The densities and speed of sound for liquid mixtures containing vitamin B 3 (niacin) at 0.01, 0.03, and 0.05 mol·kg –1 concentrations in aqueous propylene glycol and hexylene glycol at the variation of temperatures from 293.15 to 308.15 K have been measured using an Anton Paar DSA 5000 M. From volumetric experimental data, apparent molar volume ( V ϕ ), partial molar volume ( V ϕ 0 ), and partial molar volume of transfer (Δ V ϕ 0 ) are calculated along with the apparent molar isentropic compression ( K ϕ, S ), partial molar isentropic compression ( K ϕ, S 0 ), and partial molar isentropic compression of transfer (Δ K ϕ 0 ) using experimental acoustic data. The positive volumetric data (i.e., apparent molar volume and partial molar volume) indicates strong solute–solvent interactions inside the mixture. Along with these values, the empirical constants a , b , and c with the pair and triplet coefficients ( V AB , V ABB , K AB , K ABB ) are also calculated.

“…In the present study, the values of Δη (Table 4) are varying with the structural characteristics of the liquid components, which may be due to the geometrical fitting of one component into the empty space of the other component due to the differences in molecular size and shape of the components. As the concentration of 2-chloroaniline increases the [42][43][44]. The positive values indicate the strong interaction between the molecules and negative values indicate the dispersion forces between the molecules.…”

At multiple temperatures, 288.15–318.15 K, the density and speed of sound values for PEGs of molecular weights 400 and 4000 in aqueous niacin solutions were measured at concentrations of 0.07, 0.08, and 0.09 mol·kg–1. Utilizing these experimental data, the apparent molar properties and partial molar properties were determined to analyze the interactions in aqueous niacin solutions with poly(ethylene glycol)s (400/4000). The volumetric parameters, such as apparent molar volume, V ϕ, partial molar volume, V ϕ 0, and partial molar volume of transfer, ΔV ϕ 0, are obtained using experimental density values, while the acoustic parameters, i.e., apparent molar isentropic compression, K ϕ,S, partial molar isentropic compression, K ϕ,S 0, and partial molar isentropic compression of transfer, ΔK ϕ,S 0, are determined with the speed of sound data. These positive volumetric apparent and partial molar properties suggest the presence of strong solute–solvent interactions. The partial molar expansibilities (E ϕ 0) along with their first derivative (∂E ϕ 0/∂T)P were calculated. Further, pair and triplet coefficients are obtained using partial molar isentropic compression and partial molar volume of the transfer, respectively.
