Thermodynamic and Transport Properties of Aromatic Amine with Ketone in Nonpolar Solvent at 303.15, 308.15 and 313.15K
Keywords:
adiabatic compressibility, free length, free volume, internal pressure, Gibbs free energy, relaxation time, excess parametersAbstract
The ultrasonic velocity(U), density(Ï) and viscosity(η) measurements were carried out for the three organic ternary mixtures of aniline+1,4-dioxan+propanone , aniline+1,4-dioxan+butanone and + aniline+1,4-dioxan+Methyl Iso Butyl Ketone at 303.15, 308.15 and 313.15 K. From the measured value the derived acoustic and thermodynamic parameters namely adiabatic compressibility(β), free length(LF), free volume(VF), internal pressure(Ï€i) ,Gibbs free energy (ΔG) were evaluated. In addition, excess values of certain above parameters were also calculated. The above parameters were used to discuss the presence of significant interactions between the component molecules in the ternary mixtures. Observed excess values in the mixture indicate the existence of strong interactions in the system.
