TL;DR: 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 from 20 to 85% by weight of aluminum oxide (Al2 O3), zirconium dioxide (ZrO2), titanium dioxide (TiO2) and/or silicon dioxide (SiO2)) as mentioned in this paper.
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 from 20 to 85% by weight of aluminum oxide (Al2 O3), zirconium dioxide (ZrO2), titanium dioxide (TiO2) and/or silicon dioxide (SiO2), from 1 to 70% by weight of oxygen-containing compounds of copper, calculated as CuO, from 0 to 50% by weight of oxygen-containing compounds of magnesium, calculated as MgO, oxygen-containing compounds of chromium, calculated as Cr2 O3, 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 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.
