Abstract
Excess molar volumes, [Formula: see text], and excess molar heat capacities at constant pressure, [Formula: see text], have been obtained for some n-alkanone + n-alkane mixtures at 298.15 K from density and volumetric heat capacity measurements using liquid-flow techniques. The [Formula: see text] data are much more accurate than those estimated from the temperature dependence of other thermodynamic properties (excess free energies and/or excess enthalpies). The rather unusual composition dependence of the excess heat capacities — two minima, or W-shape curves — is most likely due to cooperative induced conformational molecular "arrangements" in these mixtures.
