Volumetric properties of H2O and D2O solutions in propylene carbonate at TÂ =Â (278.15, 288.15, 298.15, 308.15, and 318.15) K under atmospheric pressure

► Limiting partial molar volume of H2O or D2O in propylene carbonate (PC) at T >293.15 K is higher than the molar volume of water isotopologue. ► Water − PC affinity prevails over the affinity of solvent molecules to each other, especially, in the solution of D2O in PC. ► Water−PC affinity prevails over the affinity of solvent molecules to each other. This tendency becomes more pronounced in the solution of heavy water in PC. ► Excess molar volumes of (water + PC) undergo the negative-to-positive sign inversion with increasing temperature.
