Speeds of sound, isentropic and isothermal compressibilities, and isochoric heat capacities of {xc-C6H12+(1−x)C6H6}, x{CCl4+(1−x)C6H6}, and x{C7H16+(1−x)C6H6} at 298.15 K

Isobaric molar heat capacities at 288.15, 298.15, and 308.15 K and densities and speeds of sound at 288.15, 293.15, 298.15, and 308.15 K were determined for the dimethyl carbonate + benzene system over the whole composition range and at atmospheric pressure. In addition, speeds of sound at the same temperatures for the dimethyl carbonate + n-heptane system are reported. These experimental data were used to obtain molar volumes, isobaric thermal expansivities, isentropic and isothermal compressibilities, and isochoric molar heat capacities. Excess quantities of the above-mentioned properties were calculated using the Benson and Kiyohara criterion. The thermodynamic behaviour of the dimethyl carbonate + (n-heptane, cyclohexane, benzene, or toluene) systems is comparatively analyzed.Key words: binary mixtures, excess properties, dimethyl carbonate, benzene, hydrocarbon.

Ultrasonic velocities and volumetric heat capacities at constant pressure were measured at 298.15 K for water + tetrahydrofuran mixtures over the whole concentration range using pulse–echo–overlap equipment and a flow microcalorimeter respectively. Isentropic and isothermal compressibilities and heat capacities at constant pressure and at constant volume were derived from the results in combination with the results of previous studies of thermal expansivities and excess volumes. The significance of the excess compressibilities and excess heat capacities is discussed in terms of molecular interactions.
