“…For the mixture of liquids (water + d-Panthenol + PEG 600/PEG 6000), the values of speed of sound are retrieved at temperatures 288.15, 298.15, 308.15, and 318.15 K and 0.01 MPa pressure as the function of d -Panthenol concentrations (0.00, 0.02, 0.07, and 0.12 mol kg –1 ). These experimental speed of sound values are indexed in Table and are compared with the literature values for the binary mixture of water + PEG 600/PEG 6000 , in Figure and for the binary mixture of water + d -Panthenol in Figure b. The experimental speed of sound results are in agreement with the published velocity values for different temperatures.…”

“…This trend of the experimental values is in accordance with the literature. Further, as the concentration of d -Panthenol increases, the values of density increase, and as the molecular mass of the poly(ethylene glycol) becomes higher, i.e., from PEG 600 to PEG 6000, an increase in the density is observed, which is caused by the increment in the chain length of the solute. − …”

The present study involves measurement of the density and ultrasonic speed of sound via Anton Paar DSA 5000 M for the binary mixture of water + poly(ethylene glycol) 600/poly(ethylene glycol) 6000 and ternary mixture of water + d-Panthenol + poly(ethylene glycol) 600/poly(ethylene glycol) 6000 covering a whole range of compositions (0.00, 0.02, 0.07, and 0.12 mol kg–1) at 0.01 MPa pressure from 288.15 to 318.15 K. The volumetric properties (apparent molar volume, partial molar volume, and partial molar volume of transfer) are evaluated from the density data; meanwhile, the speed of sound data is utilized to determine the acoustic properties (apparent molar isentropic compression, partial molar isentropic compression, and partial molar isentropic compression of transfer). This investigation is further extended by calculating the partial molar expansibility with its first derivative and pair-triplet interaction coefficients from these derived thermodynamic parameters. The obtained results from these calculated parameters are expressed as solute–solvent, ion–hydrophilic, hydrophilic–hydrophilic, and dipole–dipole interactions prevailing in the liquid sample.

At the variation of temperatures from (293.15 to 308.15) K, the densities and speed of sound for liquid mixtures containing propylene glycol and hexylene glycol in aqueous vitamin B3 (niacin) at (0.01, 0.03, and 0.05) mol·kg-1 concentration has been measured with Anton Paar DSA 5000 M. These experimental data were used to calculate various acoustic and thermodynamic parameters such as intermolecular free length, acoustic impedance, adiabatic compressibility, Wada’s constant, Rao’s Constant and Vander Waal’s constant which gave the insight of the intermolecular reactions inside the ternary mixture of vitamin B3(Niacin) and glycols (PG/HG).

“…Chakraborty et al obtained the acoustic and volumetric properties of d -panthenol in an aqueous medium of PEGs at different temperatures. These estimated parameters are used to characterize the results in terms of (solute–solute) and (solute–solvent) interactions, including the ability of PEGs to form and break structures in a d -panthenol aqueous solution.…”

The density and sound velocity values for polyethylene glycols (PEGs) with molecular weights 200 and 400 in ethanol–chlorhexidine solutions were investigated at different temperatures, 288.15 to 318.15 K, and concentrations of 0.001, 0.003, and 0.005 mol·kg–1. The apparent molar properties and partial molar properties of ethanol–chlorhexidine solutions containing PEGs (200/400) were obtained using this experimental data. The thermodynamic parameters, such as apparent molar volume, (V ϕ), and limiting partial molar volume, (V ϕ 0), are determined using density values obtained experimentally, whereas acoustic properties, such as apparent molar isentropic compression, (K ϕ, s), and limiting partial molar isentropic compression, (K ϕ, s 0), are calculated using sound velocity values. These thermodynamic apparent and partial molar properties imply the occurrence of strong solute–solvent interactions. The temperature-dependent partial molar volume and partial molar expansibilities (E ϕ 0) were also calculated. The presence of strong solute–solvent interactions has been discovered in the liquid mixtures.
