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.
制备
正丁胺的过程,首先通过在石油分馏或液化石油气(L
PG)或液化天然气(LNG)脱氢或GTL技术过程中获得的含有
1,3-丁二烯的混合物中,使用一种主要胺和/或二级胺在
水合胺条件下反应制备n-
丁烯基胺,然后在第二个过程阶段在加氢和转移烷基化条件下反应所得的
丁烯基胺。
