Densities, Relative Permittivities, and Refractive Indices of the Binary Systems Propylene Carbonate + o-Xylene and Propylene Carbonate + m-Xylene at (15, 20, 25, 30, and 35) °C

Densities, relative permittivities, and refractive indices were measured at (15, 20, 25, 30, and 35) °C, over the whole composition range of the binary mixtures propylene carbonate + o-xylene and propylene carbonate + m-xylene. Excess volumes were found to be negative, and the values were fitted to a Redlich−Kister type equation. Apparent dipole moments were calculated, as well as deviations in relative permittivity, molar refraction, and molar polarization.
