Abstract

MOLECULAR INTERACTION IN TERNARY LIQUID MIXTURES AT DIFFERENT TEMPERATURES

Manoj Kumar Praharaj* and Sarmistha Misra

ABSTRACT

Ultrasonic velocity, density and viscosity have been studied in ternary liquid mixture containing N,N-dimethylformamide, Cyclohexane and Toluene at different temperatures 288K, 298K, 308K and 318K over the entire composition range. From these experimental values various parameters like adiabatic compressibility, free length, free volume, internal pressure, acoustic impedance etc and their excess values have been evaluated. The different parameters and their excess values were ploted against the mole fraction of N,N-Dimethylformamide over the whole composition range. The parameters and the observed values of excess parameters were explained on the basis of intermolecular interaction present in the above mixture.

Keywords: Toluene, ultrasonic velocity, excess adiabatic compressibility, excess Gibbs' parameter.
