Abstract

The best of both worlds: Phase changes in ionic liquid + water systems, induced by addition of ethanol and supercritical carbon dioxide, allow reaction cycles to proceed as depicted, combining the high rates of one-phase conditions with easy separation of products; characteristic of biphasic catalysis. The (usually slow) epoxidation of isophorone by hydrogen peroxide, catalysed by sodium hydroxide, was rapidly carried out in these conditions, with complete recovery of the reaction product by supercritical CO2 decompression.
