- alkali metal-free bases such as ammonia, ammonium carbonate, ammonium bicarbonate, ammonium carbamate, ammonium oxalate, ammonium malonate, urotropin, urea, etc.
- salts used are generally not critical: since it depends primarily on the water solubility of the salts in this approach, one criterion is their good water solubility required for the preparation of these relatively highly concentrated salt solutions. It is taken for granted that when selecting the salts of the individual components, of course, only salts with such anions are chosen which do not lead to disturbances, either by causing undesired precipitation or by complicating or preventing precipitation by complex formation.
- the precipitates obtained in these precipitation reactions are generally chemically non-uniform and consist i.a. from mixtures of the oxides, oxide hydrates, hydroxides, carbonates and insoluble and basic salts of the metals used. It may prove beneficial for the filterability of the precipitates when they are aged, i. if left for some time after precipitation, possibly in heat or by passing air through it.
- the precipitates obtained by these precipitation processes are further processed to the catalysts of the invention as usual.
- the precipitation is washed. About the duration of the washing process and the temperature and amount of the washing water, the content of alkali metal, which has been supplied by the precipitant possibly used (mineral) base, are influenced. In general, by increasing the washing time or increasing the temperature of the washing water, the content of alkali metal will decrease.

Stiles, Catalyst Manufacture Laboratory and Commercial Preparations, Marcel Dekker, New York (1983), by applying a respective metal salt solution in one or more impregnation stages, wherein as metal salts z. B. corresponding nitrates, acetates or chlorides can be used.
- the mass is dried after the impregnation and optionally calcined.
- the impregnation can be carried out according to the so-called "incipient wetness” method, in which the zirconium dioxide is moistened according to its water absorption capacity to a maximum of saturation with the impregnation solution.
- the impregnation can also be done in supernatant solution.
- multi-stage impregnation processes it is expedient to dry between individual impregnation steps and optionally to calcine.
- the multi-stage impregnation is advantageous to apply especially when the zirconium dioxide is to be applied with a larger amount of metal.
- the impregnation can take place simultaneously with all metal salts or in any order of the individual metal salts in succession.
- the catalysts prepared by impregnation are dried and preferably also calcined, for example at the above-indicated Calciniertemperatur- areas.

- molding aids such as graphite or stearic acid
- the tempering temperatures preferably correspond to the temperatures during the calcination.
- the catalysts prepared in this way contain the catalytically active metals in the form of a mixture of their oxygen-containing compounds, i. in particular as oxides and mixed oxides.
- Catalysts prepared as described above are stored as such and optionally traded. Before being used as catalysts, they are usually prereduced. However, they can also be used without prereduction, in which case they are reduced under the conditions of the hydrogenating amination by the hydrogen present in the reactor.
- the catalysts are first heated at preferably 150 to 200 ° C for a period of e.g. 12 to 20 hours exposed to a nitrogen-hydrogen atmosphere and then treated for up to about 24 hours at preferably 200 to 400 ° C in a hydrogen atmosphere.
- a portion of the oxygen-containing metal compounds present in the catalysts is reduced to the corresponding metals, so that they are present together with the various oxygen compounds in the active form of the catalyst.
- the mechanical stability can be determined by measuring the so-called lateral compressive strength.
