“…Type IV eutectic solvents are mixture of a metal chloride hydrate and an HBD. For a long time, the main division was into these four groups (type I-IV), but researchers have recently reported the existence of type V eutectic solvents, consisting of non-ionic molecular HBAs and HBDs (16).…”

“…Hydrophobic DESs can be divided into ionic and non-ionic ones, depending on their composition. Non-ionic DESs have an advantage over ionic DESs due to their cost-effectiveness and reusability (16). Another group of DESs includes magnetic DESs, which are obtained by adding a metal chloride to a previously prepared DES (i.e.…”

In recent years, Deep Eutectic Solvents (DESs) have attracted increasing attention in various scientific disciplines. Their unique properties, such as low toxicity, biodegradability, low cost and versatility, have made them an attractive alternative to conventional organic solvents. In pharmaceutical analysis, where the demand for environmentally friendly methods is growing, questions regarding whether DESs can replace organic solvents as "green solvents" have arisen. This paper explores the potential applications of DESs in drug analysis, and highlights the benefits and challenges they bring. Examples of the use of DESs in chromatographic techniques and in the extraction of drugs from various samples are presented. Additionally, research on the stability and toxicity of DESs in analytical applications is discussed. Based on the available data, it could be concluded that DESs have the potential to become an important component of analytical methods in pharmaceutical analysis and provide environmentally sustainable and efficient alternatives to conventional organic solvents. However, further research is needed to better understand their properties and optimize their application in drug analysis.

“…The authors stressed the highly tunable character of the eutectic point of these mixtures in the dependence of carboxylic acids’ chain lengths. The factors influencing the phase equilibrium in deep eutectic solvents also were presented in the work by Crema et al [ 24 ]. The authors described a number of HDES using 1,10-phenanthroline as the HBA.…”

Hydrophobic deep eutectic solvents (HDES) are widely used as extractants. Usually, when preparing HDES, only the extraction ability of one component is taken into account, with the second serving as an “inert” component, whose effect on the extraction process is not taken into account. The present study demonstrates the possibility of controlling the selectivity of a hydrophobic deep eutectic solvent based on trioctylphosphine oxide (TOPO) by varying the substance that acts as a hydrogen bond donor, but which does not have an extractive ability. In the course of the work, the influence of the “inert” component on the physicochemical and extraction properties of HDES was confirmed by experimental, spectroscopic, and also calculation methods. A number of phenols with different structural features were chosen as the HDES’ hydrogen bond donors to modify: phenol (Ph), para-tert-butylphenol (PTBP) and thymol (Th). Using the example of separation of the Sm/Co pair, the influence of the structure of a hydrogen bond donor on the extraction ability of a hydrophobic deep eutectic solvent was established, where the degree of extraction of Sm (III) increased in the series Th:TOPO < PTBP:TOPO < Ph:TOPO. HDES based on TOPO and phenols can potentially be used to separate Sm and Co from the process leach solutions generated during the hydrometallurgical processing of waste SmCo magnets.
