The (CO2 + 2-ethoxyethyl acetate) and (CO2 + 2-(2-ethoxyethoxy)ethyl acetate) systems at 313.2, 333.2, 353.2, 373.2 and 393.2 K as well as pressures up to 20.59 MPa have been investigated using variablevolume high pressure view cell by static-type. The solubility curve of 2-ethoxyethyl acetate and 2-(2-ethoxyethoxy)ethyl acetate in the (CO2 + 2-ethoxyethyl acetate) and (CO2 + 2-(2-ethoxyethoxy)ethylacetate) systems increases as the temperature increases at a constant pressure. The (CO2 + 2-ethoxyethylacetate) and (CO2 + 2-(2-ethoxyethoxy)ethyl acetate) systems exhibit type-I phase behavior. The experimental results for the (CO2 + 2-ethoxyethyl acetate) and (CO2 + 2-(2-ethoxyethoxy)ethyl acetate) systems correlate with the Peng.Robinson equation of state using a van der Waals one-fluid mixing rule including two adjustable parameters. The critical properties of 2-ethoxyethyl acetate and 2-(2- ethoxyethoxy)ethyl acetate are predicted with the Joback-Lyderson group contribution and Lee-Kesler method.
