Theoritical Evaluation of Ultrasonic Velocities in Binary Liquid Mixtures of N‐Methyl‐2‐pyrrolidone at Different Temperatures with Some Cyclic Compounds

Abstract

Ultrasonic velocities and densities of the binary liquid mixtures of N-methyl-2-Pyrrolidone (NMP) with Cyclohexylamine (CHA), Cyclohexanol (CHOL) and Cyclohexene(CHE) at a temperature range of 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(U NR ), Impedence relation(U IR ), Ideal mixing relation(U IMR ), Jungie's relation(U JR ) and Rao's specific velocity relation(U R ).The molecular interaction parameter (α) was computed by using the experimental and theoretical ultrasonic velocity values. The variation of interaction parameter with the composition of the mixture has been discussed in terms of molecular interactions.

Evaluation of Theoretical Velocities and Comparative Study of Ultrasonic Velocities in Binary Liquid Mixtures of Ethyl Lactate with Branched Alkanols at Different Temperatures

“…The present work is a continuation of our research programme on a comparison of experimental ultrasonic velocity with the theoretical models of Nomoto, impedance relation, Van Dael ideal mixing relation, Rao's specific velocity and Junjie's relation for the binary mixtures of several systems at various temperatures by our researchers. The results are interpreted in terms of intermolecular interactions between the binary component liquid mixtures [10][11][12][13][14][15][16][17][18] . In this paper, we report the experimental and theoretical ultrasonic velocities of the binary liquid mixtures of ethyl lactate with 2-propanol, 2-butanol and 2-methyl,1-propanol at 303.…”

Theories of Ultrasonic Velocities and their Application in Binary Liquid Mixtures of N-Ethylaniline with Some Toluenes (Toluene, o-Nitrotoluene and m-Nitrotoluene)

“…Several researchers [6][7][8][9] carried out ultrasonic investigations and correlated the experimental results of ultrasonic velocity with the theoretical relations of Nomoto 10 , Van Deal and Vangeel ideal mix relations 11 impedance relation 12 Rao's Specific velocity 13 and Junjie 14 and interpreted the results in terms of molecular interactions. Ultrasonic study of liquid mixtures, due to its non destructive nature, has been extensively carried out in different branches of science to measure the thermodynamic properties and to predict the nature of molecular interaction between the molecules in a medium.…”

Theoretical Evaluation of Ultrasonic Velocities in Binary Liquid Mixtures of Anisaldehyde with Some Alcoxyethanols at Different Temperatures

“…Several researchers [6][7][8][9] carried out ultrasonic investigations and correlated the experimental results of ultrasonic velocity with the theoretical relations of Nomoto [10,11], van Deal and Vangeel ideal mix relations [12] impedance relation [13] Rao's Specific velocity [14] and Junjie [15] and interpreted the results in terms of molecular interactions. There has been an increasing interest in the study of intermolecular interactions in the last two decades and numbers of experimental techniques have been used to investigate the interactions between the binary liquid mixture components.…”
