Abstract
(DE) Verfahren zur Herstellung von Ethyienaminen, wobei man in einer ersten Reaktionsstufe Ethylenoxid (EO) mit Ammoniak unter wasserfreien Bedingungen an einem anorganischen Ionenaustauscher als Heterogenkatalysator kontinuierlich umsetzt, wobei das resultierende Umsetzungsprodukt Monoethanolamin (MEOA), Diethanolamin (DEOA) und Triethanolamin (TEOA) im Gewichtsverhältnis MEOA : DEOA : TEOA = 80 - 94 : 5,9 - 15 : 0,1 - 5 enthält, und das Umsetzungsprodukt anschließend kontinuierlich in einer zweiten Reaktionsstufe mit Ammoniak in Gegenwart von Wasserstoff und einem heterogenen Hydrierkatalysator umsetzt.
(EN) Disclosed is a method for producing ethyleneamines, in which ethylene oxide (EO) is continuously reacted with ammonia on an inorganic ion exchanger as a heterogeneous catalyst in anhydrous conditions in a first reaction stage, the obtained reaction product containing monoethanolamine (MEOA), diethanolamine (DEOA), and triethanolamine (TEOA) at a weight ratio MEOA: DEOA: TEOA = 80 - 94: 5.9 - 15: 0.1 - 5, and the reaction product is then continuously reacted with ammonia in the presence of hydrogen and a heterogeneous hydrogenation catalyst in a second reaction stage.
(FR) L'invention concerne un procédé de production d'amines d'éthylène. Dans une première étape de réaction, on convertit en continu de l'oxyde d'éthylène (EO) avec de l'ammoniaque dans des conditions exemptes d'eau au niveau d'un échangeur d'ions inorganiques en tant que catalyseur hétérogène. Le produit de réaction résultant contient de l'amine de monoéthanol (MEOA), de l'amine de diéthanol (DEOA) et de l'amine de triéthanol (TEOA) dans un rapport en poids MEOA: DEOA: TEOA = 80 - 94: 5,9 - 15: 0,1 5. Ensuite, le produit de réaction est ensuite converti en continu dans un deuxième étage de conversion avec de l'ammoniaque en présence d'hydrogène et un catalyseur d'hydrogénation hétérogène.
