A semi-flow type apparatus was used to measure the vapor-liquid equilibria (VLE) of CO2 with diethyl oxalate, ethyl laurate, and dibutyl phthalate binary mixtures at 308.15, 318.15, and 328.15 K over the pressure range from 1.4 to 13 MPa. New VLE data for CO2 with esters are presented and the Henry's constants were determined from these results. These VLE data were also correlated using the Soave-Redlich-Kwong and the Peng-Robinson equations of state with various types of the van der Waals, composition-dependent and Huron-Vidal mixing rules. It is shown that both equations of state with the van der Waals mixing rules and two adjustable parameters gave satisfactory correlation results. ? 2001 Elsevier Science B.V.
