Relative Permittivities and Refractive Indices of <i>γ</i>-Butyrolactone with <i>o</i>-Xylene and <i>m</i>-Xylene

Abstract

Relative permittivities and refractive indices of the binary systems γ -butyrolactone + o -xylene and γ -butyrolactone + m -xylene were measured at (288.15, 293.15, 298.15, 303.15, and 308.15) K. Deviations in relative permittivity, refractive index, molar refraction, and molar polarization were calculated according to several mixing rules. Calculations of apparent dipole moment and dipole moment of the pure liquids were also performed.
