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 binary 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 show symmetrical curves versus composition. The influence of temperature is marked for volumetric measurements while almost negligible for enthalpic data. Results have been correlated using the Redlich-Kister polynomial to estimate the binary interaction parameters. The calculated quantities have been qualitatively discussed in terms of thermodynamic interactions between the mixing compounds.
