Abstract
The present invention relates to a process for the preparation of saturated nitrites by catalytic hydrogenation of the corresponding olefinically unsaturated compounds in the presence of a supported transition metal catalyst at a pressure of from 1 to 95 bar. Specifically, the invention relates to a process for the preparation of tetrahydrogeranonitrile (3,7-dimethyloctanenitrile) by catalytic hydrogenation of geranonitrile.

1-16. (canceled)
A process for the preparation of saturated nitrites of the formula (I)
- where the index n is an integer from 1 to 3,
- which comprises converting unsaturated nitrites of the formula (II)
- or unsaturated nitrites of the formula (III)
- where the index n is in each case an integer from 1 to 3,
- or by converting mixtures of the unsaturated nitriles of the formulae (II) and (III) in the presence of hydrogen and a supported transition metal catalyst at a pressure of from 1 to 95 bar.
