T. Avraam et al., A STUDY ON EXCESS VOLUMES AND DIELECTRIC-PROPERTIES IN THE GAMMA-BUTYROLACTONE PLUS P-XYLENE SYSTEM AT VARIOUS TEMPERATURES, Journal of chemical and engineering data, 43(1), 1998, pp. 51-54
Densities, relative permittivities, and refractive indices were measur
ed for the binary mixture gamma-butyrolactone + p-xylene from 288.15 K
to 308.15 K. The above quantities are represented with polynomial smo
othing curves. Excess volumes, as well as deviations of molar polariza
tion, were calculated and found to be negative, with a minimum at mole
fraction 0.5. The Kirkwood correlation factor was also calculated.
