Abstract

Aqueous solutions of pโ€nitrobenzoic acid were hydrogenated in the presence of Pt/C and Pd/C catalysts in a slurry reactor. External as well as internal mass transport steps were studied using a membrane H~2~โ€electrode and a metal probe electrode. After the influence of the mass transport effects was corrected for, it was possible to obtain corrected values of the kinetic characteristics of the overall chemical reaction. The mechanism was studied using potential and polarization methods.

Polarography of 5,5'-dithio bis-(2 nitrobenzoic acid) in the pH range 2-12, in Britton-Robinson buffer at constant ionic strength (0 .5 M) has been carried out. Four cathodic waves (A, B, C and D) and an anodic wave have been obtained . Wave A is produced by a reduction of pre-protonated nitro group
