Hydrogenolysis of methyltetrahydrofurane on platinum

Applied Catalysis, 1984
Abstract The hydrogenolysis of methyltetrahydrofuran on supported platinum of high and low dispersion (EUROPT-1 and sintered EUROPT-1) as well as on platinum black was studied in a flow reactor. Based on the variation of activity and selectivity with time on stream, space velocity and temperature, the different behaviour of the three catalysts is ...

Catalytic Hydrogenolysis of Glycerol

2008
Rhodium-based catalysts were evaluated for the hydrogenolysis of glycerol. The study was focused on the influence of pH and metal additives on catalyst activity and selectivity. Under basic conditions, 1,2-PDO was formed with high selectivity (> 90%). Traces of acetol and ethylene glycol were detected and lactic acid was observed at high pH.

Hydrogenolysis of cubane

Tetrahedron, 1986
Abstract On catalytic hydrogenation over Pd-C under normal conditions cubane ( 10 ) takes up 3 mol of hydrogen in a few hours. Bicyclo[2.2.2] octane ( 13 ) is formed as the main product, and tetracyclo[4.2.0.0 2,5 .0 3,8 ]octane (11, secocubane) and tricyclo[4.2.0.0 2,5 ]octane ( 12 ,nortwistbrendane) have been identified as intermediates.

Production of Biobutanediols by the Hydrogenolysis of Erythritol

ChemSusChem, 2012
AbstractThe hydrogenolysis of erythritol using an Ir–ReOx/SiO2 catalyst was performed for the production of butanediols, which are widely used as a raw material of polymers. The activity and selectivity to butanediols on Ir–ReOx/SiO2 was much higher than that on conventional hydrogenolysis catalysts.

Hydrogenolysis of Carboxylic Ortho Esters

The Journal of Organic Chemistry, 2022
It is demonstrated for the first time that carboxylic ortho esters may be reduced to acetals using hydrogen as the reducing agent. Hydrogenolysis was performed under mild conditions over commercially available hydrogenation catalysts (5% Pd/C and 5% Pt/C).

The Catalytic Hydrogenolysis of Benzylamine Derivatives

Tetrahedron, 1973
Abstract The hydrogenolysis of optically active ethyl 2-amino-2-phenylpropionate ( I ), its N-methyl ( II ), and N,N-dimethyl ( III ) derivatives was studied using Raney Ni and Pd as the catalysts. The Raney Ni catalysed hydrogenolysis of II and III , as well as the reaction catalysed by Pd, occurred predominantly with inversion of configuration ...
