| 摘要 |
<p>The present invention relates to a process for the preparation of amines by hydrogenation of aromatic nitrocompounds in liquid phase, which comprises supplying a first reactor (2) comprising at least one catalyst with a feed (9) of gaseous hydrogen and a feed (8) of liquid aromatic nitrocompounds; hydrogenation in the first hydrogenation reactor (2) by contracting the gaseous phase with the liquid phase to obtain a product containing aromatic amines; forwarding the liquid and gaseous phases present in the first reactor (2) to a second polishing reactor (13); and contacting gaseous phase material present in the polishing reactor (13) with the liquid phase to allow further hydrogenation of any remaining aromatic nitrocompounds and/or intermediates, wherein the polishing reactor (13) is fed liquid phase and gaseous phase material forwarded from the first reactor. The present invention further relates to a system therefore.</p> |
