T-x-y data for binary systems containing methyl ethanoate + n-butyl alcohol and methyl ethanoate + iso-butyl alcohol were measured at 74.66 and 127.99 kPa using a dynamic method. No azeotrope was found and the mixtures studied exhibited positive deviations from ideality. All data, p-T-x-y were found to be thermodynamically consistent and application of the group contribution models ASOG and UNIFAC gave good predictions.
