“…These deviations are a result of the distinct purities, water content, and handling of the samples, as well as the different measuring methods. On the other hand, a comparison with other ILs [18,41,42] and a conventional solvent (sulfonale) commonly used in aromatic/aliphatic separations [43,44] alkyl chain length is connected to a reduction of viscosity values as well as the sulfonatebased FILs reveal higher viscosity than carboxylate-based. The FIL with higher viscosity values ([P44414][C4F9SO3]) could lead to difficulties in mass transfer operations.…”

“…Finally, ionicity is also a relevant property for industrial process purposes and provides relevant insights on the mobility of fluid and evaluates the possibility of the formation of aggregates [45]. Ionicity is calculated based on the molar electrical conductivity (obtained from the experimental conductivity) and the dynamic viscosity of [18,41,42] and a common organic solvent (sulfolane) [43].…”

In this work, a set of novel fluorinated ionic liquids (FILs), based on different tetra-alkyl-phosphonium cations with perfluorobutanesulfonate and perfluoropentanoate anions, were synthesized and characterized in order to check their suitability to apply as engineering solvents. Thermophysical and thermal properties were both determined between 293.15 and 353.15 K, and the molecular volumes and free volumes and the coefficients of isobaric thermal expansion were determined from experimental values of refractive index and density. Lastly, the Walden plot was used to evaluate the ionicity of the novel FILs. The cytotoxicity of these compounds was also determined using the human hepatocellular carcinoma cells (HepG2) and the human colon carcinoma cells (Caco-2). Finally, the results were all discussed with the aim of understanding the behaviour of these compounds, considering the influence of the anion and the hydrogenated alkyl chain length. In summary, the new FILs synthesized in this work present adequate properties for their application in different industrial processes. Most of these compounds are liquid at room temperature with high decomposition temperatures. All phosphonium-based FILs have lower densities than conventional ionic liquids and common organic solvents, and the viscosity depends directly on the selected anion. Furthermore, the ionicity of FILs based on the sulfonate anion is higher than those based on the carboxylate anion. Finally, the phosphonium-based FILs have no significant effect on cellular viability at lower concentrations.

“…8 Mixtures of ionic liquids (ILs), also called “Double Salt ILs” (DSILs), 9 have gained increasing attention in recent years. 10–41 The concept of DSILs has been introduced since pure ILs already consist of two components with possibly antagonistic properties. Hence mixtures of two ILs experience a degree of variability, typically not accessible to mixtures of molecular liquids.…”

This work conducts a comprehensive modeling study on the viscosity, density, heat capacity, and surface tension of ionic liquid (IL)‐IL binary mixtures by combining the group contribution (GC) method with three machine learning algorithms: artificial neural network, XGBoost, and LightGBM. A large number of experimental data from reliable open sources is exhaustively collected to train, validate, and test the proposed ML‐based GC models. Furthermore, the Shapley Additive Explanations technique is employed to quantify the influential factors behind all the studied properties. Finally, these ML‐based GC models are sequentially integrated into computer‐aided mixed solvent design, process design, and optimization through an industrial case study of recovering hydrogen from raw coke oven gas. Optimization results demonstrate their high computational efficiency and integrability in solvent and process design, while also highlighting the significant potential of IL‐IL binary mixtures in practical applications.
