The thermophysical parameters, excess molar volume ( V E ), viscosity ( η ), and speed of sound ( u ), and Fourier transform infrared spectra have been measured for binary mixtures of 2-methoxyaniline with isomeric butanols (1-butanol, 2-butanol and 2-methyl-2-propanol) over the entire mole fraction range at 303.15, 308.15, 313.15 and 318.15 K. The excess isentropic compressibility, deviation in excess viscosity and excess Gibbs energy of activation of viscous flow have also been estimated and analyzed. The spectroscopic measurements confirm that the interaction between unlike molecules takes place through hydroxyl groups of the isomeric butanols. Good agreement is obtained between the excess quantities and spectroscopic data.
