Abstract

The present invention relates to a process for producing a supported tin-comprising catalyst, wherein a solution (S) comprising tin nitrate and at least one complexing agent is applied to the support, where the solution (S) does not comprise any solid or has a solids content of not more than 0.5% by weight based on the total amount of dissolved components.

First claim

The invention claimed is:

1. A supported tin-comprising catalyst which is produced by a process wherein a solution (S) comprising tin nitrate and at least one complexing agent is applied to the support, where the solution (S) does not comprise any solid or comprises a solids content of not more than 0.5% by weight based on the total amount of dissolved components, wherein the catalyst comprises
i) from 0.2 to 5% by weight of tin,
ii) from 15 to 80% by weight of aluminum,
iii) from 1 to 20% by weight of copper,
iv) from 5 to 35% by weight of nickel and
v) from 5 to 35% by weight of cobalt,
where the proportions by weight of the components i) to v) are determined as oxides after a calcination step and before a reduction step using hydrogen.

2. The catalyst according to claim 1 , wherein the catalyst does not comprise any chlorine.

3. A process comprising preparing an amine (A) in the presence of the catalyst according to claim 1 .

4. The process according to claim 3 , wherein a primary alcohol, a secondary alcohol, an aldehyde or a ketone is reacted with hydrogen and a nitrogen-comprising compound (N).

5. The process according to claim 4 , wherein the nitrogen-comprising compound (N) is ammonia, a primary amine or a secondary amine.

6. The process according to claim 3 , wherein the primary alcohol, the secondary alcohol, the aldehyde, the ketone or the nitrogen-comprising compound (N) is used as aqueous solution.

7. The process according to claim 3 , wherein the amine (A) is at least one amine selected from among monoaminodiglycol (ADG), morpholine, N—(C 1-4 -alkyl)morpholine, 2-(2-di(C 1-4 -alkyl)aminoethoxy)ethanol, bis(2-di(C 1-4 -alkyl)aminoethyl) ether, monoethanolamine (MEOA), 1,2-ethylenediamine (EDA), polyetheramines, piperazine, diethylenetriamine (DETA) and polyisobutenamine (PIBA).

8. The process according to claim 3 , wherein monoaminodiglycol (ADG) and morpholine are prepared by reacting diethylene glycol (DEG) with ammonia.
