Ionic liquids (ILs) have attracted significant attention from researchers in various fields as a result of their unique properties. As new and important applications are identified for these materials, there is also a drive to develop methods for accessing a wider range of ILs. However, despite this demand, only a few techniques have so far been reported and, more importantly, general but efficient processes for IL synthesis were lacking. Thus, it would be beneficial to devise a cost-effective, environmentally friendly means of producing a wide variety of pure ILs. The present work demonstrates a general purpose electrodialysis approach to the formation of highly pure ILs, based on the formation of nine different ILs from various combinations of cations and anions. In each case, the IL was obtained with a purity of >99%. This method offers the advantages of avoiding the use of hazardous organic solvents and eliminating tedious and costly purification processes. Unlike conventional methods, this membrane-based technol. also prevents the generation of side products. Mixed ILs have many potential applications, and the present technique readily generates various mixed ILs based on a simple adjustment of the applied current.

Rotjanasuworapong, Kornkanok published the artcileElectromechanical responses of agarose ionogels as highly soft and compliant actuators, Computed Properties of 79917-90-1, the publication is European Polymer Journal (2022), 111059, database is CAplus.

Ionogels have been of interest as an alternative electroactive material for soft actuator applications, as they can maintain the shape and size under ambient conditions. Herein, the phys. cross-linked agarose ionogels were fabricated via a solvent casting method by using 1-butyl-3-methylimidazolium chloride ([Bmim][Cl]) as the ionic liquid The electro-actuation responses were investigated in terms of agarose contents and elec. field strengths. For the electromech. responses, the electrostriction shows two distinct behaviors dependent on agarose contents: at the high agarose content of 12.0%volume/volume, the storage modulus relative response (ΔG’/G’0) was the pos. value of 0.06, known as the pos. electrostriction; at the low agarose contents of 4.0%volume/volume and 8.0%volume/volume, the ΔG’/G’0 were neg. definite at -0.11 and -0.06, resp. These behaviors occurred from the plasticizing [Bmim][Cl] mols. which were able to hinder the agarose intermol. interactions. For the electro-induced bending behaviors, the AG-[Bmim][Cl] Ionogel_4.0%volume/volume revealed the highest deflection distance and dielectrophoresis force (F_d) due to its lower initial rigidity and the polarizations from the [Bmim][Cl], moisture, and agarose structures, resp. Comparing with other bio-polymeric hydrogels and ionogels, the present AG-[Bmim][Cl] Ionogels are shown here to possess relatively low electrostrictive stresses but high dielectrophoresis force d.; both are essential features for utilizing in soft actuator applications.

Kowalska, Dorota published the artcileInteraction of ionic liquids with human serum albumin in the view of bioconcentration: a preliminary study, Formula: C8H15ClN2, the publication is Chemical Papers (2022), 76(4), 2405-2417, database is CAplus.

Bioaccumulation potential is critical in PBT and risk assessment of chems. However, for ionic liquids (ILs), this aspect remains neglected. It is especially important to fill this gap, because for this group of compounds, existing data confirm their risk of being environmentally persistent and toxicity. Moreover, considering preliminary reports on the interactions of ILs with lipids, it may be assumed that ILs have a higher potential for bioaccumulation than indicated by previous estimations built upon octanol-water partition coefficients Moreover, the bioconcentration of ionizable chem. compounds may also be strongly related to plasma protein contents. Therefore, in this work, the affinity of a set of imidazolium cations and organic anions, and their combination to human serum albumin (HSA) was determined The obtained results reveal that both cations and anions can be strongly bound to HSA, and blood proteins might play an important role in overall bioaccumulation. Furthermore, it was observed that HSA binding properties towards IL cations depend on the hydrophobicity of cations. The obtained data also provide indication that cation-anion interaction may affect ILs ions affinity to HSA.

Elterman, V. A. published the artcileFeatures of aluminum electrodeposition from 1,3-dialkylimidazolium chloride chloroaluminate ionic liquids, Formula: C8H15ClN2, the publication is Journal of Molecular Liquids (2022), 118693, database is CAplus.

The mechanism of aluminum electrodeposition from acidic 1-butyl-3-methylimidazolium chloride chloroaluminate ionic liquids ([BMIm]Cl ILs) is studied over a wide range of the molar ratio of AlCl₃ to [BMIm]Cl (N) at 30°C. The findings for AlCl₃-[BMIm]Cl and AlCl₃-1-ethyl-3-methylimidazolium chloride ([EMIm]Cl) are analyzed and compared in order to identify dependences common for 1,3-dialkylimidazolium chloride ILs. Limiting currents were detected on the cathodic polarization curves at the aluminum | ionic liquid interface. Limiting currents are caused by the Al₂Cl^–₇ anions diffusion to the electrode surface. The limiting c.d. values for AlCl₃-[BMIm]Cl are lower (i_lim, 1.1 ≤ N leq 2.0 = 1.17 – 12.36 mA•cm^-2) than for AlCl₃-[EMIm]Cl (i_lim, 1.1 ≤ N leq 2.0 = 1.81 – 25.37 mA·cm^-2). It is shown that anion AlCl-4 can be reduced to metallic aluminum at cathodic overpotentials above 1.5 V. The diffusion coefficient of Al₂Cl-7 in AlCl₃-[BMIm]Cl (7.4•10-7 cm²•s^-1) is lower than in AlCl₃-[EMIm]Cl (9.3•10-7 cm²•s^-1) and is unaffected by aluminum chloride concentration in either system.

