The densities and viscosities of binary mixtures of 1-ethyl-3-methylimidazolium heptachlorodialuminate and tetrachloroaluminate ionic liquids with different molar compositions were measured by high-precision vibrating tube densimeter and automated microviscometer from 293.15 to 353.15 K. On this basis, the excess molar volumes and excess viscosities of binary mixtures were also calculated for the first time. All the experimental data were well fitted by the empirical equations. According to the results of computational calculations, enhanced molecular symmetry and molar concentration of heptachlorodialuminate anion usually lead to higher density. The hydrogen bonding among ions is confirmed as one of the most important structural parameters in determining the viscosity of ionic liquids. It shows that Lewis acidic 1-ethyl-3-methylimidazolium chloroaluminate can be treated as the classic binary mixtures of heptachlorodialuminate and tetrachloroaluminate ionic liquids. Looser packing and/or weaker interionic interaction probably occurs after the formation of binary mixtures. The results and conclusions of this work will help to promote future research and application of chloroaluminate ionic liquids.

“…They increase the packing of the structure and as a consequence, the density of the real mixture is higher than the theoretical one [11]. Beyond the minimum an increase of the molar fraction of DMSO, the excess of the molar volume tends again to zero because the presence of the DMSO or liquid solvents causes the attraction forces between the IL ions reduce, producing a certain expansion of the fluids [34,44]. In Figure 7 the excess molar volumes of the mixtures with molar fractions of 0.241 and 0.140 of DMSO are represented as a function of temperature at various pressures.…”

In this work, densities of dimethyl sulfoxide + 1-allyl-3-methylimidazolium chloride mixtures have been experimentally determined with a vibrating tube densimeter. Densities were measured at temperatures between 293.15 and 373.15 K and molar fractions of dimethyl sulfoxide xDMSO = 0, 0.05 0.1, 0.15, 0.25, 0.5, 0.75, 0.9 and 1 at pressures in the range P = [0.1, 35] MPa. It was found that density increases with ionic liquid concentration and with pressure and decrease with temperature. Excess molar volumes were calculated resulting in negative values with a maximum of non-ideality at DMSO concentration of xDMSO = 0.5. The excess molar values were less negative at high pressures. At T = 330 K a maximum in the excess molar values was observed at several concentrations. Density was correlated as a function of temperature, pressure and concentration with an average relative deviation of 0.12%.

“…DBU can also directly deprotonate some weak proton donors, such as fluorinated alcohols, imidazoles, pyrrolidinones, or phenols, to afford protic DBU ionic liquids. Scheme 3 shows some examples of anion functionalized ionic liquids, which were prepared through the neutralization reaction of DBU and imidazole, pyrazole, phenol, and 1,2,4-triazole, respectively [8][9][10].…”
