High-pressure vapor-liquid equilibrium data for (methyl propionate + carbon dioxide) and (propyl propionate (PP) + carbon dioxide) were measured at pressures from (1.00 to 12.00) MPa and temperatures in the range from (313.0 to 373.0) K. Experimental results were correlated with the Peng-Robinson equation of state with the two-parameter van der Waals mixing rule. At the same time, the Henry's coefficient and partial molar enthalpy change and partial molar entropy change of CO(2) during dissolution at different temperature were also calculated.
