Preparation of alkylamines and method of increasing the hydroamination activity 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 thermally activated at from 100 to 550° C. in a gaseous stream of air, nitrogen, other inert gases...

More Information
Summary: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 thermally activated at from 100 to 550° C. in a gaseous stream of air, nitrogen, other inert gases or mixtures thereof not more than 24 hours before commencement of the reaction.
