A robust iron catalyst for the selective hydrogenation of substituted (iso)quinolones

Solvent-free selective hydrogenation of chloronitrobenzene to chloroaniline over a robust Pt/Fe3O4 catalyst.

In the absence of solvent, highly selective hydrogenation of o-chloronitrobenzene and m-chloronitrobenzene, with selectivity to the corresponding chloroanilines of ≥99.4% and complete conversion of the substrates, was realized over a robust Pt/Fe(3)O(4) catalyst which was prepared by adsorbing Pt nanoclusters on a Fe(3)O(4) support.

Catalyst Development for Selective Hydrogenation of Functionalized Alkynes and Nitroarenes

On the mechanism of carbonyl hydrogenation catalyzed by iron catalyst.

Density functional theory calculations have been performed to investigate the detailed mechanism of the carbonyl hydrogenation catalyzed by the first well-defined bifunctional iron catalyst. The catalytic reaction proceeds by hydrogen transfer and dihydrogen activation. The hydrogen transfer reaction occurs via the bifunctional mechanism in which the two hydrogen atoms attached on the Fe and O ...

CFD modeling for selective formation of propylene from methanol over synthesized Mn-substituted MFI metallosilicate catalyst

The high silica Mn-substituted MFI metallosilicate catalyst with Si/Al molar ratio of 220 and Si/Mn molar ratio of 50 was successfully synthesized by hydrothermal method. The catalyst sample was appropriately characterized by XRD, FE-SEM, EDX and BET techniques. The Mn-substituted MFI metallosilicate has not been reported as the potential catalyst for the methanol to propylene (MTP) reaction. T...

Selective hydrogenation of menthone on Raney nickel catalyst

The present study deals with the selective hydrogenation of menthone to menthol in a Parr reactor. The reactions are carried out in the temperature range of 100-200°C, pressure range of 5-20 kg/cm, 100 mL solvent and catalyst to substrate ratio ranging from 0-10% for a reaction time of 4-5 h. The samples are then analyzed using a gas chromatograph for determining the conversion and then selecti...
