An ultrasonic study of acrylates with dodecane-1-ol at 313.15 K

Ultrasonic velocities of binary liquid mixtures of methyl acrylate, ethyl acrylate, butyl acrylate and methyl methacrylate with dodecane-1-ol have been measured at 313.15 K and at atmospheric pressure. Deviations in isentropic compressibility were calculated and have been fitted to Redlich-Kister polynomial equation. Ultrasonic velocities calculated theoretically using Nomoto, Van Dael, free length theory and collision factor theory. Different derived thermodynamic parameters like relative association, molecular association, Rao’s constant (molar sound velocity), excess specific acoustic impendence, excess intermolecular free length, excess available volume and excess intrinsic pressure were also calculated. Graphical representations of these parameters used to explain type and extent of intermolecular interactions in these binary systems
