ABSTRACT

The vapour-liquid equilibria (VLE) date for the binary system of glycidyl butyrate (1) and epichlorohydrin (2) was studied at 100 kPa 88.66 kPa, 56 kPa. An azeotropic behavior has not been found in this work. The activity coefficients were obtained by the nonlinear least squares method based on minimization from the equilibrium data. Average relative deviations between calculated values and the experimental data of temperature are all lower than 0.99% for three models and three different pressures. The root mean square deviations (RMSD) of gas phase compositions and tempertures are all lower than 0.0099 and 1.1 K for 100 kPa , 0.0094 and 4.5 K for 88.66 kPa, 0.0095 and 3.7 K for 56 kPa. Thermodynamic consistency of the calculated data are checked by the Herrington method. The experimental VLE date are compared with the correlated values obtained by means of the NRTL,UNIQUAC, and Wilson models.
