EXCESS VOLUMES OF BINARY-MIXTURES OF ANISOLE WITH BROMOBENZENE, O-DICHLOROBENZENE, O-CHLOROANILINE AND P-DIOXANE AT 298.15, 303.15 AND 313.15-K

Excess molar volumes, VE, and partial molar volumes, Vi, have been calculated for binary liquid mixtures of anisole with bromobenzene, o-dichlorobenzene, o-chloroaniline and p-dioxane from the results of densities measured at 298.15, 303.15, 308.15 and 313.15 K over the entire range of composition. In the temperature interval studied the values of VE are positive for anisole + p-dioxane, anisole + bromobenzene and anisole + o-dichlorobenzene, whereas negative values are observed for anisole + o-chloroaniline. The negative VE for the latter system was due to specific interactions between mixing components. The positive VE for the remaining systems was ascribed to the dispersion-type interactions. © 1990.
