Volumetric Behavior and Saturated Pressure for Carbon Dioxide + Ethyl Acetate at a Temperature of 313.15 K

Abstract

Volumetric property was measured for carbon dioxide + ethyl acetate at T = 313.15 K and pressures to 10 MPa. Saturated pressure was also measured by the synthetic method. The experimental data obtained were correlated with various equations of state.

Correlation of High Pressure Density Behaviors for Fluid Mixtures made of Carbon Dioxide with Solvent at 313.15 K

“…As the volume of cell is changed, the volumetric properties of the mixture can be measured at a fixed and known composition The reliability of the experimental procedures had been confirmed by the agreement between the synthetic bubble point pressure measurements with the present apparatus and the analytical vapor-liquid equilibrium measurements in the separate conventional apparatus [4,7]. The high pressure density behaviors for fluid mixtures made of carbon dioxide with methyl acetate, ethyl acetate, 2-propyl acetate, methanol, 1-propanol, or 2-propanol at 313.15 K were measured by the authors [1][2][3][4][5][6]. For carbon dioxide+ethyl acetate, the density data reported by Smith et al [8] deviated 0.8 kg m -3 from the experimental ones reported by the authors [2].…”

“…The apparatus was described previously [1][2][3][4][5][6]. The maximum operating temperature and pressure of the apparatus are 400 K and 20 MPa, respectively.…”

“…The high pressure density data [1][2][3][4][5][6] of the six fluid mixtures made of carbon dioxide with methyl acetate, ethyl acetate, 2-propyl acetate, methanol, 1-propanol, or 2-propanol at 313.15 K have been correlated by the following density Eq.…”

“…Methyl acetate, ethyl acetate, 2-propyl acetate, methanol, 1-propanol, and 2-propanol are typical worthy solvents in chemical industry. The authors [1][2][3][4][5][6] therefore measured the high pressure density behaviors for fluid mixtures made of supercritical carbon dioxide with those solvents. In the previous studies, an equation for the correlation of density behaviors of fluid mixtures at high pressures was presented.…”
