- Abstract:
- In orderto separate 1，2一propyleneglycol and ethylene glycol，the methodof only vapor phase cir— culation wasused to measure vapor—liquid equilibrium values at 6．67 kPa．And the experimental data of the binary system measured in this work passed the thermodynamic consistency test according to Herington area method．The experimental data of the binary system were correlated by Wilson，NRTLandUNIQUAC activity coefficientmodels．And all the models showed rather smaller deviation from the experimental results，indica— ting that the experiment data are suitable for the further industry process design．
