BIPHASIC HYDROGENATION AND ISOMERISATION OF TERPENES IN SUPERCRITICAL CARBON DIOXIDE

摘要

Terpene + supercritical carbon dioxide (scCO_2) systems are interesting model systems to determine the factors that control heterogeneous catalysis in biphasic vs. monophasic conditions. Based on this idea, hydrogenation and isomerisation of different terpenes with carbon-supported catalysts was performed in the presence of high-pressure carbon dioxide. Experiments were performed at different carbon dioxide pressures, so that the reaction mixture would be either two-phase (liquid + gas) or one (supercritical) phase.
