“…Hence the observed deviation shows that the molecular interaction is taking place between the unlike molecules in the liquid mixture 13 . Similar kinds of results were obtained by earlier workers [14][15][16] . The agreement between experimental and theoretical velocities of Nomoto relation in all the three binary systems, suggests that R is additive property in all the systems.…”

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.

The Internal pressures of Ternary and their Sub-Binary liquid mixtures of benzene(1) + hexane(2) + sec-butyl alcohol(3) were calculated using density, velocity and molar refraction from the temperature range of 303.15K-318.15K. For the Binary liquid mixtures, the Experimental Internal pressure values were correlated through an equation proposed by Andiappan et.al. For the Ternary liquid mixture, the Experimental Internal pressure values were correlated through an equation proposed by us. The Experimental values and the Theoretical values are in close agreement with each other

“…In resent years measurement of ultrasonic investigations find extensive applications in determining the physicho-chemical behavior of liquid mixtures [1][2][3][4][5] . 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 11 , impedence relation 12 , Rao's Specific Velocity 13 and Junjie 14 and interpreted the results in terms of molecular interactions.…”

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.
