Abstract
Process for the continuous preparation of an amine by reaction of a primary or secondary alcohol, aldehyde and/or ketone with hydrogen and a nitrogen compound selected from the group consisting of ammonia, primary and secondary amines at a temperature in the range from 60 to 300° C. in the presence of a catalyst comprising copper oxide and aluminum oxide, wherein the reaction takes place in the gas phase and the catalytically active composition of the catalyst before reduction with hydrogen comprises from 20 to 75% by weight of aluminum oxide (AlO), from 20 to 75% by weight of oxygen-comprising compounds of copper, calculated as CuO, from 0 to 2% by weight of oxygen-comprising compounds of sodium, calculated as NaO, and less than 5% by weight of oxygen-comprising compounds of nickel, calculated as NiO, and the shaped catalyst body has a pellet shape having a diameter in the range from 1 to 4 mm and a height in the range from 1 to 4 mm.
