Excess enthalpies, vapor-liquid equilibrium data and surface tensions of the highly non-ideal associated mixtures formed by methanol or ethanol and propanal have been measured in the temperature range of 288.15-318.15 K. These mixtures show negative deviations from ideality, including a negative azeotrope for the methanol-propanal system in the methanol-rich region. The values for the excess enthalpies...
The excess molar enthalpies h Em of the ethanol-propanal system have been measured at 298.15 and 318.15 K by means of an isothermal flow calorimeter. The pressure-effect on the h Em values has been investigated in order to compare these data with low-pressure vapor-liquid equilibrium data previously reported for the ethanol-propanol system. Values for h Em are...
