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

Thermodynamic properties of (an alkylbenzene + cyclohexane) at the temperature 298.15 K

“…The excess molar volumes of the mixtures lie in the sequence: benzene (4) q toluene (10) q ethylbenzene q propylbenzene q 1-methylethylbenzene, which are arranged along with the increase of the molar volume, as found in figure 3. The larger the molar volume is, V T , according to restricted rotation because of a non-smooth sphere contrary to the smooth spherical benzene.…”

Solute–Solvent and Solute–Solute Interactions of Resorcinol in Mixed 1,4-Dioxane–Water Systems at Different Temperatures

“…Sound speeds were determined with an uncertainty of 0.3 % using a single-crystal variable-path ultrasonic interferometer (Mittal Enterprises, New Delhi, India) operating at 4 MHz which was calibrated with water, methanol, and benzene at each temperature, as described in detail elsewhere [18,19]. The experimental values of densities (ρ 0 ) and viscosities (η 0 ) of pure 1,4-dioxane and 1,4-dioxane + water mixtures at 303, 313, and 323 K are reported in Table I.…”

Thermodynamic properties of (1,3 -dioxane, or 1,4-dioxane + a non-polar liquid) atT= 298.15 K; speed of sound, excess isentropic and isothermal compressibilities and excess isochoric heat capacity

“…(2)(3)(4) The speed of sound u was measured by the sing-around method (Cho-onpa, SVM-2). The cell used in the measurement of the speed of sound was immersed in a water bath controlled at T = (298.15 ± 3 · 10 −4 ) K. (5) The delay time of the apparatus was calibrated before and after every series of measurements of the speed of sound in water (6) and a slow drift in delay time was averaged in the time interval of the measurements. The precision was better than 0.05 m · s −1 .…”
