Theoretical Ultrasonic Velocities in Binary Liquid Mixture Containing Aniline and Anisole at Different Temperatures – A Comparative Study

Abstract

Ultrasonic velocity is measured experimentally at 3MHz frequency in the binary liquid mixture containing aniline and anisole at different temperatures over the entire composition range and theoretical values of ultrasonic velocity have been evaluated by using Nomoto's relation, Impedance relation, Van Dael ideal mixture relation. These theoretical values are compared with the experimental values. A good agreement has been found between experimental and theoretical ultrasonic velocities.

Study of Acoustical Parameters in Binary Liquid Mixture Containing 1-Butanol and Hexane at Temperatures 313.15 K, 318.15 K and 323.15 K

“…The values of adiabatic compressibility () can be calculated by the following relation: where u is ultrasonic velocity and p is density. The experimentally measured values of pure components are compared with the literature [9][10][11][12][14][15][16][17] values and are given in (Table 1). …”

Study of Acoustical Parameters in Binary Liquid Mixture Containing 1-Butanol and Hexane at Temperatures 313.15 K, 318.15 K and 323.15 K

“…where u is ultrasonic velocity and p is density. The experimentally measured values of pure components are compared with the literature [9][10][11][12][14][15][16][17] values and are given in (Table 1). 2 it is observed that the ultrasonic velocity increases with increase in mole fraction of 1-butanol.…”

Studies of Densities, Viscosities and Ultrasonic Speeds of Binary Mixtures Containing Isopropyl Alcohol and Ketones at Different Temperatures

“…The intermolecular free length decreases with decrease of temperature and hence the close packing of molecules which in effect decreases the sound velocity [5,6]. The compressibility decreases with increase of velocity that gives insight into the structure making and structure breaking of components in binary mixtures [7,[18][19][20]. In this work we report the experimental values of the density, viscosity and ultrasonic velocity of the above binary mixtures at the temperatures 298.15 and 308.15 K. These data have been used to calculate various acoustical parameters like adiabatic compressibility (β), free volume (V f ) and free length (L f ).…”
