The excess molar enthalpies of (propylene carbonate + methanol), (propylene carbonate + ethanol), and (propylene carbonate + 1-propanol) were measured at T = (298.15 and 323.15) K. All the systems showed endothermic behaviour over the whole experimental conditions, which means that the interactions between like molecules are stronger. The (1-propanol + propylene carbonate) showed the largest excess molar enthalpies compared with methanol and ethanol. As the temperature increased from T = (298.15 to 323.15) K, the excess molar enthalpies also increased over all the systems. The experimental results were fitted with the Redlich-Kister equation with a reasonable accuracy.
