A process for preparing alkylamines and to increase the Hydroaminierungsaktivität of calcined zeolitic catalysts

In a process for preparing alkylamines by reacting olefins with ammonia, primary or secondary amines under hydroaminating conditions over a calcined zeolitic catalyst, the calcined zeolitic catalyst is up to 24 hours before the reaction at temperatures in the range of 100 to 550 ° C in a gas stream from air, nitrogen, other inert gases or mixtures thereof thermally activated.
