The ionic liquid (IL) of 1-hexyl-3-methylimidazolium acetate is widely used in chemical and bio-chemical processes. In this work, due to the high viscosity of IL, the promising chemicals (i.e., N, N-dimethylacetamide, N, N-dimethylformamide, and dimethyl sulfoxide) were selected as the additives to lower IL viscosity. The thermophysical properties of density and viscosity for IL with solvents were measured using a digital vibrating U-tube densimeter and an Ubbelohde capillary viscometer from 303.15 to 338.15 K at atmospheric pressure (0.0967 MPa), respectively. The influences of the solvents on the thermophysical properties of ionic liquid were quantitatively studied. Furthermore, based on the measurement values, the derived properties of excess molar volumes, thermal expansion coefficient, and the energy barrier were calculated, and the results showed that the mixture composition had great impact on excess volume change and viscosity. The hard-sphere model was employed to reproduce the viscosity. The infrared spectroscopy was performed to study the chemical structure to further understand the interactions between IL and the solvents.

“…Data sources for vapor-phase viscosity were not found. Data from several liquid-phase data sets at atmospheric pressure (Carvalho, Fonseca, Moita, Santos, & Coutinho, 2015;Losetty, Wilfred, & Shekar, 2016;Sun, Niu, Gao, Shen, & Wei, 2015;Zhao et al, 2015) were used to obtain the coefficients in Table 2. Figure 213 shows deviations from experimental viscosity data as a function of temperature, and Figure 214 as a function of pressure.…”

We describe models for the viscosity, thermal conductivity, and surface tension for selected fluids implemented in version 10.0 of the NIST computer program, NIST Standard Reference Database 23, also known as NIST Reference Fluid Thermodynamic and Transport Properties Database (REFPROP). These fluids do not presently have published reference fluid quality models in the open literature, so we provide preliminary models based on available data as an interim measure to allow calculations of these properties. Comparisons with available experimental data are given.

“…Chennuri et al [15] have reported the apparent molar properties and relevant derived properties of the binary mixtures of protic ILs with polar solvents such as water and ethanol at various concentrations and temperatures by employing the Redlich-Mayer type equation. As reported earlier, [16] synthesis and characterization of [C 8 mim][OAc] type IL and experimentally measured the density and viscosity of pure compounds and their binary solutions of IL + DMSO/DMF/EG at various temperatures and concentrations. The derived thermodynamic properties such as volumetric, viscometric properties and their empirical coefficients were calculated from the experimental data.…”

“…The experimental density results were compared with various functionalized ILs with DMF solvent at 303.15 K which were readily available in literature. [4,16,28] From Figure 2, [BDMAH] exhibited lowest density data due to the size, shape and force of attraction between the component molecules. Furthermore, the IL,[C n mim]Cl with DMF intensely showed lower density values then compare to water used as solvent with same IL.…”

This study reveals that the effect of anion structures on solvent‐solute interactions by analysis of sophisticated thermophysical properties of ionic liquids (ILs) with molecular solvent. Three imidazolium based ILs (1‐octyl‐3‐methylimidazolium) [Omim][NTf2], [Omim][PF6] and [Omim][SCN] were synthesized, characterized and measured the thermophysical properties such as density (ρ) sound speed (u) and viscosity (η) of all ILs with DMF as solvent for binary mixture at various conditions. Furthermore, various derived thermophysical propertiesVΦα , κs,Φ, κΦα and ηr, were calculated from experimental data. The type of interactions such as IL‐IL or IL‐solvent or solvent‐solvent are occurred among the component molecules were estimated from the empirical parameters and COSMO−Rs computational study. The obtained results show that the size of anion is governing the volumetric, acoustic and viscometric properties of the studied ILs with DMF.
