Abstract
The high-pressure phase equilibria of carbon dioxide+benzaldehyde binary system were measured at temperatures from 298.55 to 345.15K and pressures from 2.20 to 14.96MPa. The experimental method used in this work was a static-analytical method with liquid and vapor phase sampling. The experimental results are discussed and compared with available literature data. The experimental data were correlated with the Peng–Robinson equation of state (PR EoS) using classical van der Waals (two-parameter conventional mixing rule) mixing rules, which could correlate well the binary phase behavior with an average absolute relative deviation of 3.4%.
