Experimental high-temperature, high-pressure (HTHP) density of three solvents including dimethyl sulfoxide, benzyl alcohol, and isoamyl acetate was measured at temperatures of 293.15–473.15 K and pressures up to 35–37.5 MPa. The density was measured with an Anton Paar density meter (DMA HP) at 20 K and 2.5 MPa intervals. The calibration fluids were water and benzene. The combined expanded uncertainty of density taking into account the device specification and the impurities of the materials was 1 kg·m–3 (0.95 level of confidence). The experimental density data were correlated with the Tait and new modified Tait equations. The thermal expansion coefficient (α p ) and isothermal compressibility (κ T ) were calculated with the new modified Tait equations. Moreover, the perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state was used to model the density data at HTHP. In most cases, the PC-SAFT parameters are obtained from saturated vapor pressure and liquid phase density; however, these parameters were calculated from the density at HTHP in the present study. Regarding these parameters, thermodynamic properties such as the thermal expansion coefficient (α p ), isothermal compressibility (κ T ), isobaric heat capacity (C P ), and speed of sound (u) were calculated. Acceptable agreement between the results with experimental data demonstrated the accuracy of modeling with the obtained parameters.

“…The experimental values of density (ρ), viscosity (η), and ultrasonic velocity ( U ) of the pure solvent are given in Table along with literature values. − Table shows the experimental density, ultrasonic velocity, and viscosity data for the studied compounds at different temperatures along with their standard uncertainties (in the table footnote). It is evident from Table that all three experimentally measured properties increase with increasing molality of the compound at all three studied temperatures.…”

Some novel dihydropyridine derivatives, viz., 4-(4-hydroxy- and 4-(4-hydroxy-3-methoxyphenyl)-2-oxo-6-phenyl-1,2-dihydropyridine-3-carbonitrile have been synthesized, and characterization of these synthesized compounds has been done by IR, 1 H NMR, 13 C NMR, and mass analyses. The densities (ρ), viscosities (η), and ultrasonic velocities (U) of these dihydropyridine derivatives have been measured in dimethyl sulfoxide at different temperatures over a wide range of molalities. From these experimental data for ρ, η, and U, various acoustical parameters and some apparent molar parameters have been calculated. The obtained results are interpreted in terms of solute−solvent and solute−solute interactions, giving an idea of the structure-making or structure-breaking abilities of the studied compounds in dimethyl sulfoxide solution.

“…Ionic liquids (ILs) are a new class of chemical compounds with low melting points, mainly below 373.15 K. They have distinctive properties, such as negligible vapor pressure, wide liquid temperature range, good solvation capacity for organic and inorganic substances, and potential recoverability. 1,2 Especially, as solvents, they have been used in many fields, for example, extraction and electrochemical solvents. 3,4 However, the highly viscous behavior of pure Ils has been considered to be a main limiting factor for their large-scale applications.…”

The binary mixtures composed of 1-ethyl-3-(2methoxyethyl)-imidazolium bis(trifluoromethylsulfonyl)imide [C 2 2O1IM][NTF 2 ] and alcohols were prepared, and the density and viscosity were measured first across the entire range of mole fraction within a particular temperature range. Based on the experimental values of density, the average molar volume, the excess molar volume, and the partial molar volume were calculated, and the excess molar volume was well fitted by Redlich−Kister equation. In addition, in order to describe the excess activation Gibbs energy of viscous flow simply and directly, the relative volume of mixtures, V r , is introduced in this paper and then combined with the relative viscosity, η r , and a new find about the nondimensional Gibbs energy of activation for viscous flow of the mixture, ΔG ⧧E /RT, could be obtained.
