Experimental and Theoretical Studies of Ultrasonic Velocityin Binary Liquid Mixtures of Ethyl benzoate

Abstract

Ultrasonic velocity is measured at 2MHz frequency in the binary mixtures of Ethyl Benzoate with 1-Propanol, 1-Butanol, 1-Pentanol and theoretical values of ultrasonic velocity have been evaluated at 303K using Nomoto's relation, Impedance relation, Ideal mixture relation, Junjie's method and free length theory. Theoretical values are compared with the experimental values and the validity of the theories is checked by applying the chi-square test for goodness of fit and by calculating the average percentage error (APE). A good agreement has been found between experimental and Nomoto’s ultrasonic velocity.

Experimental and Theoretical Studies of Ultrasonic Velocity in Ternary Liquid Mixtures of Methyl Benzoate, Cyclohexane and Alcohols at Different Temperatures

“…This is probably due to the fact that the thermal energy activates the molecule, which would increase the rate of association of unlike molecules 19 . Similar kinds of results were obtained by earlier workers [20][21][22][23][24][25] . The ratio U exp 2 /U IMR 2 is used to measure the non-ideality in It is observed from the Tables 1, 3, 5 and 7 that Nomoto's relation predicts a good agreement of sound velocity with the experimental values in ternary mixtures all the systems.…”

Acoustic Properties of Binary Liquid Mixtures Containing N-Methyl Formamide With Anilines at Different Temperatures

“…1,2 Previously many researchers have worked in this field by measuring the density, viscosity, and speed of sound for a wide range of liquids and their binary as well as ternary mixtures. [3][4][5][6][7][8][9] The compounds used here are of great importance for their relevant role in chemistry, biology in liquid mixtures. The study of thermodynamic properties of liquid mixtures containing many components and having data for analysis in terms of various models are of great significance for industrial and pharmaceutical applications.…”
