Density measurements of 2-propanol solutions in supercritical CO2

Using a vibrating-tube densitometer, densities of 2-propanol solutions with compositions between (0.72 and 1.89) mol % in supercritical CO2 have been measured isothermally at (40, 50, 60, and 70) degreesC at pressures to 34.4 7 MPa. These measurements span the temperature and pressure ranges of earli er neutron scattering studies of the supercritical CO2 fluids, and density data are needed to interpret the results. In addition, these results should aid in using supercritical CO2 for separation or processing with 2-propano l and for improving the broad database supporting supercritical fluid techn ologies in general.
