Relative permittivities (ε) at five temperatures, between (293.15 and 313.15) K, viscosities (η) at three temperatures, between (293.15 and 303.15) K, and speeds of sound ( u ) at 298.15 K of binary mixtures of 2-methoxyethanol (1) + butylamine (2) are reported. From all those data, the deviations from mole fraction additivity of the relative permittivity (Δε), viscosity (Δη), and speed of sound (Δ u ) were calculated and fitted to a Redlich−Kister equation.
