  Thermoacoustic Properties of Ethanol-n-Hexane and 1-Propanol-n-Hexane Binary Mixtures: A Comparative Study at 298.15 K

  By Dr. Ashish Wakulkar, Shah S. A., Priyanka bhukya, Ban P. W.

  Abstract: Using an Anton Paar DSA 5000 M instrument, measurements of density, sound velocity, and viscosity were carried out for ethanol–n-hexane and 1-propanol–n-hexane binary mixtures across mole fractions ranging from 0.1 to 0.9 at a constant temperature of 298.15 K. These binary mixtures were specifically selected to investigate the behavior of polar–nonpolar molecular interactions and how they affect the thermophysical properties of the system. The density, sound velocity, and viscosity data …

  Temperature-Dependent Acoustic and Thermodynamic Investigation of Molecular Interactions in the 1-Propanol–n-Hexane Binary Mixture

  By Wakulkar A. P., Lanjewar M. R., Shah S. A., Bhukya P. P.

  Abstract: The present study investigates the molecular interactions and thermophysical behavior of the binary mixture comprising 1-propanol and n-hexane over the temperature range of 288.15–318.15K. The experimental determination of density (ρ), viscosity (η), and ultrasonic velocity (u) was carried out over the entire composition range, and the measured data were utilized to evaluate several acoustical and thermodynamic parameters, including the Van der Waals constant, relaxation strength, acoustic impedance, Rao’s constant, Wada’s …

  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

  By 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 …
