Densities and speeds of sound have been determined for the binary mixture (1-butylpyridinium tetrafluoroborate+methanol, or ethanol) over the temperature range 293.15K to 323.15K. From experimental values, excess volume and excess isentropic compressibility have been calculated. The mixtures give negative values for the excess properties. Besides, (vapour+liquid) equilibrium in isothermal conditions...
