Excess molar volumes, excess thermal expansion coefficients and isentropic compressibility deviations for binary mixtures of benzyl alcohol + (1-butanol, 2-butanol, 2-methyl-1-butanol and <i>tert</i>-butanol) at <i>T</i> = (298.15-328.15) K and ambient pressure

<p>In the present paper, we report the density (<i>ρ</i>) and ultrasonic speed (<i>u</i>) of four binary mixtures of benzyl alcohol with 1-butanol, 2-butanol, 2-methyl-1-butanol and <i>tert</i>-butanol over the temperature range 298.15–328.15 K and ambient pressure, covering the entire composition range, expressed by the mole fraction (<i>x</i><sub>1</sub>) of benzyl alcohol. The experimental data on density and ultrasonic speed were used to calculate the excess molar volumes, , deviations in isentropic compressibility, , excess thermal expansion coefficients, , excess partial molar volumes, , and excess partial molar volumes at infinite dilution, . The results obtained were used to investigate the nature and strength of intermolecular interactions in these mixtures. The calculated quantities , and are well correlated with the Redlich–Kister equation.</p>
