Densities, Viscosities, and Refractive Indices, of Binary Mixture of Ethyl Benzoate with Ethyl Acetate from 293.15 K to 313.15 K

Abstract

In the present paper, thermochemical properties such densities, ρ, viscosities, η, and refractive indices, n_D, of binary mixture of  ethyl benzoate (EB) with ethyl acetate (EA) over the whole composition range at temperatures between 293.15 and 313.15 K under atmospheric pressure have been measured. Based on the measurements, excess molar volume, V^E, viscosity deviations, Δη, excess Gibbs energies of activation of viscous flow, ΔG^*E, and deviation in refractive indices, Δn_D were calculated then fitted to the Redlich–Kister polynomial equation to obtain the coefficients. The experimental results for the binary mixture at 298.15 K and the pure components at different temperatures were comparable to those found in previous research. The properties were explained in terms of the predominant molecular interactions in the mixtures.
