Abstract
536,940. Hydrogenation of nitriles. MAY, P. (Soc. des Usines Chimiques Rhone-Poulenc.). Nov. 2, 1939, No. 29232. [Class 2 (iii)] Primary amines are prepared by the catalytic hydrogenation of nitriles in the liquid phase, using the usual hydrogenation catalysts characterized in that there is present a strong watersoluble base having in decinormal aqueous solution a co-efficient of electrolytic dissociation greater than 0.50, such as a caustic alkali, barium hydroxide, and the quaternary ammonium bases tetramethyl-, and tri-methylammonium hydroxide. Catalvsts mentioned are nickel and cobalt catalysts, and temperatures used are generally below 100‹ C. with pressures of less than 50 atmospheres. In examples (1) stearic nitrile is hydrogenated in ethyl alcohol solution in the presence of active nickel and caustic soda at 60‹ -65‹ C. under a pressure of 20 atmospheres to give stearylamine. (2) Palmitic nitrile is hydrogenated as above to give the corresponding amine. (3) Oleyl amine is treated as above to form oleylamine. (4) Stearic nitrile is treated as in example (1) except.that the base used is barium hydroxide. (5) As in example (1) using as the base methyltriethylammonium hydroxide. (6) Adipic dinitrile is treated as in example (1) to give hexamethylene diamine. (7) As in example (6) but using cobalt as the catalyst instead of nickel.
