Hydrierung im invertierten Zweiphasensystem scCO 2/H 2 O
Catalysis using an inverted scCO2/H2O biphasic system where the catalyst is immobilized in scCO2 as stationary phase and the substrate and product are contained in the aqueous phase, offers an interesting alternative to classical biphasic systems and enables the conversion of polar substrates, …

Katalytische Festphasensynthese in Gegenwart von komprimiertem Kohlendioxid
… of reaction rate in the presence of compressed CO2 compared to the reaction in organic solvent was observed. For PKR and hydrogenation, optimal conditions were found in XPL, whereas for BHR highest yields could be obtained using pure carbon dioxide. Apparently, for the reactions containing …

Nanopartikuläre Katalysatoren und neue katalytische Anwendungen auf Basis der Metalle Rhodium und Cobalt
… investigated in a continuous flow process with scCO2 as the mobile phase. Furthermore Raney Cobalt was tested within this work as an active and selective catalyst for the PKR.