Wolf, Silke published the artcileRoom-Temperature Synthesis of [BMIm][Sn₅O₂Cl₇] with _∞¹(Sn₂OCl₂) Strands in a Saline [BMIm][SnCl₃] Matrix, Application of 3-Butyl-1-methyl-1H-imidazol-3-ium chloride, the publication is Inorganic Chemistry (2022), 61(9), 4018-4023, database is CAplus and MEDLINE.

The novel tin(II) oxychloride [BMIm][Sn₅O₂Cl₇] (BMIm: 1-butyl-3-methylimidazolium) is obtained by room-temperature reaction (25°C) of black SnO and SnCl₂ in [BMIm]Cl/SnCl₂ as ionic liquid The title compound can be described to be composed of noncharged, infinite inf¹(Sn₂OCl₂) strands, which are embedded in a saline matrix of [BMIm]⁺ and [SnCl₃]^–. The inf¹(Sn₂OCl₂) strands consist of a backbone of edge-sharing OSn₄/₂ tetrahedra, which represent one-dimensional strands cut out of the layer-type structure of SnO. In [BMIm][Sn₅O₂Cl₇] the inf¹(Sn₂OCl₂) strands, which mimic a 1D semiconductor, are terminated by chlorine atoms, whereas they are interconnected by oxygen in the 2D semiconductor SnO. The view of the noncharged inf¹(Sn₂OCl₂) strands in a saline [BMIm][SnCl₃] matrix is validated by dissolution experiments Thus, electron microscopy and Raman spectroscopy show a deconstruction of [BMIm][Sn₅O₂Cl₇] single crystals after treatment with CHCl₃ with a dissolution of [BMIm][SnCl₃], the formation of SnCl₂ needles, and tin oxide as a solid remain.

Hernandez, Elisa published the artcileUniversal and low energy-demanding platform to produce propylene carbonate from CO₂ using hydrophilic ionic liquids, Application of 3-Butyl-1-methyl-1H-imidazol-3-ium chloride, the publication is Separation and Purification Technology (2022), 121273, database is CAplus.

Ionic liquids (ILs) have been extensively proposed as efficient catalysts to promote CO₂ cycloaddition reaction to epoxides for producing cyclic carbonates. Recently, liquid-liquid extraction with water as an enhancer approach to regenerate ILs and to purify the product was proposed, since it reduces energy consumption and enhances the neat catalytic activity of the IL due to hydroxyl groups of water. In this work, a comprehensive sample of homogeneous IL catalysts proposed in the literature is exptl. evaluated both in the catalytic step and in its separation by liquid-liquid extraction with water, to demonstrate the universality of the proposed reaction-separation proposal for hydrophilic ILs. Then the complete processes for CO₂ conversion to propylene carbonate were modelled using Aspen Plus to compare the catalyst/product separation efficiency and the specific energy consumption using liquid-liquid extraction and distillation-based platforms. The energy consumption is significantly lower using liquid-liquid platform (1.1-1.3 kWh/kg_PC) than distillation one (2.4-3.1 kWh/kg_PC). It is concluded that hydrophilic ionic liquids, as those formed by [EtOHmim] cation and halide anions, are promising catalysts since they allow: (i) reducing the process energy consumption due to their high catalytic activity and (ii) full catalyst recovering, even at high catalyst loadings, by improving the water extractive properties for IL separation from PC.

The object of this work focuses, on the one hand, on the development of the Wilson model for electrolytes, temperature-dependent parameters, and, on the other, tests the model and its accuracy in the prediction of ternary VLE data from few exptl. data points. The exptl. data reported in the literature are used to determine the model parameters proposed in this work for the ethanol-water binary system. The obtained interaction parameters are then used for the correlation and prediction of VLE data for five ternary systems composed of ethanol, water and different ionic liquids with different percentages at atm. pressure (101.32 kPa). We have made the prediction of ternary VLE data, ionic liquid-containing ternary systems, from temperature-dependent binary interaction parameters, adjusted by using some ternary VLE data coupled with binary VLE data. The obtained results are in good agreement with the data reported in the literature.

Chen, Yuqiu published the artcileMachine learning for the prediction of viscosity of ionic liquid-water mixtures, HPLC of Formula: 79917-90-1, the publication is Journal of Molecular Liquids (2022), 118546, database is CAplus.

In this work, a nonlinear model that integrates the group contribution (GC) method with a well-known machine learning algorithm, i.e., artificial neural network (ANN), is proposed to predict the viscosity of ionic liquid (IL)-water mixtures After a critical assessment of all data points collected from literature, a dataset covering 8,523 viscosity data points of IL-H₂O mixtures at different temperature (272.10 K-373.15 K) is selected and then applied to evaluate the proposed ANN-GC model. The results show that this ANN-GC model with 4 or 5 neurons in the hidden layer is capable to provide reliable predictions on the viscosities of IL-H₂O mixtures With 4 neurons in the hidden layer, the ANN-GC model gives a mean absolute error (MAE) of 0.0091 and squared correlation coefficient (R²) of 0.9962 for the 6,586 training data points, and for the 1,937 test data points they are 0.0095 and 0.9952, resp. When this nonlinear model has 5 neurons in the hidden layer, it gives a MAE of 0.0098 and R² of 0.9958 for the training dataset, and for the test dataset they are 0.0092 and 0.9990, resp. In addition, comparisons show that the nonlinear ANN-GC model proposed in this work has much better prediction performance on the viscosity of IL-H₂O mixtures than that of the linear mixed model.
