An internal pressures and enthalpy of six binary liquid mixtures 1,3-dioxolane with mono alkanols have been computed at 298.15K. Values of excess internal pressure (p_i^E) and excess enthalpy (H^E) have also been evaluated from the data of pure components. The values of excess functions provide an in-depth understanding of the intermolecular interactions between the components. The results have been compared with experimental values and good agreement has been found.
