## Abstract

The present invention relates to a process for hydrogenating nitriles with hydrogen in the presence of a ZrO2-supported ruthenium catalyst.

## Claims

### Claim 1

A process, comprising hydrogenating at least one nitrile compound in the presence of hydrogen and a fixed-bed ruthenium catalyst supported on ZrO2.

### Claim 2 (depends on 1)

The process according to claim 1, wherein the fixed-bed ruthenium catalyst comprises 0.05 to 20 wt % of ruthenium, based on the total weight of the fixed-bed ruthenium catalyst.

### Claim 3 (depends on 1)

The process according to claim 1, wherein the process is operated continuously.

### Claim 4 (depends on 1)

The process according to claim 1, wherein the at least one nitrile compound comprises a dinitrile compound.

### Claim 5 (depends on 1)

The process according to claim 1, wherein the nitrile compound is selected from the group consisting of a cyanoethylated single alcohol, a cyanoethylated multiple alcohol, a cyanoethylated amine and an alpha-aminonnitrile.

### Claim 6 (depends on 1)

The process according to claim 1, wherein the hydrogenating does not occur in the presence of an added solvent.

### Claim 7 (depends on 1)

The process according to claim 1, wherein the hydrogenating occurs in the presence of ammonia.

### Claim 8 (depends on 1)

The process according to claim 1, wherein hydrogenation takes place at temperatures in the range from 20 to 200° C. and pressures in the range from 20 to 300 bar.
