ISOBARIC VAPOR-LIQUID-EQUILIBRIA OF METHANOL PLUS METHYL ETHANOATE, PLUS METHYL PROPANOATE, AND PLUS METHYL BUTANOATE AT 141.3 KPA

Isobaric vapor-liquid equilibrium data at 141.3 kPa for the binary sys tems methanol + methyl ethanoate, + methyl propanoate, and + methyl bu tanoate are presented. All mixtures show positive deviations from idea lity but only the mixtures methanol + methyl ethanoate and methanol methyl propanoate show a minimum temperature azeotrope. The results ar e tested for thermodynamic consistency and correlated with several equ ations. The results are compared with the predictions of the ASOG and UNIFAC methods.
