Vapor-Liquid Equilibrium Data of the Carbon Dioxide plus Ethyl Butyrate and Carbon Dioxide plus Propylene Carbonate Systems at Pressures from (1.00 to 13.00) MPa and Temperatures from (313.0 to 373.0) K
High-pressure vapor-liquid equilibrium data for the binary systems of ethyl butyrate (EB) + carbon dioxide and propylene carbonate (PC) + carbon dioxide were measured. The experimental pressure range was from (1.00 to 13.00) MPa and the temperature 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 solution enthalpy and solution entropy of CO(2) during dissolution at different temperature were also calculated.
