Oxidation catalysis in a supercritical fluid medium
The supercritical fluid (SCF) extraction technique was extended by its application to SCF-solid catalyzed reactions that otherwise take place in a two-fluid-phase reactor. Using CO/sub 2/ as a solvent, an alkylaromatic hydrocarbon such as toluene was contacted with air in the presence of solid metal redox or acid catalysts, and underwent partial oxidation to benzaldehyde, benzyl alcohol, and cresols. This process should result in more rapid rates of mass transfer and intrinsic reaction than is customary for such reactions at conventional conditions, and more efficient quenching of the oxidation at the desired products; in addition it should allow an easier product separation and a decrease in reaction temperature that will improve the yield to desired products.
