phase behavior for the binary mixtures of isoalkyl acetate in supercritical CO2 |
| 초록 |
High pressure phase behavior for the CO2 + isobutyl acetate, CO2 + isopentyl acetate and CO2 + isooctyl acetate systems are measured on a variadle view cell apparatus at various temperatures of 313.2 K to 393.2 K and pressures up to 18.24 MPa. These three systmes exhidit maximums in pressure at temperatures of these systems with the critical temperatures. these systems have continuous critical mixture curves that ehibit maximums in pressure - temperture (P-T) space between the critical tempertures of CO2 and isobutyl acetate or isopentyl acetate or isooctyl acetate. The solubility of CO2 for three systems decreases se the temperature increases at a constant pressure. The experimental results for three systems are correlated with the Peng-Robinson equation of state using a mixing rule including binary interaction parameters. |
