Abstract

The density and viscosity (T=303.15K) in the binary mixtures of 2-ethoxyethanol and chlorobenzene has been measured as a function of composition. Excess volumes were measured by using relative density method and the viscosity of pure liquids and liquid mixtures were determined using an Oswald’s viscometer. Theseresults have been fitted to the Redlich and Kister type polynomial equation to estimate the interaction parameter and standard deviation. Excess volumes exhibited both positive and negative trends in binary mixtures, depending upon the nature of the second component of the mixture. For the binary mixture calculated thermodynamic quantities have been discussed in terms of intermolecular interaction between mixing components.
