Abstract

The density of homogeneous phase fluid mixtures for various carbon dioxide (CO2)/organic solvent systems was measured in homogeneous phase. Solvents included cyclohexane (C6H12), methylcyclohexane (C6H11CH3), and ethylbenzene (C6H5C2H5). Density measurements were performed using a high-pressure vibration type density meter equipped with a circulation pump and variable volume viewing cell which guarantee the homogeneity of mixtures. The density was measured at temperatures ranging from 313 K to 353 K and pressures up to 20 MPa, and the CO2 composition varied from (0 to 80) mol%. The obtained experimental data were correlated according to a density equation. The resulting correlation agrees well with the experimental data.
