Special Issue Information

Dear Colleagues,

Increasing concerns about the environmental and health impact of some conventional solvents has turned researchers’ attention toward finding alternative green solvents. One class of promising green solvents, Deep Eutectic Solvents (DES), is usually prepared from natural, inexpensive, and biodegradable materials. DES are formed by mixing two or more components, where the resulting eutectic mixtures show a large depression in melting temperature compared to the pure compounds. As the literature shows, they have been studied extensively in recent years and show great potential in many applications, such as in separation technologies, the extraction of natural compounds, as well as the enhancement of solubility and the bioactivity of active pharmaceutical ingredients (API). However, studies investigating the applicability of these solvents at the process scale, their recycling, and their economic feasibility have yet to be published. In addition, the selection of DES candidates for a particular application is currently primarily done by trial-and-error. These important topics have not yet been covered, mainly due to lack of experimental data regarding their basic physiochemical properties, most importantly, their melting temperature.

The aim of this Special Issue is to invite experts from the fields of chemistry, (bio)chemical engineering, and pharmaceutical science in order to provide more insight into the properties and applications of DES. We are looking forward to receiving experimental and theoretical investigations concerning the structure of DES in liquid as well as solid phases, their use in the recovery and separation of (active) compounds from natural sources and synthetic liquid mixtures, their application in product formulation, and DES recycling strategies.

The anodic dissolution of bulk metallic copper was conducted in ionic liquids (ILs)—a deep eutectic solvent (DES) ((CH3)3NC2H4OH) comprised of a 1:2 molar ratio mixture of choline chloride Cl (ChCl), and ethylene glycol (EG)—and imidazolium-based [...] Read more.
The anodic dissolution of bulk metallic copper was conducted in ionic liquids (ILs)—a deep eutectic solvent (DES) ((CH3)3NC2H4OH) comprised of a 1:2 molar ratio mixture of choline chloride Cl (ChCl), and ethylene glycol (EG)—and imidazolium-based ILs, such as C4mimCl, using electrochemical techniques, such as cyclic voltammetry, anodic linear sweep voltammetry, and chronopotentiometry.To investigate the electrochemical dissolution mechanism, electrochemical impedance spectroscopy (EIS) was used. In addition to spectroscopic techniques, for instance, UV-visible spectroscopy, microscopic techniques, such as atomic force microscopy (AFM), were used. The significant industrial importance of metallic copper has motivated several research groups to deal with such an invaluable metal. It was confirmed that the speciation of dissolved copper from the bulk phase at the interface region is [CuCl3] and [CuCl4]2− in such chloride-rich media, and the EG determine the structure of the interfacial region in the electrochemical dissolution process. A super-saturated solution was produced at the electrode/solution interface and CuCl2 was deposited on the metal surface. Full article
