Abstract
The compositions and densities of the liquid and vapor phases at equilibrium of the binary system CO 2 + 2-ethoxyethanol were measured in a high-pressure VLE apparatus at 313.2, 320.2 and 328.2 K and for pressures ranging from ambient up to ca. 10 MPa. These measurements are ideally suited for testing equation-of-state models. The recently developed non-random hydrogen-bonding (NRHB) model was used for correlating the experimental data by taking the intramolecular hydrogen bonding in account. A satisfactory agreement was obtained between experimental and calculated phase compositions and saturated densities.
