Density (ρ), refractive index (n), ultrasonic velocity (u), and viscosity (η) were measured for the binary mixtures formed by butylamine with 1-butanol and tert-butanol at temperatures 293, 303, and 313 K over the entire composition range. Excess molar volume V_m^E, molar refraction deviation ΔR_m, deviation in ultrasonic velocity Δu, viscosity deviation Δη, and excess Gibb's free energy of activation for viscous flow ΔG^{*E} were derived from the experimental data and the computed results were fitted to the Redlich-Kister polynomial equation. The values of V_m^E, ΔR_m, Δu, Δη, and ΔG^{*E} were plotted against the mole fraction of butylamine. The observed positive and negative values of excess parameters for both the mixtures were explained on the basis of intermolecular interactions present in these mixtures. The higher negative values of V_m^E and ΔR_m and positive values of Δu, Δη, and ΔG^{*E} for butylamine + 1-butanol mixture suggest that specific interactions are taking place in butylamine + 1-butanol mixture, while weak dipole-dipole induced forces and dispersive forces seem to be responsible for butylamine + tert-butanol mixture. Furthermore, different empirical relations were used to correlate the binary refractive indices. An excellent agreement was found between experimental and theoretical values.
