Measurements and prediction of vle of methyl propanoate/ethanol/propan-1-ol at 114: 16 and 127: 99 kPa

Abstract

Isobaric vapor–liquid equilibria for binary mixtures of methyl propanoate with ethanol and propan-1-ol are obtained by using a small-capacity recirculating still at 114.66 and 127.99 kPa. In the thermodynamic treatment of the data, the vapor phase is considered nonideal and all systems show positive deviations of ideality. Predictions carried out by using group contribution methods UNIFAC and ASOG are in good agreement with the experimental results, with errors less than 7% in all cases.
