Resumen:
Vapor−liquid equilibrium data were measured for thecarbon dioxide + ethyl n-butyrate (EB) binary system at high-pressures. Fiveisotherms are reported at (333.15, 343.15, 353.15, 363.15, and 373.15) K andpressures up to 121.75 bar. A static-analytical methodwith phasessampling was used. The new experimental results are compared with existing literaturedata and discussed. Inorder to provide a continuous and consistent description of the system phasebehavior, unique sets of interaction parameters for different approaches withthe Peng-Robinson (PR) equation of state (EoS) and classical van der Waalsmixing rules were obtained. A constant kijvalue of -0.048 is recommended, providing an excellent description of the datareported in this work, especially for the liquid phase. Predictions are also comparedwith the other available literature data and discussed.
