摘要：<p>The invention provides a process for the catalytic hydrogenation of C12 to C22 nitrile to amine employing a certain nickel catalyst upon a carrier containing magnesium oxide and silica which contains from 60 to 90% (w.w.) of nickel calculated on the catalyst composition, which has a molar ratio of silica to nickel in the catalyst between 0.10 and 0.30, a molar ratio of magnesium to nickel in the catalyst between 0.25 and 0.05, a mean pore radius of the catalyst between 1.5 and 4.0 nanometers, a pore volume between 0.20 and 0.80 ml/g, an active nickel surface area of the catalyst between 90 and 150 m<2>/g of nickel and a BET total surface between 100 and 400 m<2>/g catalyst.</p>
