Deep eutectic solvents (DESs) formed by hydrogen bond donors and acceptors are a promising new class of solvents. Both hydrophilic hydrophobic binary DESs readily absorb water, making them ternary mixtures, small water content is always inevitable under ambient conditions. We present thorough study typical DES 1:2 mole ratio tetrabutyl ammonium chloride decanoic acid, focusing on the effects low caused absorbed vapor, using multinuclear NMR techniques, molecular modeling, several other physicochemical techniques. Already very contents cause dynamic nanoscale phase segregation, reduce solvent viscosity fragility, increase self-diffusion coefficients conductivity, enhance local dynamics. Water interferes with hydrogen-bonding network between ions carboxylic acid groups solvating them, which enhances self-correlation ion pair formation chloride. Simulations show that component molar can be varied, an effect internal structure. The water-induced changes in physical properties beneficial for most prospective applications but creates acidic aqueous nanophase high halide concentration, may have chemically adverse effects.

Deep eutectic solvents (DESs) are multicomponent designer that exist as stable liquids over a wide range of temperatures. Over the last two decades, research has been dedicated to developing noncytotoxic, biodegradable, and biocompatible DESs replace commercially available toxic organic solvents. However, most formulated until now hydrophilic disintegrate via dissolution on coming in contact with aqueous phase. To expand repertoire green solvents, hydrophobic (HDESs) were prepared an alternative. The hydrophobicity is consequence constituents can be modified according nature application. Due their immiscibility, HDESs induce phase segregation solution thus utilized extracting medium for multitude compounds. Here, we review literature reporting usage extraction various compounds metal ions from solutions absorption gases like CO2. We also discuss techniques currently employed processes. have delineated limitations might reduce applicability these discussed examples how behave reaction media.

Deep eutectic solvents (DESs) are a class of ionic liquid analogues that have received heightened research attention in recent years. These binary or ternary mixtures composed quaternary salts, metal organic compounds exhibit hydrogen bond donating and accepting behaviours within the DES system, forming network results melting point depression. The facile preparation DESs coupled with virtually unlimited combination components enables large number unique to be produced, characterized, applied; accordingly, highly tailorable can prepared for specific applications. Numerous applied studies utilized DESs; however, current fundamental knowledge physicochemical phase equilibria properties is relatively limited compared wide spectrum possible formulations. Furthermore, available reporting encompasses multitude parameters, from density conductivity more niche such as vapour pressure acoustic properties. Therefore, comprehensive review compiles evaluates works documenting required improve our understanding their prospective applications, identify gaps this critical area. Accordingly, paper aims act reference on illuminate efforts dedicated foundational

Deep Eutectic Solvents (DES) are emerging as environmentally friendly and effective alternatives in membrane technology, offering a sustainable edge over traditional solvents. This review compiles the latest advancements incorporation of DES into polymeric systems for diverse separation processes, including ultrafiltration (UF), microfiltration (MF), nanofiltration (NF), reverse osmosis (RO), forward (FO), pervaporation, distillation (MD). Special attention is devoted to preparation methods involving Non-Solvent Induced Phase Separation (NIPS), Interfacial Polymerization (IP), electrospinning. Notable developments include integration various types, such Thin-Film Composite (TFC) NF FO, Supported Liquid Membranes (SLMs) asymmetric mixed matrix membranes UF. The introduces classification either hydrophilic or hydrophobic, revealing their respective roles applications. A critical examination hydrogen bond donors (HBD) acceptors (HBA) offers insights mechanisms behind DES-based membranes. central challenge addressed complex behavior leaching within membranes, which has varying implications on performance, efficiency, purity filtration processes. While some studies have shed light stability intentional components enhance functionality, research notably sparse when it comes specific issue water highlights an existing void suggests direction future studies. comprehensive serves roadmap further development wider industrial adoption technologies while identifying both strengths areas improvement.

Abstract One of the highlights green chemistry is development techniques and procedures with low environmental impact. In last years, deep eutectic solvents (DES) have become an important alternative to conventional organic solvents. For a period ionic liquids provoked remarkable interest, but they been displaced by DES because show easier preparation methods, lower prices, many them are biodegradable compatible biological systems. addition, adjustable physicochemical properties, high thermal stability, volatility water. this paper reviewed state art use paying special attention role reaction media in synthesis.
