A useful guide to the fundamentals and applications of deep eutectic solvents Deep Eutectic Solvents contains a comprehensive review of the use of deep eutectic solvents (DESs) as an environmentally benign alternative reaction media for chemical transformations and processes. The contributors cover a range of topics including synthesis, structure, properties, toxicity and biodegradability of DESs. The book also explores myriad applications in various disciplines, such as organic synthesis and (bio)catalysis, electrochemistry, extraction, analytical chemistry, polymerizations, (nano)materials preparation, biomass processing, and gas adsorption. The book is aimed at organic chemists, catalytic chemists, pharmaceutical chemists, biochemists, electrochemists, and others involved in the design of eco-friendly reactions and processes. This important book: -Explores the promise of DESs as an environmentally benign alternative to hazardous organic solvents
-Covers the synthesis, structure, properties (incl. toxicity) as well as a wide range of applications
-Offers a springboard for stimulating critical discussion and encouraging further advances in the field Deep Eutectic Solvents is an interdisciplinary resource for researchers in academia and industry interested in the many uses of DESs as an environmentally benign alternative reaction media.

1.1 Introduction

At the beginning of this century, deep eutectic solvents (DESs) appeared as a new class of green solvents [1] and they are considered as a new class of ionic liquids (ILs) due to their similar characteristics and properties. However, they are two different types of solvents. An ionic liquid is an association of a cation and an anion. In contrast, DES is a combination of two or more solids that form, through hydrogen bond formation, a eutectic liquid mixture at a temperature lower than the melting point of each compound that is part of the DES [2]. The intersection of the eutectic temperature and the eutectic composition gives the eutectic point (E in Figure 1.1). E is the point where the eutectic mixture is a unique composition of two or more nonmiscible phases of solid components that after association form a liquid at a defined temperature.

The interest in DESs increased considerably at industrial or academic level as shown by the number of publications dedicated to DESs. This is due to their great convenience of synthesis, their low production costs by using safe components, and the...
