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 knowledge of acoustical properties of pure liquid and liquid mixtures furnishes information on molecular structure, nature, and strength of molecular interactions. The physical and chemical properties of solutions and biomolecules have been studied by many workers [1][2][3][4] and evaluated thermodynamic and other related parameters with structural changes occurring in solutions with respect to variation in concentrations and temperatures. N,N-dimethylformamide (DMF) is a versatile solvent, used in the synthesis of pharmaceuticals, in agriculture chemistry, and serves as solvent for many polymers.…”

Density (q), viscosity (g) and ultrasonic velocity (u) of 5-chloro-2-hydroxy-3-nitroacetophenone (CHNA) in N,N-dimethylformamide have been measured at 298.15, 303.15, 308.15 and 313.15 K. From these experimental data, various thermodynamic and ultrasonic parameters such as specific acoustic impedance (Z), adiabatic compressibility (b s ), intermolecular free length (L f ), relative association (R A ), relaxation strength (r), free volume (V f ), internal pressure (P i ), solvation number (S n ), apparent molar volume (V / ), apparent molar adiabatic compressibility (K s,/ ) with their limiting values and slopes have been evaluated. The viscosity data have been analyzed in the light of Jones-Dole equation. The variations of these parameters with concentration and temperatures have been studied and results have been interpreted in the light of various interactions occurring in solution under applied experimental conditions.

“…Measurement of ultrasonic velocity [8][9][10][11] has been adequately employed in understanding the molecular interactions in pure, binary, and higher order multicomponent liquid mixtures. The propagation of ultrasonic velocity in a medium is a thermodynamic property and has come to be recognized as a very specific and unique tool for predicting and estimating various physio-chemical properties of the systems under consideration [12] .…”
