Excess molar enthalpies and excess molar volumes of binary mixtures containing dialkyl carbonates plus pine resins at (298.15 and 313.15) K

Excess molar enthalpies, H-m(E), and excess molar volumes, V-m(E), of binar y mixtures containing dimethyl carbonate (DMC), or diethyl carbonate (DEC) + alpha -pinene, + beta -pinene, or + p-cymene have been determined using a flow microcalorimeter and a digital density meter at atmospheric pressure and at (298.15 and 313.15) K. All H-m(E) and V-m(E) data are positive and s how symmetrical curves versus composition. The influence of temperature is marked for volumetric measurements while almost negligible for enthalpic da ta. Results have been correlated using the Redlich-Kister polynomial to est imate the binary interaction parameters. The calculated quantities have bee n qualitatively discussed in terms of thermodynamic interactions between th e mixing compounds.
