“…This method has successfully predicted the thermal stability of several IL binary mixtures [80,126,127]. However, for the mixture of [4C4MPyr][NTf2] and [C2MIM][EtSO4], the model cannot predict its thermal stability well, and this may be related to the strong interaction between [EtSO4] -anion and the other ions in the mixture [128].…”

Ionic liquids (ILs) are the safest solvent in various high-temperature applications due to their non-flammable properties. In order to obtain their thermal stability properties, thermogravimetric analysis (TGA) is extensively used to analyze the kinetics of the thermal decomposition process. This review summarizes the different kinetics analysis methods and finds the isoconversional methods are superior to the Arrhenius methods in calculating the activation energy, and two tools—the compensation effect and master plots—are suggested for the calculation of the pre-exponential factor. With both parameters, the maximum operating temperature (MOT) can be calculated to predict the thermal stability in long-term runnings. The collection of thermal stability data of ILs with divergent cations and anions shows the structure of cations such as alkyl side chains, functional groups, and alkyl substituents will affect the thermal stability, but their influence is less than that of anions. To develop ILs with superior thermal stability, dicationic ILs (DILs) are recommended, and typically, [C4(MIM)2][NTf2]2 has a decomposition temperature as high as 468.1 °C. For the convenience of application, thermal stability on the decomposition temperature and thermal decomposition activation energy of 130 ILs are summarized at the end of this manuscript.

“…In terms of thermodynamic properties, Vataščin and Dohnal reported the phase behavior of some aqueous solutions of [EMIM][TFES] and 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([EMIM][OTF]) under a variety of experimental conditions. Larriba et al studied phase behavior of {4-methyl- N -butylpyridinium bis(trifluoromethylsulfonyl)imide ([4bmpy][Tf 2 N]) + 1-ethyl-3-methylimidazolium ethylsulfate ([EMIM][EtSO 4 ])} and {[4bmpy][Tf 2 N] + [EMIM][TFES]} ionic liquid mixtures for the development of IL-based solvents.

The solubility of carbon dioxide (CO 2 ) in three different ionic liquids (ILs):and 1-benzyl-3-methylimidazolium 1,1,2,2-tetrafluoroethanesulfonate ([BNMIM][TFES]) were measured. Measurements were done at temperatures ranging from 303.2 to 373.2 K (323.2 to 373.2 K for [BNMIM][TFES]) at pressures from 0.80 to 36.80 MPa. Measured data show that pressure, temperature, and characteristics of cation of ILs ([EMIM], [BMIM], and [BNMIM]) affect its CO 2 solubility. We determined the CO 2 solubility of fixed CO 2 mole fractions for three ionic liquids. Among the three ILs, CO 2 solubility intensity was ranked. The Peng− Robinson equation of state, the conventional van der Waals one-fluid mixing rule, and the modified Lydersen−Joback−Reid method were used to correlate the experimental data. The average absolute deviations of pressure were 0.0164 for CO 2 + [EMIM][TFES], 0.0361 for CO 2 + [BMIM][TFES], and 0.0251 for CO 2 + [BNMIM][TFES] systems.

“…Similarly, insight into the characteristics of the ionic liquids that lead to nonideal behavior is key to developing ionic liquid mixtures that exhibit higher self-diffusion coefficients and ionic conductivity, and lower viscosity than those of the parent ionic liquids. Toward this end, a number of binary ionic liquid mixture systems have been investigated, both, experimentally − and with simulation-based ,,− approaches. For more examples of a number of ionic liquid mixture properties, the reader is directed to excellent reviews published by Welton and co-workers, and Rogers and co-workers .…”

Until very recently, task-specific ionic liquids have been designed by altering the chemistry of either the cation, anion, or both. An alternative approach, that is gaining considerable momentum, is to consider ionic liquids that are derived from mixing two different ionic liquids and varying the molar composition of such blends to exert precise control over the desired physicochemical and biological properties. As the number of ionic liquids that result from mixing is projected to be close to a billion, it is highly desirable to predict a priori whether ionic liquid mixtures can be considered as ideal solutions of their pure analogues. Toward this end, we employ molecular dynamics simulations to predict the density, molar volumes, excess molar volumes, self-diffusion coefficients, and ionic conductivities for 11 ionic liquid mixture systems as a function of mole fractions spanning the entire range of compositions of the constituent ionic liquids. The ionic liquid mixtures investigated here are 1-n-butyl-3-methylimidazolium [C4mim]+ chloride Cl– paired with [C4mim]+ acetate [CH3COO]−/[OAC]−, [C4mim]+ trifluoroacetate [CF3COO]−/[TFA]− and [C4mim]+ trifluoromethanesulfonate [CF3SO3]−/[TFS]−, and [C4mim][OAC] combined with [C4mim][TFA] and [C4mim][TFS]. The effect of change in the alkyl chain length on the thermophysical properties of ionic liquid mixtures containing anions as Cl––methylsulfate [MeSO4]−, and Cl––bis(trifluoromethanesulfonyl)imide [NTf2]− is evaluated by coupling with 1-ethyl-3-methylimidazolium [C2mim]+, 1-n-hexyl-3-methylimidazolium [C6mim]+, and 1-n-octyl-3-methylimidazolium [C8mim]+ cations. The deviation of the property trend from the linear mixing rule is discussed in terms of the difference in the properties of pure ionic liquid analogues.
