<p>Alkylamine production by reaction of olefins with ammonia or primary or secondary amines under hydroamination conditions with a calcined zeolitic catalyst is such that at most 24 hours before the reaction the catalyst is heat- activated at 100-550[deg]C in a gas stream of air, nitrogen and/or other inert gases. An independent claim is also included for increasing the hydroamination activity of the catalyst by the above heat-activation process.</p> |
