Volumetric and viscometric study and modelling of binary systems of diethyl tartrate and alcohols
Abstract
Density, viscosity, refractive index and speed of sound have been measured for the pure ester diethyl tartrate at atmospheric pressure and over the temperature range from 288.15 K to 323.15 K. Detailed investigation regarding volumetric and viscometric properties was conducted under the same conditions for three binary mixtures: diethyl tartrate +1-propanol or +1-butanol or +1-hexanol. Excess and deviation functions have been calculated from experimental data and correlated with the Redlich-Kister equation. These functions were further discussed in terms of molecular interactions existing in the mixtures as well as the temperature influence on them. Additionally, excess molar Gibbs energies of activation of viscous flow and partial and excess partial molar volumes were determined for investigated systems. Modelling was performed for viscosity and excess molar volume and the obtained results were analyzed taking into account the applied approaches and models.
