The excess molar enthalpies of the carbon dioxide + diethyl carbonate system were determined using a flow-type isothermal microcalorimeter at temperatures from 298.15 to 308.15K and pressures from 5.0 to 6.5MPa. Mixtures shows strong exothermic behavior in these regions. In addition, a strong pressure dependency of the excess molar enthalpies was observed, and the excess molar enthalpy values decreased with increasing pressure. The experimental results were correlated using a composition-dependent equation and the Peng Robinson equation of state with the conventional mixing rule. Finally, the prediction of excess molar enthalpies using three mixing rules (MHV1, MHV2, and Wong Sandler) was also tested on the basis of the vapor liquid equilibrium data.
