Study of Thermodynamic and Transport Properties for Binary Mixtures of 4-Methyl-2-pentanone and Meta-substituted Aniline Systems with PFP Theory and Correlation with the Jouyban-Acree Model at 303.15, 308.15, and 313.15 K

Excess molar volume, excess isentropic compressibility, deviation in viscosity and excess Gibbs free energy for activation of viscous flow for binary mixtures of 4-methyl-2-pentanone with meta-substituted aniline (3-chloroaniline, 3-methoxyaniline and 3-methylaniline) at selected compositions were determined from the measured values of densities (rho), viscosities (eta), and speeds of sound (u) of pure components and their mixtures from 303.15 to 313.15 K. The results are analyzed in terms of interactions arising due to electron donation-acceptance in the binary mixtures. Prigogine-Flory-Patterson (PFP) theory is applied to identify the predominant molecular interactions. Results of Jouyban-Acree model are discussed in terms of mean relative deviation (MRDs) and individual relative deviation (IRD) between the calculated and experimental densities and speeds of sound as an accuracy criterion.
