Definitions
- the present invention relates to catalysts composed of a support, optionally coated with oxides, hydroxides and oxide hydrates of rare earths and manganese, onto which Ru and Pd are applied and which are treated with (earth) alkali metal which are characterized in that they contain no halogen. and a process for the preparation of cycloaliphatic amines by hydrogenation of the corresponding aromatic precursors in the presence of the catalysts according to the invention
- aromatic amines can be hydrogenated in different ways and with different catalysts.
- the development of the relevant technique teaches that it is very difficult. all problems that arise, such as unsatisfactory conversion, lack of selectivity due to hydrogenolysis or condensation to high molecular weight compounds, insufficient resilience, activity and
- Such catalysts are suitable, for example, for the flexible production of mixtures of cyclohexylamine and dicyclohexylamine.
- Ru catalysts have a tendency to catalyze diminution and hydrogenolysis of the molecules down to methane with increasing temperatures.
- the already exothermic hydrogenation can therefore, for example, at first slowly, then, if necessary, pass very quickly into the far more severe exothermic methanation and lead to an uncontrollable situation and even explosions when Ru catalysts are used must therefore be very extensive and reliable casual safety precautions are taken, however, this jeopardizes the suitability of the very good Ru catalysts for technical systems
- the object of the invention was therefore to provide catalysts for the hydrogenation of aromatic amines to cycloaliphatic amines, which under full load bring about complete conversion, have high selectivity with regard to the formation of primary cycloahphatic amines even without addition of NH 3 and, above all, no hydrogenolysis and triggering more methanization of the substrates
- catalysts which contain Ru and Pd and are preferably applied to alcohol-supported supports or to supports covered with SE-Mn and which are strictly halogen-free.
- the invention is surprising in that the Influence of halogen ions on the catalytically active Ru in the above-mentioned sense of undesired over-activation, which causes hydrogenolysis and methanization, was not known.
- the invention is further surprising when obviously small residual amounts of halogen, which after the preparation of such catalysts from halogen-containing ones Starting materials remain in the catalyst, causing this undesirable property

- This can be done, for example, by drinking or spraying the carrier with solutions of suitable salts of these elements.
- the salts of SE and Mn are converted into oxidic compounds adhering to the support at 450 ° C.
- the application of the compounds of SE and Mn can also be carried out by the joint precipitation of SE and Mn hydroxide mixtures on the impregnated support with alkali, alkaline earth metal or NH and, if necessary, subsequent washing out of soluble portions with water.
