Effects of solvents polarity parameters on heterogeneous catalytic hydrogenation of cyclohexene in molecular solvents
Heterogeneous catalytic hydrogenation of cyclohexene, catalyzed by Pt/A1203, was carried out in thirteenvarious solvents (four alcoholic solvents, six aprotic polar solvents and three non polar solvents) at 25 °C.Single-parameter correlations of logk vs. normalized polarity parameter (ETN), hydrogen-bond acceptorbasicity (p), hydrogen-bond donor acidity (a) and dipolarity/polarizibility (it*) d...

متن کاملModel studies of heterogeneous catalytic hydrogenation reactions with gold.
Supported gold nanoparticles have recently been shown to possess intriguing catalytic activity for hydrogenation reactions, particularly for selective hydrogenation reactions. However, fundamental studies that can provide insight into the reaction mechanisms responsible for this activity have been largely lacking. In this tutorial review, we highlight several recent model experiments and theore...
متن کاملThe Catalytic Hydrogenation 2,4_dinitrotoluene in a Continuous
Abstrati-An experimental study of the catalytic hydrogenation of 2,4_dinitrotoluene (DNT) in a miniinstallation with a continuously operated stirred three-phase slurry reactor and an evaporating solvent is discussed_ Some characteristic properties of the reactor system and the influence of the operating parameters on the performance of the reactor are illustrated. The experimental results are c...
متن کاملInfluence of adsorption geometry in the heterogeneous enantioselective catalytic hydrogenation of a prototypical enone
The Pd(111) crystal was attached to a motorized manipulator using tantalum wires and could be heated by means of electron bombardment to 900 K or cooled to 77 K, as monitored by a T1T2 thermocouple attached directly to the sample. It was cleaned by cycles of Ar sputtering (4 keV, 7 μA) and annealing (850 K) followed by brief heating to ~ 850 K in the presence of 2×10 mbar of O2 to remove residu...
