“…Generally, examination of the trends of the dependence of excess properties on molar composition in binary mixtures (curves with extrema around the middle of composition range) [1][2][3][4][5][6][7][8] , suggested that many of these systems are similar. So, the excess quantity gives an overall view of the origin of the non-ideality in the mixtures but still can be quite misleading.…”

“…In the present study the excess molar properties and viscosity deviations [1][2][3][4][5][6][7][8] are fitted to the reduced Redlich-Kister (R-K) equation along with its corresponding relative properties and the Herráez 17,18 and Belda correlative equations [19][20][21] . In addition, the reduced R-K function relative to the viscosity Arrhenius activation energy which is equivalent to the apparent molar property gives more information because it is more sensitive than the excess property to interaction 22,23 .…”

Values of excess properties in 1,2-dimethoxyethane + propylene carbonate binary liquid mixtures at different temperatures from experimental density and viscosity values presented in earlier work, were used to test the applicability of the correlative reduced Redlich-Kister functions and the Belda equation, and to reveal eventual specific interaction hidden by the classical treatment of direct excess Redlich-Kister functions. Their correlation ability at different temperatures, and the use of different numbers of parameters, is discussed for the case of limited experimental data. The relative Redlich-Kister functions are important to reduce the effect of temperature and, consequently, to reveal the effects of different types of interactions. Values of limiting excess partial molar volume at infinite dilution deduced from different methods were discussed. Also, the activation parameters and partial molar Gibbs free energy of activation of viscous flow against compositions were investigated. Correlation between the two Arrhenius parameters of viscosity shows the existence of main different behaviors separated by a stabilized structure in a short range of mole fraction in 1,2-dimethoxyethane (0.45 to 0.83). In this context, the correlation Belda equation has also been applied to the present system for thermodynamic properties in order to reveal eventual solute-solvent interaction at high dilution.

“…Densities of pure liquids and liquid mixtures were measured by relative density method [15-18] using 10 mL relative density bottle and weighed with an accuracy of ± 0.001 kg m -3 . Viscosities were determined using an Oswald viscometer of 10 mL capacity with an accuracy of ± 0.001 mPa [15][16][17][18][19]. From the measured values of density (ρ) and flow time (t), viscosity (η) was calculated using the following relation [14][15][16][17]: [ ] [ ]…”

Densities, viscosities and ultrasonic velocities of binary liquid mixtures of methyl benzoate with chlorobenzene and benzaldehyde have been measured at 308.15K and 318.15 K. By these experimental data excess volume (V E ), deviation in isentropic compressibility(∆KS), deviation in viscosity (∆η) intermolecular free length (∆Lf), intermolecular free volume (∆Vf) and deviation in acoustic impedance(∆Z) were calculated. These results have been correlated with the Redlich and Kister type polynomial equation to derive the coefficients and standard errors. Significance of the calculated excess quantities were analyzed for mixtures of methyl benzoate with chlorobenzene and benzaldehyde, through which intermolecular interactions have been investigated.

“…Our experimental values of densities, viscosities and ultrasonic velocities match very well with those reported in the literature and are presented in Table-1. Binary liquid mixtures of different compositions were prepared by mixing fixed quantity of pure liquids in air tight stoppered bottles of 50 mL capacity. Densities of pure liquids and liquid mixtures were measured by specific gravity method [10][11][12] with 10 mL relative density bottle and weighed with an exactness of ± 0.001 kg m -3 . Viscosities were determined by Oswald viscometer 10 mL capability with an accurateness of ± 0.001 cP [10][11][12].…”

Densities, viscosities and ultrasonic velocities of binary liquid mixtures of diethyl malonate with aniline and benzaldehyde have been measured at 308.15 and 318.15 K. From these data, excess volume (V E ), deviation in isentropic compressibility (∆KS), deviation in viscosity (∆η), deviation in intermolecular free length (∆Lf), deviation in free volume (∆Vf), deviation in internal pressure (∆πi) and deviation in acoustic impedance (∆Z) have been calculated. These results were correlated with the Redlich and Kister type polynomial equation to derive the coefficients and standard errors. Variations in the calculated excess quantities have been studied for mixtures of diethyl malonate with component liquids. From the value of excess properties, intermolecular interactions have been studied.
