Theoretical Evaluation of Ultrasonic Velocity in Binary Mixtures of Alcohols with Anisic Aldehyde

Theoretical values of ultrasonic velocity in binary liquid mixtures of anisic aldehyde + pentanol, anisic aldehyde + hexanol and anisic aldehyde+ heptanol have been evaluated at 303.15,308.15,313.15 and 318.15K using Nomoto’s relation, ideal mixing relation (IMR) impedance dependence relation (IDR), Rao’s velocity method (RVM) Junjie’s method (JM) and Danusso method (DM). The relative merits of these theoretical relations were examined by comparing the theoretical values of ultrasonic velocity with the values obtained experimentally. The validity of the theories was checked by applying the chi-square test for goodness of fit and by calculating the average percentage error (APE).
