Theoretical Evaluation of Ultrasonic Velocity in Binary Liquid Mixtures of Alcohols [S] + Benzene

Abstract

Ultrasonic velocities and densities of the binary liquid mixtures of benzene with 1-propanol, 2-propanol, 1-butanol, 2-butanol and 3-butanol at 303.15 to 318.15 K, over the entire composition range were measured. The theoretical values of ultrasonic velocity were evaluated using the Nomoto's Relation (NR), Ideal Mixture Relation (IMR), Free Length Theory (FLT) and Collision Factor Theory (CFT). The validity of these relations and theories were tested by comparing the computed sound velocities with experimental values. Further, the molecular interaction parameter (α) was computed by using the experimental and the theoretical ultrasonic velocity values. The variation of this parameter with composition of the mixtures has been discussed in terms of molecular interaction in these mixtures.

Ultrasonic Study of Substituted Thiazoles at Different Temperatures

“…Most important features of ultrasonic systems are rapidity, robustness, non-invasiveness and high precession.The concentration and temperature dependance of acoustical and thermodynamical properties like adiabatic compressibility, linear free length, acoustic impedance and relative association etc. have proven immense value in predicting nature and strength of molecular intercation in liquid medium [3][4][5] . Heterocyclic compunds provide a great varsatility due to their having number of potential substitution and possibility of formation complexes with metal ions [6][7][8] .…”
