Hydrogenation of aromatic nitriles to primary amines |
| abstract |
In the process of hydrogenating aromatic nitriles to primary amines whereby the nitrile is hydrogenated in a solvent system containing added ammonia using a cobalt or nickel catalyst, the improvement of employing an ether as solvent and carrying out the hydrogenation in the presence of water in an amount of from about 10% to about 20% by volume of the ether solvent whereby the rate of reaction is increased, secondary amine by-products are reduced and catalyst may be recycled without adverse effects. |
