Continuous preparation of amines by nitrile compound hydrogenation |
| abstract |
Amino compounds are continuously prepared by hydrogenation of nitrile compounds in the presence of a catalyst, and more particularly diamines are prepared by the continuous hydrogenation of dinitrile compounds in the presence of a Raney metal catalyst and in the absence of an alcoholic solvent; the subject process includes extracting a portion of the catalyst present in the reaction medium, the extracted portion of the catalyst is submitted to a regeneration for providing a catalyst having a catalytic activity lower than that of a fresh catalyst but still high and the regenerated catalyst is recycled to the reaction medium together with fresh catalyst according to a predetermined ratio, whereby the consumption of catalyst is reduced per ton of amines produced. |
