OXIDATION OF LIMONENE IN HIGH PRESSURE CO_2 REACTION MEDIA: THE INFLUENCE OF PHASE BEHAVIOUR

摘要

The influence of the phase behaviour on the oxidation of limonene in supercritical CO_2 as the reaction medium with molecular oxygen as the primary oxidant and isobutyraldehyde as the sacrificial co-oxidant was explored. Results on the kinetic of the reaction are presented at different carbon dioxide pressures, so that the reaction mixture would either be biphasic or at a single supercritical phase. The effect of the phase behaviour on the rate and selectivity of the reaction was investigated.
