“…It is clear that all the substrates show very high conversion ([99%) over Ru(Phen) 2 Cl 2 and [Ru(Phen) 2 Cl-NH-MCM-41]. Use of water as solvent in reaction was found most effective in the hydrogenation of unsaturated ketone compare to the other solvents (n-butanol, methanol and iso-propanol) as the solubility of gaseous H 2 is more in water as compare to other organic solvent [20].…”

“…Maximum swelling was in DMF, followed by DMSO. Nevertheless, hydrogenation reactions were carried out in methanol, since the solubility of hydrogen is higher in this solvent compared to the others (0.068 mL hydrogen/mL of methanol; 0.037 mL of hydrogen/mL of DMF) [25][26][27].…”

2-(2 0 -Pyridyl)benzimidazole (PBIMH) was functionalized onto chloromethylated polystyrene beads crosslinked with 6.5 % divinylbenzene, and this solid support was then reacted with Na 2 PdCl 4 in methanol. The functionalized beads were then activated using sodium borohydride. The resultant polymer-supported [2-(2 0 -pyridyl)benzimidazole]palladium complex (PSDVB-PBIM-PdCl 2 ) and its activated form were characterized by various physicochemical techniques. XPS studies confirmed the ?2 oxidation state of palladium in the supported complex. The activated complex was found to catalyse the hydrogenation of various organic substrates including olefins, nitro and Schiff base compounds. Kinetic measurements for the hydrogenation of cyclopentene, cyclohexene and cyclooctene were carried out by varying temperature, catalyst and substrate concentration. The energy and entropy of activation were evaluated from the kinetic data. The catalyst showed an excellent recycling efficiency over six cycles without leaching of metal from the polymer support, whereas the unsupported complex was unstable as metal leached out into the solution during the first run.

“…Für reines 1-Dodecen wurde ein wesentlich höherer k l aWert bestimmt als für Wasser. Dieses Verhalten wird ebenfalls in der Literatur beschrieben [12,13]. Im Falle der binä-ren Mischung 1-Dodecen/Wasser liegt der k l a-Wert unterhalb des Werts von reinem Wasser.…”

Mass Transfer Phenomena in Micellar Multiphase Systems Investigated for a Hydroformylation ReactionGeneral aspects of the influence of mass transport phenomena in micellar multiphase systems are discussed and demonstrated on the example of the hydroformylation of a long-chain olefin. The dispersion state of the multiphase system was characterized to identify the occurring mass transport processes. Therefore, images were taken with an endoscopic technique and combined with conductivity measurements. Subsequently schematic concentration profiles were derived by with help of k l a value measurements in order to explain the occurring mass transfer processes. The influence of mass transport limitations on the hydroformylation reaction was estimated by kinetic measurements with varying stirrer rotation frequencies.
