Abstract

Process for the preparation of n-butylamines where n-butenylamines are firstly prepared by reacting 1,3-butadiene in the form of a 1,3-butadiene containing mixture obtained during the cracking of petroleum fractions or during the dehydrogenation of LPG or LNG or from GTL technology with a primary amine and/or a secondary amine under hydroaminating conditions, and the resulting butenylamine(s) are then reacted in a second process stage under hydrogenating and transalkylating conditions.
