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 mixtures of 2-methoxyethanol + benzene, + toluene, + chlorobenzene, + bromobenzene, and + nitrobenzene have been measured at 303.15 K, over the entire mole fraction range. The results are used to derive densities and isentropic compresibilities. Excess volumes are positive over the whole range of compositon, except for the mixture containing chlorobenzene in which V-E shows negative values at higher mole fractions of 2-methoxyethanol and deviations in the compressibility exhibit an inversion in sign in all the systems except for the mixture containing toluene, in which it is always positive. Deviations of the viscosity from a mole fraction overage are negative except for the mixture containing bromobenzene in which the deviation is positive at higher mole fractions. The results are fitted to the Redlich-Kister polynomial relation and are presented as a function of composition.
