The ultrasonic velocity, density and viscosity have been measured for the ternary mixtures N, NDimethylacetamide and N-Methylacetamide with Alkoxyethanols in Carbon tetrachloride at 303, 313 and 323K. The experimental data have been used to calculate the acoustical parameters namely adiabatic compressibility (β), free length (Lf), free volume (Vf) and internal pressure (πi),. From the obtained values, molecular interactions have been found through hydrogen bonding between solute and solvent liquid mixtures.
