Experimental isothermal vapour+liquid equilibrium (VLE) data are reported for the binary mixture containing 1-butyl-3-methylimidazolium chloride ([bmim]Cl) + 1-butanol at three temperatures: (353.15, 363.15, 373.15) K, in the range of 0-0.17 liquid mole fraction of [bmim]Cl. Additionally, refractive index measurements have been performed at three temperatures: (298.15, 308.15 and 318.15) K in the whole composition range. Densities, excess molar volumes, surface tensions and surface tension deviations of the binary mixture were predicted by Lorenz-Lorentz (nD-rho) mixing rule as well as dielectric permittivities and their deviations by known equations. Both types of experimental data were correlated using the Redlich-Kister models by means of maximum likelihood method
