چکیده انگلیسی
The densities (Ï), ultrasonic speeds (ν), and refractive indices (n) of binary mixtures of styrene (STY) with m-, o-, or p-xylene, including those of their pure liquids, were measured over the entire composition range at the temperatures 298.15, 303.15, 308.15, and 313.15 K. The excess volumes (VE), deviations in isentropic compressibilities (Îks), acoustic impedances (ÎZ), and refractive indices (În) were calculated from the experimental data. Partial molar volumes (V0Ï,2) and partial molar isentropic compressibilities (K0Ï,2) of xylenes in styrene have also been calculated. The derived functions, namely, VE, Îks, ÎZ, În, V0Ï,2, and K0Ï,2 were used to have a better understanding of the intermolecular interactions occurring between the component molecules of the present liquid mixtures. The variations of these parameters suggest that the interactions between styrene and o-, m-, or p-xylene molecules follow the sequences: p-xylene>o-xylene>m-xylene. Apart from using density data for the calculation of VE, excess molar volumes were also estimated using refractive index data. Furthermore, several refractive index mixing rules have been used to estimate the refractive indices of the studied liquid mixtures theoretically. Overall, the computed and measured data were interpreted in terms of interactions between the mixing components.
