摘要：
Vapor-Liquid equilibrium data for binary system methyl butanoate + propan-2-ol were measured by a dynamic phase equilibrium apparatus at three different pressures of 74.66, 101.32 and 127.99 kPa. An azeotrope was found at low ester concentration, which decrease with the increase of the working pressure. In all cases studied, p-T-x-y data exhibit a positive consistency being correlated through a suitable equation. Good predictions are obtained by ASOG [1] and UNIFAC [2,3] methods and employing parameters corresponding to different alkanol/ester interactions. The mean overall errors for activity coefficients were smaller than 8% as expected.
