Abstract
Nickel and lanthanum on MgO or MgO–Al2O3 catalysts were prepared and characterized. The applicability of the catalysts was studied in the liquid-phase hydrogenation of benzonitrile. A La/MgO catalyst showed surprisingly high activity and selectivity. The scope of the reaction was extended to other nitriles (benzyl cyanide, cinnamonitrile, adiponitrile) over this La/MgO catalyst.

The activity of the catalysts was tested in the heterogeneous catalytic hydrogenation of benzonitrile in methanol without any additives
Summary
Heterogeneous catalysis is a widely researched field in organic chemistry. About 85–90% of all chemical manufacturing processes require the use of a catalyst. Among these reactions about 80–85% applies heterogeneous catalysis [1]. The elaboration of new heterogeneous catalytic methods is of great importance in synthetic organic chemistry. Primary amines represent an important group of intermediates and are widely used in the pharmaceutical and herbicide industry.
