【Abstract】 Solubilities of aluminum isopropoxide in supercritical propane were determined by weighing method using a flow apparatus at temperatures of 388 K and 403 K and at pressures from 21.5MPa to 30.5MPa. The experimental data were correlated satisfactorily by two empirical equations correlating to the density of supercritical propane. Formation of aluminum isopropoxide particles by the rapid expansion of supercritical fluid solution (RESS) technique was performed at two extraction temperatures, 388 K and 403 K. No significant differences of the morphology of product particles were observed under the different extraction conditions because of the small change of the solute concentration.更多还原
