Procedure

1000 g n-butyraldehyde are reacted in the presence of 80 g of a commercially available nickel containing carrier catalyst (containing about 52 to 53% by weight nickel, and employing chromium (3)-oxide as activator) at 115° C with ammonia and hydrogen (volume ratio 1 : 1) in a flask equipped as described in Example 1. Altogether 260 l ammonia and 260 l hydrogen are introduced into the aldehyde-catalyst-suspension over a period of 4 hours. After termination of the reaction, the catalyst is separated from the reaction mixture. 840 g butylidene-butylamine are obtained.
