Abstract
Isothermal vapor-liquid equilibrium data of four binary systems -carbon dioxide+pentane at 311.15 and 329.15K, +diethyl ether at 313.15K, +methyl terf-butyl ether at 310.15, 329.15 and 338.15K, and +1-pentene at 303.15, 313.15 and 328.60 K-were determined by using an apparatus with vapor and liquid alternative circulation over a pressure range from 0.5 to 9.1 MPa.
Experimental data were correlated by applying the Soave-Redlich-Kwong equation of state with the conventional quadratic mixing rule and the DDLC-EOS unified model based on the conformal reference state. Results show that both models correlate the present data satisfactorily.
