Computational studies of molecular interactions in the binary mixtures of ethyl lactate and nitro-, chloro- and bromo-benzenes

Associations between the molecules in the binary mixtures of ethyl lactate and certain substituted benzenes are presented in this study from the measurements of density and viscosity. The densities and viscosities for pure liquids and their binary mixtures have been measured in the temperature range 303.15-318.15 K. The excess parameters such as excess molar volumes, excess viscosity are computed from the experimental data. The excess molar volumes are found to be negative whereas the deviations in viscosity are found to be positive for all the mixtures. An attempt is made to compare the merits of the theoretically evaluated viscosities using various models with the experimental values. (C) 2019 Elsevier Ltd. All rights reserved.
