Excess molar enthalpies for binary carbon dioxide + diethyl carbonate system at 298.15-308.15 K and 5.0-6.5 MPa
چکیده انگلیسی
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 308.15 K and pressures from 5.0 to 6.5 MPa. 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.
