N2 - The isobaric binary vapor-liquid equilibrium data of ethanol + glycerol and 1-propanol + glycerol systems were collected experimentally at two pressure levels of 16.0 and 101.3 kPa using modified Glass Othmer-Still. Refractometer index Bausch and Lomb ABBE-type was used to analyze the equilibrium samples of liquid and vapor phase compositions. The reliability of the experimental data determined in this study was conformed to the L-W thermodynamic consistency test method proposed by Wisniak (Ind. Eng. Chem. Res. 1993, 32(7), 1531-1533). The data were regressed with the Wilson, NRTL, and UNIQUAC equations. The deviations of temperatures and vapor phase compositions were given, and the results indicated that the average absolute deviations in temperatures and in vapor phase compositions were less than 0.5 and 1.1%, respectively, for both systems studied. Furthermore, the performance of predictive UNIFAC equation was found to be better at a pressure of 16 kPa than that of 101.3 kPa.
