Abstract
Catalytic hydrogenation of mdinitrobenzene over Pt/TiO2–Al2O3 catalysts was investigated The effect of the enrichment of TiO2 was analyzed The results showed that the increase in TiO2 content produced an enhancement in the activity of the catalyst In these consecutive reactions both rate constants k1 and k2 were determined and it whatever the catalyst k1 is higher than k2 The limiting step of the reaction was the transformation of mnitroaniline to mphenylenediamine This behavior was explained by the modification in the acceptordonor electron character of the group in the meta position
