Abstract

The experimental densities at T = (298.15 to 318.15) K, speeds of sound, and relative permittivities at T = (298.15 and 308.15) K are measured for the six ternary mixtures: methyl methacrylate (1) + 2-butoxyethanol (2) or dibutyl ether (2) + benzene (3), toluene (3), and p-xylene (3). Excess molar volumes, excess isentropic compressibilities, and deviations in molar polarizations are calculated. The above functions of ternary systems were also calculated using the data of constituent binary pairs and employing Redlich−Kister, Tsao and Smith, and Kohler equations. Compared to others, the Redlich−Kister equation has been found to reproduce the experimental excess molar volumes adequately, while excess isentropic compressibilities and deviations in molar polarizations of the above ternary mixtures could not be adequately calculated using the respective binary contributions.
