Excess thermodynamic properties of binary mixtures of n-Alkanes with cycloalkanones

Abstract Molar excess enthalpies of the systems cyclopentanone/n-alkanes and cyclohexanone/n-alkanes at 298.15 K were determined by direct calorimetric measurements. Molar excess volumes of cyclopentanone and cyclohexanone/n-alkanes were determined at 298.15 and 308.15 K and of cycloheptanone/n-alkanes at 298.15 K by dilatometric measurements of volumes of mixing. The excess thermodynamic properties for a particular cycloalkanone increase with the chain length of the n-alkane, while for a given n-alkane, excess properties decrease as the size of the cycloalkanone increases.
