摘要：Isobaric vapor-liquid equilibrium (VLE) data for the dimethyl oxalate + methanol and methanol + 1,2-butanediol binary systems, as well as the VLE for the dimethyl oxalate + methanol + 1,2-butanediol ternary system have been determined using an Ellis equilibrium distiller at 101.325 kPa. The thermodynamic consistency tests of the two binary experimental VLE data for dimethyl oxalate + methanol and methanol + 1,2-butanediol were performed according to a statistical method and Herington's method. The two binary experimental data were correlated by the Wilson, nonrandom two-liquid and universal quasi-chemical activity coefficient models integrated in the authorized Aspen Plus software with the maximum average absolute deviations of 1.23 K for temperature and 0.389 for vapor phase composition. And the binary component interaction parameters were also obtained by this regression. On the basis of these calculated results, the corresponding binary interaction parameters of the dimethyl oxalate and 1,2-butanediol was then regressed from experimental ternary (dimethyl oxalate + methanol +1,2-butanediol) VLE data. These experimental and calculated data are valuable for the separation process design and optimization of dimethyl oxalate hydrogenation to ethylene glycol.
