ABSTRACT

Vapor-liquid equilibria (VLE) of binary mixtures containing methanol, ethanol, propanol-1, and benzene in the ionic liquid [BMIM][OctS] or [OMIM][BF4] 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 i of these solvents in the ionic liquids and osmotic coefficients i of the ionic liquids have been determined from the VLE data and are described formally by using the NRTL equation.
