|Abstract:||Various acoustical parameters such as adiabatic compressibility (), free length (Lf), free volume (Vf), internal pressure (i), excess adiabatic compressibility (E), excess free length (LfE), excess free volume (VfE), excess internal pressure (iE), excess viscosity (E) and excess velocity (UE) have been evaluated from density, viscosity and speeds of sound measurements for solvent systems consisting of methyl acetate and toluene with 1-pentanol, 1-hexanol and 1-heptanol at 303.15, 308.15 and 313.15 K. These excess properties have been used to discuss the presence of significant interactions between the component molecules in the ternary mixtures. The ultrasonic speeds calculated according to Nomoto’s relation, impedance dependence relation and collision factor theory are compared with those obtained experimentally.|
