Conversion of nitrobenzene to aniline

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.
