Some thermodynamic properties of the system benzene ‐ 1,2‐dichloroethane. Part III: The excess molar volumes

The excess molar volumes on mixing benzene and 1,2‐dichloroethane have been measured at 20.00°C, 30.10°C, and 50.00°C. It appears that the excess molar volumes are of the order of 0.25 ml/mole at equimolar concentrations. A small temperature dependency has been observed. Finally some conclusions concerning this sytem have been drawn.
