- Abstract:
- The vapor-liquid equilibrium(VLE) data of 2-methoxyethanol-methyl glycollate binary system weremeasured under the pressure of 50mmHg by using a VLE still,and the obtained data satisfy the thermodynam-ic consistencies . Then the VLE data were correlated by NRTL\Wilson\UNIQUAC models,and the corre-sponding binary interaction parameters of these models were obtained. With these models associated with thebinary system of VLE data, the average relative deviations of temperature between calculated and experimentalvalues were 0.2215% ,0.2398% ,0.2374% respectively ; the average relative deviations of 2-methoxyethanol’s vapor mass fraction were 3.7216% ,3.4378% ,3.338% respectively.The simulation results are close to ex-perimental values and these models are suitable to be used for the engineering seperation design.
