METHOD FOR PRODUCING AMINES BY THE HYDROGENATION OF NITRILE COMPOUNDS

摘要

The present invention relates to a method for producing amine compounds by the hydrogenation of nitrile compounds in the presence of a catalyst. The invention more particularly relates to a method for producing diamines by the continuous hydrogenation of dinitrile compounds in the presence of a Raney-metal catalyst. The method of the present invention comprises controlling the molar flow of nitrile compounds and the mass flow of catalyst in the hydrogenation piston reactor in order to minimise the occurrence of impurities and degradation of the catalyst activity.
