Density, ρ, viscosity, η, speed of sound, u, and refractive index, nD, were measured for the binary systems of ethyl acetoacetate with dichloromethane, chloroform, carbon tetrachloride, nitromethane, methyl acetate, acetonitrile and acetic acid at 298.15 K over the entire composition range. From the experimental results, the excess molar volume, V E and the deviation in viscosity, ∆η, were calculated. Isentropic compressibility, kS E , and deviation in molar refractive index, ∆R, were also calculated. These results were fitted to Redlich-Kister polynomial equation. The density and viscosity data were analyzed by some semi-empirical viscosity models, and the results have been discussed in terms of molecular interactions and structural effects. The excess properties were found to be either negative or positive depending on the molecular interactions and the nature of liquid mixtures. To explore the nature of the interactions, various thermodynamic parameters (e.g., intermolecular free length, specific acoustic impedance, etc.) have also been derived from the density and ultrasonic speed data.

“…For mixing properties, the estimated uncertainties are 6•10 -8 m 3 mol -1 for excess molar volume, 0.46 % for viscosity deviation, 8.6•10 −4 for refractive index deviation and 0.96•10 −12 Pa -1 for excess isentropic compressibility.

The aim of this research is the experimental determination of density, viscosity, refractive index and speed of sound for binary mixtures of the ester ethyl acetate and alcohols. Experimental measurements were carried out for two systems with 1-propanol and 1-butanol at atmospheric pressure and in a temperature range 288.15 - 323.15 K. Results of experimental measurements were further used to determine excess molar volumes, viscosity deviations, refractive index deviations, and excess isentropic compressibility for each investigated mixture. These calculated data were correlated using the empirical Redlich-Kister equation. Positive values of the excess molar volume and isentropic compressibility appear for both analysed systems, while values of viscosity and refractive index deviations are negative. The structure and specific characteristics of different molecules in considered mixtures and determined non-ideal behaviour allow the insight into the possible type of interactions in the mixture, interstitial accommodation and structural effects.

“…The mass fraction purities as determined by gas chromatography (HP 8610) using FID were as follows: methyl benzoate (>0.996), tetrahydrofuran, (>0.996), 1,4-dioxane, (>0.998), anisole, (>0.998), and butyl vinyl ether (>0.997). The purity of the samples was further checked by comparing the measured density and viscosity with the literature values [18][19][20][21][22][23][24][25][26][27][28] as shown in Table 1. .…”

“…Several authors have also published density, viscosity, and speed of sound data [14][15][16][17][18][19][20] of binary mixtures of methyl benzoate with different types of organic solvents. In the present study, we report the results of density , viscosity , and speed of sound for the binary mixtures of methyl benzoate with ethers, namely, tetrahydrofuran, 1,4-dioxane, To the best of our knowledge, such data on the abovementioned mixtures are not available in the earlier literature.…”

Densities, viscosities, and speed of sound have been determined at T = (303.15, 308.15, and 313.15) K for the binary mixtures of methyl benzoate with tetrahydrofuran, 1,4-dioxane, anisole, and butyl vinyl ether over the entire range of composition. Using these measured values, excess volume , deviation in viscosities Δ , excess Gibb's free energy of activation for viscous flow Δ * , and deviation in isentropic compressibility Δ have been calculated. These calculated binary data have been fitted to Redlich-Kister equation to determine the appropriate coefficients. The values of excess volume and deviation in viscosities Δ are negative over the entire range of composition for all the binary systems at the studied temperatures. The behavior of these parameters with composition of the mixture has been discussed in terms of molecular interactions between the components of liquids.
