F. Comelli et al., Excess molar enthalpies and excess molar volumes of binary mixtures containing dialkyl carbonates plus pine resins at (298.15 and 313.15) K, J CHEM EN D, 46(1), 2001, pp. 63-68
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.
