Vapor-liquid equilibrium data were measured isothermally in the vicinity of azeotropic points of the title system at 333.15, 343.15, and 353.15 K. Data were processed using a newly-developed method based on relatively small amounts of input data, which provides thermodynamic description of azeotropic behavior. The regular two -parameter Redlich-Kister equation was used for this purpose. The parameters obtained were correlated with ionic liquid concentrations to express the smooth analytical dependence of both the azeotropic composition and pressure.
