Thermodynamic properties of aqueous 1,3-propanediol binary mixtures at different temperature

In this paper, volumetric properties of water and 1,3-propanediol binary liquid systems include the densities, excess molar volume, partial molar volume and thermal expansion coefficient were determined at whole concentration range and atmospheric pressure and three temperatures of 298.15, 303.15, and 308.15 K. Using the plots of the obtained thermodynamic parameters values against the temperature and concentration, non-ideal behavior of amine mixture and molecular interaction have been analyzed.
