Comparative Study of Molecular Interactions in Binary Liquid Mixtures of 4-Methyl-2-Pentanone with Aniline, N, N-Dimethyl Aniline and Chlorobenzene at 308 K

D. Ubagaramary

Abstract


The ultrasonic velocity (u), density (ρ) and viscosity (η) have been restrained for binary mixtures of 4-methyl-2-pentanone with butan-2-one, cyclohexanone and furfuraldehyde at temperature T=308K at changed mole fractions. The experimental data have been used to calculate the acoustical and thermo-dynamical parameters like adiabatic compressibility (βad), free length (Lf), free volume (Vf), internal pressure (πi), acoustical impedance, Gibb’s free energy and their excess volumes in particular, it is seen that the response of these parameters to frequency is less prominent in to comparison to that of the binary mixtures containing 4-methyl-2-pentanone with butan-2-one, cyclohexanone and furfuraldehyde. Molecular interface studies with ultrasonic method in the binary liquid mixtures of 4-methyl-2-pentanone+butan-2-one, 4-methyl-2-pentanone+cyclohexanone and 4-methyl-2-pentanone+furfuraldehyde have been conceded out at 308 K. Using the dignified values of ultrasonic velocity, density and viscosity, acoustical parameters and their additional values are estimated. The necessity of glut properties of mixture compositions were associated and discuss in terms of the intermolecular free length and other elements moving the salvation and self-association effect. From the belongings of these glut parameters the nature and strength of the interfaces in these binary systems are discussed.
