IRON-BASED CATALYST FOR HYDROGENATING ALPHA-, OMEGA-DINITRILES

摘要

The invention relates to a substance which is suitable for use as a catalyst , containing a) iron or a compound based on iron or mixtures thereof, b) 0.001 to 0.3 wt. % in relation to a) of a promoter based on 2, 3 , 4 or 5 elements from the following group: aluminium, silicon, zirconium, titanium and vanadium, c) 0 to 0.3 wt. % in relation to a) of a compound based on an alkaline and/or alkaline earth metal and d) 0.001 to 1 wt. % in relation to a) of manganese. The inventive substances can be used as catalysts for the hydrogenation of alpha-, omega-dinitriles.
