Thermodynamic properties of binary liquid systems of ethanoic acid, propanoic acid, and butanoic acid with 3-chloroaniline as a function of various temperatures

The densities (ρ) and viscosities (η) are reported for binary mixtures of 3-chloroaniline with carboxylic acids such as ethanoic acid, propionic acid and butanoic acid over the entire range of mole fractions at T = (303.15–318.15) K and at constant atmospheric pressure. The excess properties such as excess volume and deviation in viscosity are calculated from the density and viscosity data. Excess properties are correlated by the Redlich–Kister equation. The variations of these properties with the composition of binary mixtures suggest the loss of dipolar association, difference in size and shape of the component molecules, dipole–dipole interactions and hydrogen bonding between unlike molecules.
