ABSTRACT
The excess molar enthalpies of the carbon dioxide + dimethyl carbonate system were measured in the vicinity of the critical point of carbon dioxide using a flow-type isothermal microcalorimeter at temperatures of (298.15 to 308.15) K and pressures of (5.0 to 7.5) MPa. Mixtures showed 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 van der Waals one-fluid mixing rules.
