摘要：

This paper reports excess molar enthalpies, H-m(E), and excess molar volumes, V-m(E), of the binary systems {propyl propanoate + o-xylene}, { propyl propanoate + in-xylene} and { propyl propanoate + p-xylene} at the temperature 298.15 K and atmospheric pressure, over the whole composition range. V-m(E) was calculated from the experimental measurement of the corresponding densities, while Hm was measured directly. The excess magnitudes were correlated to a Redlich-Kister type equation. Finally, we will discuss the results of the three mixtures studied here and by comparison with other binary systems containing propyl propanoate and a benzene-based compound previously published.
