%X The density, viscosity and ultrasonic velocity of ternary liquid mixtures of N,Ndimethylformamide,cyclohexane and benzene have been measured at different frequencies (2MHz,4MHz and 6MHz) using a multi frequency ultrasonic interferometer over the entire range of molefraction at temperature 318 K. The data have been utilized to compute the acoustical parameterssuch as adiabatic compressibility (¦Â), free length (Lf), free volume (Vf), internal pressure (§±i),relaxation time (¦Ó), acoustic impedance (Z), and Gibb¡¯s free energy (¦¤G) and their excess values,using the standard relations. The variations of sound speed with frequency plays a key role inanalyzing the intermolecular interactions present in the ternary mixture. The results have beeninterpreted in terms of molecular interactions existing between the components of the mixtures.
