WebThe kinetics of the vapor-phase, catalytic hydrogenation of nitrobenzene to aniline on an industrial copper catalyst has been studied in the 503-563/sup 0/K range. A kinetic model of the process is presented which assumes the sequential addition of hydrogen from the gas phase and the absence of retardation by aniline. WebDec 1, 2011 · The present removal strategies suffer from high cost or slow conversion rate. Here, we investigated the conversion of NB to aniline (AN), a less toxic endproduct that can easily be mineralized, using a fed-batch bioelectrochemical system with microbially catalyzed cathode.

WebJul 5, 2024 · The effect of Ni/C 60 -Ac-B-4 amount on hydrogenation of nitrobenzene was shown in Table A.3. The optimum amount was 0.1 g with the nitrobenzene conversion … WebJun 1, 2016 · Aniline (C 6 H 5 NH 2) plays a significant role in both industry and daily life, and can be synthesized via catalytic hydrogenation of nitrobenzene (C 6 H 5 NO 2) over transition metals; however fundamental investigations on reaction mechanisms in the heterogeneous catalysis are still lacking. WebOct 14, 2024 · High conversion (> 90%) of aniline in all the solvents was observed, but the conversion is 100% in acetonitrile with greater selectivity (93%) to nitrobenzene. Under homogeneous conditions, the nitroso intermediate would be better stabilised by the imidazolium groups in the catalyst which on further oxidation gives nitro product [ 43 ]. genesis obituary
