“…The values of H E at atmospheric pressure are also shown in the graphs for comparison. As reported by Lien et al, 2 the maximum H E values of the corresponding systems at atmospheric pressure are 641.8 J‚mol -1 , 670.7 J‚mol -1 , 674.0 J‚mol -1 , 650.3 J‚mol -1 , and 386.6 J‚mol -1 , respectively. This reveals that the excess enthalpies decrease with increasing pressure in the mixtures of DMC + o-xylene, + m-xylene, + p-xylene, and + ethyl benzoate but increase slightly with increasing pressure in the mixtures of DMC + ethylbenzene.…”

“…1 It is also widely used as a solvent in many liquid extraction processes. Lien et al 2 measured the heats of mixing for the binary systems of DMC with o-xylene, p-xylene, m-xylene, ethylbenzene, or ethyl benzoate at 298.15 K under atmospheric pressure. As an extension, similar measurements were made in this work at 10.2 MPa for the same five binary systems to reveal the pressure effect on H E .…”

A flow-type isothermal microcalorimeter was used to measure excess molar enthalpies, H E, for the binary mixtures of dimethyl carbonate with o-xylene, m-xylene, p-xylene, ethylbenzene, or ethyl benzoate at 298.15 K and 10.2 MPa. The experimental H E values are positive for all the binary mixtures over the entire composition range. In comparison with the values of H E at 0.1 MPa, the excess enthalpies were found to decrease with increasing pressure for these binary systems, except for dimethyl carbonate + ethylbenzene. The maximum H E values are in the range 356.8 J·mol-1 to 652.8 J·mol-1, which are located at about x i = 0.5. The experimental H E data were correlated accurately with the Redlich−Kister polynomial equation. The Peng−Robinson and the Cubic Chain-of-Rotators equations of state with the binary interaction parameters determined from H E data at atmospheric pressure were adopted to calculate the excess enthalpies at 10.2 MPa. The Cubic Chain-of-Rotators equation with two binary interaction parameters yielded better results.

“…Physical properties of several esters in their binary mixtures have been already reported [1][2][3][4][5][6][7][8]. However, studies in this regard for the determination of refractive indices of the binary mixtures of n-butylethanoate and 3-methylbutylethanoate at 308.15K are still lacking.…”

Refractive indices have been measured for the binary liquid mixtures of n-butylethanoate and 3methylethanoate with cyclohexane, benzene, 1,4-dimethylbenzene and 1,3,5-trimethylbenzene over the entire composition range at 308.15K. From the experimental data, the values of deviation in refractive index (n), molar refraction (R) and deviation in molar refraction (R) have been determined. The values of n and R have been fitted to the Redlich-Kister polynomial equation to determine the standard deviation.

“…Blanco et al [2] studied the excess properties (V E , η and G * E ) of binary mixtures of alkyl benzoates with n-heptane at four temperatures between 288.15 and 318.15 K, while Grolier et al [3] and Dusart et al [4] have determined V E values for binary mixtures (methyl benzoate or ethyl benzoate + n-heptane) at 298.15 K. Likewise, a literature search has shown that excess properties of binary mixtures containing ethyl benzoate have previously been studied by several authors [5][6][7][8][9][10][11][12]. However none of these papers report the acoustic properties of the binary mixtures.…”

Densities, viscosities and speeds of sound of binary mixtures of ethyl benzoate with cyclohexane, n-hexane, heptane and octane have been measured over the entire range of composition at (303.15, 308.15 and 313.15) K and at atmospheric pressure. From these experimental values, excess molar volume (V E ), deviation in viscosity ( η) and deviation in isentropic compressibility ( K s ) have been calculated. The viscosities of binary mixtures were calculated theoretically from the pure component data by using various empirical and semi-empirical relations and the results compared with the experimental findings.
