DETERMINATION OF EXCESS VOLUMES OF BENZENE + ORTHO-TERPHENYL AT 288.15-K, 298.02-K, AND 302.78-K

Densities of benzene + o-terphenyl have been measured as a function of composition at 288.15, 298.02, and 302.78 K by means of the pyknometric method. The density of the supercooled melt of o-terphenyl has also been measured from 288.15 to 313.19 K. The excess molar volumes and the excess partial molar volumes of the components are evaluated from the densities measured. The excess volumes are all negative at these temperatures, and they are more negative when the temperature is increased. © 1979.
