Metal-Free Reduction of Nitrobenzene to Aniline in Subcritical Water
An
environmentally friendly approach for the reduction of nitrobenzene
to aniline promoted by carbonaceous bio-based materials was successfully
achieved under subcritical water conditions. The proposed methodology
features a metal-free process, no-hydrogen input as reductor, the
use of commercial bio-based carbon materials having low cost and availability,
and water as green solvent under subcritical conditions. Using optimized
conditions, reduction of nitrobenzene in the presence of commercial
NORIT GAC 12-40 or DACARB PC1000 was accomplished at 310 °C for
6 h and quantitatively furnished the target aniline. Treatment of
NORIT GAC 12-40 with KOH allowed to decrease charcoal loading (6 g
vs 40 g) and increase aniline yields (80% vs 66%)
