ABSTRACT
The solubility of diisopropoxititanium bis(acetylacetonate) (DIPBAT) in supercritical carbon dioxide was measured using a dynamic method. Measurements were performed at (353, 423, and 473) K over the pressure range from (10 to 20) MPa. The measured mass fraction solubility varies between 5 deg 10-4 and 7.4deg 10-2 . In the range of pressures and temperatures of the measurements, the solubility increases at higher pressures and decreases at higher temperatures. Results were correlated by the Chrastil equation and the Peng-Robinson equation of state.
