Abstract
Densities and ultrasonic velocities of Aniline in cyclohexane + Dimethyl ketone and Aniline in cyclohexane + ethyl methyl ketone of these ternary mixtures of different compositions have been determined experimentally at 303 and 313 K. The results obtained from density and ultrasonic velocity measurement have been used to calculate the acoustical parameters such as, adiabatic compressibility (Ks), free Length (Lf ) , and acoustic impedance (Z). The results are discussed in terms of the intermolecular hydrogen bonding and molecular association in these ternary systems.
Highlights
We present in this paper, the study of interaction between Aniline in cyclohexane + Dimethyl ketone and Aniline in cyclohexane + ethyl methyl ketone of these ternary mixtures
We report densities, (ρ) and ultrasonic velocity (u) of Aniline in cyclohexane + Dimethyl ketone and Aniline in cyclohexane + ethyl methyl ketone of these ternary mixtures of different compositions have been determined experimentally at 303 and 313 K
The density and ultrasonic velocity decrease with increase in temperature which indicates the changes in structure occurring in the mixtures as a result of H- bond formation lead to decrease in intermolecular forces [11] due to increase in thermal vibration of the ternary system, which causes an increase in volume expansion and increase in free path length
Summary
We present in this paper, the study of interaction between Aniline in cyclohexane + Dimethyl ketone and Aniline in cyclohexane + ethyl methyl ketone of these ternary mixtures. We report densities, (ρ) and ultrasonic velocity (u) of Aniline in cyclohexane + Dimethyl ketone and Aniline in cyclohexane + ethyl methyl ketone of these ternary mixtures of different compositions have been determined experimentally at 303 and 313 K. From these experimental data a number of acoustical parameters namely, adiabatic compressibility (Ks), free Length (Lf) and acoustic impedance (Z) respectively have been calculated. These parameters were utilized to study various interactions taking place in ternary mixtures at 303 and 313 K
