processes, production of fine chemicals, removal of hydrogen sulphide, biochemical transformations, composite material, energy storage devices and polymers. These volumes are written by leading international experts and cover all possible aspects of green solvents’ properties and applications available in today’s literature. Green Solvents Volume I and II is an invaluable guide to scientists, R&D industrial specialists, researchers, upper-level undergraduates and graduate students, Ph.D. scholars, college and university professors working in the field of chemistry and biochemistry.

Green Solvents in Organic Synthesis Essential reference on replacing conventional solvents with greener alternatives in industrial chemicals synthesis and production A well-timed book promoting sustainability in synthesis and production of chemicals, Green Solvents in Organic Synthesis details various green solvents, solvent systems, and solubilization techniques, including their chemistry, physiochemical properties, performance, and distinct applications, presenting a greener approach to conventional solvents by replacing them with sustainable alternatives that have similarities in their reaction mechanisms. Edited by four highly qualified academics with significant research experience in the field, Green Solvents in Organic Synthesis includes information on: Water and liquid polymers (Polyethylene glycol PEG), Acetonitrile, DMSO, Dimethyl carbonate, Ionic liquids, and Supercritical fluids) Bio-based solvents (Cyrene, γ-Valerolactone (GVL), Lactic acid, 2-MeTHF) and deep eutectic solvents (DESs) Alcohols (MeOH, EtOH, i-PrOH, n-BuOH, t-BuOH, Ethylene glycol), ketones (Acetones, MEK, MIBK, Cyclohexanone), and esters (Methyl acetate, Ethyl acetate, i-PrOAc, n-BuOAc) Technical, economic, and environmental aspects of green solvents and how to maximize their reuse and recycling to alleviate pollution and reduce energy consumption For chemists in a variety of disciplines, Green Solvents in Organic Synthesis is an essential reference that provides foundational knowledge of green solvents, along with key features of each class of green solvent within the context of organic reactions for industrial and laboratory synthesis.

Everyone is becoming more environmentally conscious and therefore, chemical processes are being developed with their environmental burden in mind. This also means that more traditional chemical methods are being replaced with new innovations and this includes new solvents. Solvents are everywhere, but how necessary are they? They are used in most areas including synthetic chemistry, analytical chemistry, pharmaceutical production and processing, the food and flavour industry and the materials and coatings sectors. However, the principles of green chemistry guide us to use less of them, or to use safer, more environmentally friendly solvents if they are essential. Therefore, we should always ask ourselves, do we really need a solvent? Green chemistry, as a relatively new sub-discipline, is a rapidly growing field of research. Alternative solvents - including supercritical fluids and room temperature ionic liquids - form a significant portion of research in green chemistry. This is in part due to the hazards of many conventional solvents (e.g. toxicity and flammability) and the significant contribution that solvents make to the waste generated in many chemical processes. Solvents are important in analytical chemistry, product purification, extraction and separation technologies, and also in the modification of materials. Therefore, in order to make chemistry more sustainable in these fields, a knowledge of alternative, greener solvents is important. This book, which is part of a green chemistry series, uses examples that tie in with the 12 principles of green chemistry e.g. atom efficient reactions in benign solvents and processing of renewable chemicals/materials in green solvents. Readers get an overview of the many different kinds of solvents, written in such a way to make the book appropriate to newcomers to the field and prepare them for the 'green choices' available. The book also removes some of the mystique associated with 'alternative solvent' choices and includes information on solvents in different fields of chemistry such as analytical and materials chemistry in addition to catalysis and synthesis. The latest research developments, not covered elsewhere, are included such as switchable solvents and biosolvents. Also, some important areas that are often overlooked are described such as naturally sourced solvents (including ethanol and ethyl lactate) and liquid polymers (including poly(ethyleneglycol) and poly(dimethylsiloxane)). As well as these additional alternative solvents being included, the book takes a more general approach to solvents, not just focusing on the use of solvents in synthetic chemistry. Applications of solvents in areas such as analysis are overviewed in addition to the more widely recognised uses of alternative solvents in organic synthesis. Unfortunately, as the book shows, there is no universal green solvent and readers must ascertain their best options based on prior chemistry, cost, environmental benefits and other factors. It is important to try and minimize the number of solvent changes in a chemical process and therefore, the importance of solvents in product purification, extraction and separation technologies are highlighted. The book is aimed at newcomers to the field whether research students beginning investigations towards their thesis or industrial researchers curious to find out if an alternative solvent would be suitable in their work.

Solvents play an important role in organic synthesis. Most of the common organic solvents which have been used for organic synthesis include benzene, chloroform, toluene, carbon tetrachloride etc. Most of these are volatile (VOC) and have undesirable properties like toxicity or being harmful to the environment or may be obtained from non renewable petroleum sources. This book describes some of the most important green solvents, their merits and demerits. These green solvents include water, supercritical carbon dioxide, ionic liquids, polyethylene glycol and its solutions and the Florous Phase Technique. A large number of representative synthetic applications for each of the green solvents are described.
