Assessment of COSMO-SAC Predictions for Solid–Liquid Equilibrium in Binary Eutectic Systems

“…Thus, the melting properties of thermally unstable substances were determined in the literature indirectly from experimental SLE data and assuming the ideal solution model (γ i = 1). However, as reported in the literature, ,,,− in salt-based ESs, a negative deviation from ideality is usually expected. Moreover, the melting properties of pure components and their activity coefficients in the liquid phase are interrelated .…”

Insights into the Chloride versus Bromide Effect on the Formation of Urea-Quaternary Ammonium Eutectic Solvents

“…Additionally, because quaternary ammonium salts with short alkyl chain lengths are known to decompose upon melting, 1 H and 13 C-NMR analysis of pure [N 2,2,2,2 ]Br and [N 2,2,2,2 ]Cl were performed after melting with slow and fast heating to verify the extent of degradation, along with the spectra of the salts at room temperature for comparison; Figures S4 and S5 of the Supporting Information. No differences in the spectra or new NMR signals were observed when melting [N 2,2,2,2 ]Cl with slow heating, when compared with the pure salt, indicating that no decomposition products are formed.…”

History repeats itself again: Will the mistakes of the past for ILs be repeated for DESs? From being considered ionic liquids to becoming their alternative: the unbalanced turn of deep eutectic solvents

“…28,29 More recently, water has also been proposed as a HBD and thus mixtures of DESs and water have been investigated to understand the composition up to which the DES's structure is maintained. [30][31][32][33][34] On the other hand, mixtures of imidazole-based ILs, [C 2 C 1 im]Cl, [C 4 C 1 im]Cl, [C 6 C 1 im]Cl, with a large variety of HBDs have been widely prepared and used in several applications. [35][36][37][38][39][40][41] The relevant role of the chloride anion, present in the IL, in the establishment of hydrogen bond donors in DESs has also been addressed.…”
