A STUDY ON MIXING PROPERTIES OF BINARY-MIXTURES OF 2-METHOXYETHANOL WITH AROMATIC-HYDROCARBONS

The volume of mixing, speed of sound, and viscosity of the binary mixt ures of 2-methoxyethanol + benzene, + toluene, + chlorobenzene, + brom obenzene, and + nitrobenzene have been measured at 303.15 K, over the entire mole fraction range. The results are used to derive densities a nd isentropic compresibilities. Excess volumes are positive over the w hole range of compositon, except for the mixture containing chlorobenz ene in which V-E shows negative values at higher mole fractions of 2-m ethoxyethanol and deviations in the compressibility exhibit an inversi on in sign in all the systems except for the mixture containing toluen e, in which it is always positive. Deviations of the viscosity from a mole fraction overage are negative except for the mixture containing b romobenzene in which the deviation is positive at higher mole fraction s. The results are fitted to the Redlich-Kister polynomial relation an d are presented as a function of composition.
