The ultrasonic velocity, density and viscosity of pure and binary liquid mixtures of N-N dimethylacetamide and acetone have been measured over the entire range of composition at temperature 313.15 K to evaluate the other thermo dynamical parameters such as adiabatic compressibility, intermolecular free length, free volume, internal pressure, relative association, Rao constant and Wada constant. The variation of these parameters with composition of the mixture was found to be useful in understanding the nature of intramolecular and intermolecular interactions of liquid systems. The non linearity found in all the plots of these thermodynamic parameters with the composition range indicates presence of the intermolecular interaction between the components of the unlike molecules of the mixture.

Abstract


The ultrasonic velocity, density and viscosity of pure and binary liquid mixtures of N-N dimethylacetamide and acetone have been measured over the entire range of composition at temperature 313.15 K to evaluate the other thermo dynamical parameters such as adiabatic compressibility, intermolecular free length, free volume, internal pressure, relative association, Rao constant and Wada constant. The variation of these parameters with composition of the mixture was found to be useful in understanding the nature of intramolecular and intermolecular interactions of liquid systems. The non linearity found in all the plots of these thermodynamic parameters with the composition range indicates presence of the intermolecular interaction between the components of the unlike molecules of the mixture.
