| Abstract: | The isobaric vapor-liquid equilibrium data of the binary system dimethyl carbonate-dimethyl oxalate was measured by using a vapor-recycled vapor-liquid equilibrium still. Integral method was used to examine the thermodynamic consistency. The constants of Antoine equation for dimethyl oxalate were correlated by the data from literature. The activity coefficient of the liquid phase was correlated by the Wilson equation and satisfactory correlation result of the experimental data was obtained. |
