Abstract

In a process for preparing bis(2-morpholinoethyl) ether by reacting diethylene glycol with ammonia under superatmospheric pressure and at elevated temperature in the presence of hydrogen and a hydrogenation catalyst, the catalytically active composition of the catalyst prior to reduction with hydrogen comprises PA1 from 20 to 85% by weight of aluminum oxide (Al.sub.2 O.sub.3), zirconium dioxide (ZrO.sub.2), titanium dioxide (TiO.sub.2) and/or silicon dioxide (SiO.sub.2), PA1 from 1 to 70% by weight of oxygen-containing compounds of copper, calculated as CuO, PA1 from 0 to 50% by weight of oxygen-containing compounds of magnesium, calculated as MgO, oxygen-containing compounds of chromium, calculated as Cr.sub.2 O.sub.3, oxygen-containing compounds of zinc, calculated as ZnO, oxygen-containing compounds of barium, calculated as BaO, and/or oxygen-containing compounds of calcium, calculated as CaO, and PA1 less than 20% by weight of oxygen-containing compounds of nickel, calculated as NiO, based on the oxygen-containing compounds of copper, calculated as CuO.
