50 g of nonylamine and 50 g of water are introduced into a 750-ml autoclave equipped with a self-aspirating turbine. 5 g of basified Raney nickel doped with 2% by weight of Cr are added. The reactor is flushed with twice 10 bar of nitrogen and then with twice 10 bar of hydrogen. The autoclave is placed under 20 bar of hydrogen, and stirring and heating to 90° C. are carried out. The nonanenitrile resulting from example 5 is then injected using a pump, while keeping the hydrogen pressure constant in the reactor. 350 g of nonanenitrile are injected over the course of 4 h. After the end of the injection, the reaction medium is maintained under the same conditions for 30 min. The temperature is then brought back to 20° C., the reactor is flushed with nitrogen and the catalyst is filtered off. The reaction medium is then distilled under reduced pressure: in this way, the nonylamine is recovered with a yield of 98% (boiling point 201° C. under 760 mmHg).
