Abstract

Densities and Ultrasonic velocities of the binary liquid mixtures of Anisicaldehyde with Methyl Acetate (MA) Ethyl Acetate (EA) and Butyl Acetate (BA) have been measured at a temperature range from 303.15 to 318.15 K with an interval of 5 K, over the entire composition of mole fractions. The theoretical values of ultrasonic velocity were evaluated using the Nomoto’s relation (UNR), Impedance relation (UIR), Ideal mixing relation (UIMR), Rao’s specific velocity relation (UR) Junjie’s relation (UJR) and Danusso model (UD). The molecular interaction parameter (χ), Chi-square value, average percentage error (APE) have been evaluated to find the best applicable theory. The variation of this interaction parameter with the mole fraction of common compound has been discussed in terms of molecular interactions.
