The catalytic properties of Pd and Pt supported on woven glass fibers (GF) were investigated in the three-phase hydrogenation of nitrobenzene (NB). Over all catalysts, a 100% yield of aniline was attained. The catalytic activity for the best catalysts was ...
Addnl. data considered in abstracting and indexing are available from a source cited in the original document. The effect of varying the feed concn. as a periodic rectangular function was studied in the hydrogenation of C2H4 in a fixed bed of an Al2O3-Pt c ...
CO2 hydrogenation over catalysts is a potentially exciting method to produce fuels while closing the CO2 cycle and mitigating global warming. The mechanism of this process has been controversial due to the difficulty in clearly identifying the species pres ...
Optimal conditions for chlorotris(triphenylphosphine)rhodium(I) (Wilkinson's catalyst) catalyzed selective satn. of a double bond in the presence of a nitro function are developed. Aryl iodide and benzyl ether are also tolerated under these hydrogenation c ...
The lithium enolate of (-)-6-endo-chloro-5-exo-(phenyl-seleno)-7-oxabicyclo[2.2.1]heptan-2-one ((-)-4) added to (+)-(3aR, 4aR,7aR,7bS)-3a,4a,7a,7b-tetrahydro-6,6-dimethyl[1,3]dioxolo[4,5]furo[2, 3-d]isoxazole-3-carbaldehyde ((+)-5) giving a major aldol (+) ...
Structured palladium catalysts suitable for three-phase reactions have been developed based on woven fabrics of active carbon fibers (ACF) as the catalytic supports. The Pd/ACF were tested in liq.-phase hydrogenation of 2-butyne-1,4-diol showing a selectiv ...
A model based on fluid dynamics is proposed, which describes the dynamics of a photoinduced spherical deformation in solid hydrogen. The dynamics is driven by femtosecond excitation of the lowest A(3ss) Rydberg state of NO trapped in an H2 crystal, leading ...
Excitation of the A(3ss) Rydberg state of NO trapped in an H2 crystal leads to the electronic bubble formation around the NO impurity, resulting in an increase of 0.9 .ANG. of the ground state cage radius. Its dynamics was followed in real-time by femtosec ...
