Abstract

The invention relates to a method for hydrogenation of an organic compound comprising at least one carbonyl group, whereby the organic compound is brought into contact with a moulded body in the presence of hydrogen. Said body may be produced by a method in which (i) an oxidic material is prepared, comprising copper oxide, aluminum oxide, and at least one oxide of lanthanum, tungsten, molybdenum, titanium, or zirconium, followed by (ii) addition of powdered metallic copper, copper platelets, powdered cement, graphite, mixtures or a mixture thereof with graphite to the oxidic material and (iii) moulding the mixture from (ii) to give a moulded body, characterised in that the moulded body is in the form of catalyst tablets or catalyst extrudates with a diameter d and/or height h<2.5 mm, catalyst beads with a diameter d<2.5 mm or catalyst honeycomb with a cell diameter r_z<2.5 mm.

Claims

1. A process for the hydrogenation of an organic compound containing at least one carbonyl group, said process comprising bringing the organic compound, in the presence of hydrogen, into contact with a shaped body which is produced by a process comprising:

mixing (i) an oxidic material comprising copper oxide, aluminum oxide and at least one oxide selected from the group consisting of lanthanum, tungsten, molybdenum, titanium and zirconium, and (ii) pulverulent metallic copper, copper flakes, and pulverulent cement, or a mixture thereof with graphite, to form a catalyst mixture, and then

shaping the catalyst mixture to form a catalyst pellet or a catalyst extrudate having a diameter d and/or a height h of <

2.5 mm, catalyst spheres having a diameter d of <

2.5 mm, or catalyst honeycombs having a cell diameter r_z of <

2.5 mm;

with the proviso that the shaped body does not contain one or both of zinc oxide and nickel oxide.

2. The process as claimed in claim 1, wherein the oxidic material comprises

(a) 50-80 wt % copper oxide,

(b) 15-35 wt % aluminum oxide,

and

(c) 2-20 wt % of at least one oxide selected from the group consisting of lanthanum, tungsten, molybdenum, titanium and zirconium,

wherein the summation of (a), (b) and (c) is 80-100 wt % based on the total weight of the oxidic material after calcination, and wherein cement is not included as part of the oxidic material.

3. The process as claimed in claim 2, wherein the oxidic material comprises:

(a) 55-75 wt % copper oxide;

(b) 20-30 wt % aluminum oxide; and

(c) 3-15 wt % of at least one oxide selected from the group consisting of lanthanum, tungsten, molybdenum, titanium and zirconium;

wherein the summation of (a), (b) and (c) is 95-100 wt % based on the total weight of the oxidic material after calcination, and wherein cement is not included as part of the oxidic material.

4. The process as claimed in claim 1, wherein the pulverulent metallic copper, the copper flakes, and the pulverulent cement, or the mixture thereof with graphite, is added in an amount of from 1 to 40% by weight, based on the total weight of the oxidic material.

5. The process as claimed in claim 1, wherein graphite is added in an amount of from 0.5 to 5% by weight, based on the total weight of oxidic material, to the oxidic material or the catalyst mixture.

6. The process as claimed in claim 1, wherein the organic compound is a carboxylic acid, a carboxylic ester, a carboxylic anhydride or a lactone.

7. The process as claimed in claim 6, wherein the organic compound is adipic acid or an ester of adipic acid.

8. A shaped body comprising:

an oxidic material comprising

(a) 50-80 wt % copper oxide,

(b) 15-35 wt % aluminum oxide,

and

(c) 2-20 wt % of at least one oxide selected from the group consisting of lanthanum, tungsten, molybdenum, titanium and zirconium,

wherein the summation of (a), (b) and (c) is 80-100 wt % based on the total weight of the oxidic material after calcination,

1-40 wt % of metallic copper powder, copper flakes, and cement powder or a mixture thereof with graphite, based on the total weight of the oxidic material, and

5-5 wt % graphite, based on the total weight of the oxidic material,

wherein the sum of the proportions of the oxidic material, the metallic copper powder, the cement powder, and the mixture thereof with graphite, makes up at least 95% by weight of the shaped body, and

wherein the shaped body is in the form of a catalyst pellet or catalyst extrudate having a diameter d and/or a height h of <

2.5 mm, catalyst spheres having a diameter d of <

2.5 mm, or catalyst honeycombs having a cell diameter r_z of <

2.5 mm,

with the proviso that the shaped body does not contain one or both of zinc oxide and nickel oxide.

9. The shaped body as claimed in claim 8, wherein the oxidic material comprises:

(a) 55-75 wt % copper oxide;

(b) 20-30 wt % aluminum oxide; and

(c) 3-15 wt % of at least one oxide selected from the group consisting of lanthanum, tungsten, molybdenum, titanium and zirconium;

wherein the summation of (a), (b) and (c) is 95-100 wt %, based on the total weight of the oxidic material after calcination.
