摘要：Ultrasonic velocity , viscosity and density,of binary mixtures of N,N-dimethyl Acetamide with (NNDA) withDiethyl Amine (DEA)at 303.15K, 308.15K, 313.15K and 318.15K over the entire composition range of NNDA at a fixedfrequency of 10MHz using Ultrasonic Interferometer was measured. Experimental data have been used to calculate excessthermodynamic parameters such as excess molar volume (VmE), excess ultrasonic velocities (UE), excess acoustic impedance(ZE), excess adiabatic compressibility (βadE), excess in viscosity (ηE), excess free length (LfE) and excess Gibbs free energy ofactivation of viscous flow (ΔGE).The values of βadE and LfE exhibits positive deviations and ηE exhibits negativedeviationover the wide range of composition for all the binary mixture which suggest that dispersive forces are operative inthe system in addition to dipole-dipole, dipole induced dipole interactions.The excess/deviations were fitted by a Redlich-Kister equation and the results were analysed in terms of specific interactions present in the mixture.
