摘要：

Vapor-liquid equilibria (VLE) of binary mixtures containing methanol, ethanol, propanol-1, and benzene in the ionic liquid [BMIM][OctS] or [OMIM][BF(4)] were studied by using a static method. VLE measurements were carried out over the whole concentration range at four different temperatures in the range from 298.15 K to 313.15 K. Activity coefficients gamma(i) of these solvents in the ionic liquids and osmotic coefficients phi(i) of the ionic liquids have been determined from the VLE data and are described formally by using the NRTL equation.
