Abstract

PURPOSE: To suppress formation of by-products and obtain a compound useful as a raw material for medicines, dyes, surfactants, chemicals, etc., in good yield using an inexpensive catalyst, by catalytically hydrogenating benzonitrile in the presence of ammonia.
CONSTITUTION: Benzonitrile is catalytically hydrogenated in the presence of ammonia in a molar amount of 0.2W2.0 times, preferably 0.5W1.5 times based on the benzonitrile and further a catalyst, e.g. Raney nickel or Raney cobalt, etc., in a nonreducing polar solvent, e.g. methanol, etc., at 50W150°C under 50W150kg/cm2 pressure, preferably at 80W120°C under 80W120kg/cm2 pressure to afford the aimed benzylamine. The catalyst is used in an amount of 2W12wt%, preferably 5W10wt% based on the benzonitrile to carry out the reaction.
