EFFICIENCY OF TWO-STAGE HYDRODENITROGENATION OF AROMATIC NITROGEN COMPOUNDS

Article abstract of DOI:10.1246/cl.1985.909

A high hydrodenitrogenation (86 percent) of acridine on a Ni-Mo/Al2O3 catalyst was achieved by succesive reactions at 370 deg C for 2 h and 420 deg C for 3 h, respectively, while the single stage reaction at 420 deg C for 5 h removed only 67 percent nitrogen.The effective hydrodenitrogenation is postulated due to the extensive hydrogenation in the first stage and C-N bond fission in the second stage.
